The EXCEL.EXE process crashed. Exception code: 0xC0000409.
Hi, We are currently facing excel crash issue when we are tring to save .dwg file from our desktop application...saveAs Dialog is triggering SaveAsExternal.exe application which is internally using excel # #Save As the file from within SPID. saveAsExternalProcess = Sys.WaitProcess("saveasExternal", 50000) if not saveAsExternalProcess.Exists: Log.Error("saveasExternal process did not start within timeout") else: btn = saveAsExternalProcess.FindChild("WndCaption", "&Close", 3) if btn.Exists: closeButton = btn closeButton.ClickButton() else: Log.Message("saveasExternal process completed (process exited or close button not found)" exactly at line btn = saveAsExternalProcess.FindChild("WndCaption", "&Close", 3) we are getting the error as shown in the log The EXCEL.EXE process crashed. Error: Exception code: 0xC0000409. Process identifier (PID): 11468. Dump file: EXCEL_ue_9c850e00.dmp. note: if i put a breakpoint at line btn = saveAsExternalProcess.FindChild("WndCaption", "&Close", 3) and wait till the process is completed it is working fine can you please look into this issue, Thanks
Oracle Forms window with dynamic name - unable to click on subsequent runs
I have this little beast... The name of this is: Aliases.java.bufferedframeOciDev1RemoteSiteTc.windowFormsCashDrawerNumberIs542.buttonbar.ClickItem("OK"); The next time I run this test it will be named: Aliases.java.bufferedframeOciDev1RemoteSiteTc.windowFormsCashDrawerNumberIs543.buttonbar.ClickItem("OK"); I have tried several ways of replacing '543' with the var drawerNo, but then the object isn't found. If I do var winName = windowFormsCashDrawerNumberIs + drawerNo The object still can't be found. How can I get TC to recognize this window when it's name changes each time I run the test? I've recorded a keyword test several times, converted it to a script (JS) and made adjustments with no luck.
QT - Error No such interface supported
Has anyone been able to test modern QT applications 6.7 or 6.8 and get it to work. I cannot even get the simple example applications from QT to function. According to support currently 6.7 and 6.8 are supported, but neither seem to work. Just using the object browser shows error for most items, and none of the QT related methods are even displaying or accessible. See attached image. Any one have a solution to this? **I tried to upload a small zip file that contains the QT sample app, but the forum prevents it from being uploaded.
Avalonia - XPF desktop app automation
Hi Team, We are migrating our WPF app using Avalonia XPF, and evaluating automation possibility using Test complete but unable to inspect object/controls for the same. Does Test Complete doesn't support Avalonia XPF application for windows?? If not, do we have plan to support it in near future?
OCR in UI Test Automation: Extending Coverage Where Traditional Identification Breaks Down
Automated UI testing increasingly operates in environments where traditional object identification is not reliable. Modern applications frequently render text and controls using custom graphics, canvases, charts, and dynamically generated visuals that do not expose accessible properties or stable locators. As a result, automation tools that rely solely on object hierarchies and properties can struggle to validate what is actually presented to the user. Optical Character Recognition (OCR) addresses this gap by enabling automation to extract and interpret text directly from what is rendered on screen. Instead of depending on the underlying implementation of a control, OCR works at the visual layer, analyzing pixels and patterns to recognize characters and convert them into machine readable text. This capability allows automated tests to validate user visible content in situations where traditional approaches fall short. Why OCR Matters in Real World UI Testing In many business critical applications, text is not always exposed through standard UI controls. Common examples include: Charts and dashboards rendered using custom drawing libraries Canvas based interfaces and rich graphical components Embedded documents such as PDFs or reports Custom buttons, labels, or alerts built without standard accessibility metadata In these scenarios, the risk is not just test fragility it is blind spots. If automation cannot confirm what text is displayed, teams are forced back to manual validation for critical user facing information. OCR enables tests to verify visible content regardless of how it is implemented. By converting visual text into actionable data, OCR allows teams to assert that values, labels, messages, and statuses shown to users are correct, even when object level access is unavailable. This makes OCR especially valuable for validating end-to-end business workflows where correctness depends on what users actually see, not just what the application internally represents. OCR as Part of TestComplete’s Object Recognition Strategy TestComplete incorporates OCR as part of its broader approach to handling complex and non standard user interfaces. OCR is available directly within the platform and can be applied to many different types of application testing without requiring separate tools or configurations. When TestComplete encounters unsupported or custom controls, OCR can be used to: Recognize text from a specified screen region Extract and compare visible text against expected values Locate UI elements based on displayed text rather than coordinates Interact with visual elements by identifying their text content OCR actions can be recorded automatically during test creation when traditional object recognition is not possible. Teams can also explicitly define OCR based checkpoints to validate messages, labels, and dynamic values that appear during test execution. By allowing interactions to be driven by recognized text instead of fixed screen positions, OCR based tests tend to be more resilient to layout changes and UI adjustments. See OCR in Action A short demonstration shows how OCR is applied in real testing scenarios, including recognizing text in custom or unsupported controls, validating user visible messages, and driving interactions based on on screen text rather than fixed coordinates. The demo focuses on practical use cases where traditional object identification is not available. Expanding Automation Coverage Without Increasing Fragility One of the persistent challenges in UI automation is balancing coverage with maintenance. Scripts that rely on brittle locators or coordinates often fail when visual layouts change, even if the underlying functionality remains correct. OCR helps mitigate this issue by anchoring tests to user visible content rather than implementation details. This is particularly useful for: Validating alerts or error messages drawn directly on the UI Verifying values inside charts or graphical widgets Testing applications with frequent visual refinements but stable business logic By enabling validation at the visual layer, OCR reduces the need for workarounds or manual testing in areas that were previously difficult to automate. The result is broader coverage with fewer fragile dependencies. OCR as a Bridge Between User Experience and Automation OCR is not intended to replace traditional object based testing. Instead, it complements it by extending automation into areas where conventional techniques are insufficient. Within TestComplete, OCR functions as a bridge between how users experience an application and how automated tests validate it. When automation can read and verify the same information a human user relies on, test results better reflect real world behavior and risk. As applications continue to evolve toward richer and more visually driven interfaces, OCR plays a key role in ensuring automated testing remains aligned with actual user experience not just underlying code structure.Stop Skimming PDFs, Start Automating PDF Testing
On the surface, PDFs look simple, but testing them is a whole different story. Invoices, contracts, statements, compliance reports… they’re often the last thing that lands in a customer’s hands. That also means even the smallest issue, like a missing field or a misplaced decimal, can turn into something big. The challenge is that PDFs aren’t like web pages or apps where you can easily inspect elements. They’re containers packed with content, layout, images, and data from different systems. When you add in dynamic content that changes for every customer, formatting that has to stay perfect, and the regulatory risks in industries like finance or healthcare, you start to see why manual testing just doesn’t cut it. It’s slow, inconsistent, and doesn’t scale. This is where automation becomes essential. With automation, you can make sure data is always accurate, layouts stay consistent, and testing scales across thousands of documents without slowing down your team. Instead of spending hours opening PDFs by hand, QA can focus on higher-value work while still knowing that every report or statement going out the door is right. That’s exactly where TestComplete comes in. It’s built to handle the tough parts of PDF testing so you don’t have to. You can validate content down to the last character, run visual checks to keep layouts consistent, and plug it all straight into your CI/CD pipeline. The result is faster releases, fewer headaches, and a lot more confidence that the documents your customers see are exactly as they should be.Beating SAP Testing Bottlenecks with TestComplete
Testing SAP is hard for all the familiar reasons, complex UIs, transports that tweak screens, sensitive data, and heavy audit needs. Below are the common bottlenecks and how TestComplete helps you cut through them. Fragile object locators in SAP GUI The bottleneck: SAP GUI controls can be tricky to identify reliably minor UI changes or different dynpro states can break scripts. How TestComplete helps: It provides native support for SAP GUI for Windows with extended objects (buttons, edit fields, grids, etc.), so you work with properties and methods not coordinates. Pair that with Name Mapping (a central, alias-based object repository) to make tests readable and resilient. 2) UI drift after transports equals flaky tests The bottleneck: After a support pack or transport, object properties change and tests fail even though the flow still works. How TestComplete helps: Self healing tests automatically look for close matches when an object isn’t found, reducing “false red” failures and maintenance. 3) “Hard” screens, canvas elements, or remote sessions The bottleneck: Custom controls or canvases don’t expose stable object trees. How TestComplete helps: Use AI-powered OCR (and the OCR Action in Keyword Tests) to find text on screen and create easy validation as a fallback when classic object IDs aren’t reliable. 4) Test data sprawl (pricing, partners, plants…) The bottleneck: You need many variants to cover conditions, taxes, partners, plants, and languages without hand cloning tests. How TestComplete helps: Built-in data driven testing lets you drive one test with rows from Excel/CSV/DB, multiplying coverage while keeping scripts lean. 5) Audit evidence for SOX/GxP The bottleneck: Auditors want traceable, reviewable evidence: who ran what, where it clicked, and what was on screen. How TestComplete helps: Test Visualizer captures step-by-step screenshots during record/playback; Video Recorder can capture full-run videos; detailed logs tie everything together. These are ideal for defect triage and audits. 6) CI/CD traceability (and repeatability) The bottleneck: Manual runs don’t scale; teams need runs linked to commits/builds. How TestComplete helps: Use the Jenkins plugin to trigger suites in jobs or Pipelines and view results in Jenkins, creating a clean chain of custody for each build. Final thought SAP is always changing, your tests shouldn’t break every time it does. TestComplete’s native SAP GUI support, Name Mapping, self-healing, OCR fallback, and data-driven runs help you keep testing stable and audit friendly with less maintenance. The following demo illustrates these features in practice, automating the creation of a purchase requisition within SAP while maintaining stability across UI changes.
Hover Button...
When using the TestComplete Desktop module for record‑based automation testing, there are cases where a button is not visible and therefore cannot be clicked. This happens when the button only appears on mouse hover. When the mouse is manually moved to that position, the button becomes visible, but during the recorded automated test the button does not appear and the test cannot proceed. What is the best way to hover over a button that is not visible during the test and then click it? <<= Look !!!
