Workaround: Do not call the Win32 API functions LoadLibrary and FreeLibrary to load and unload a LabWindows/CVI built DLL from different threads.
| |||||
| 288099 Return | The ProgressBar_GetPercentage function panel defines the percentage parameter to be an input parameter. Because the percentage parameter is actually an output parameter, declaring a variable from the function panel will result in a variable of the wrong type being declared. It will be declared as a double * instead of a double. Workaround: Add the percentage variable manually instead of declaring it from the function panel.
| |||||
| 288389 Return | The splitter control can disappear after is it dragged. This issue occurs only on Windows 7 or Windows Vista with Aero enabled. Workaround: Create a callback function for your splitter controls. In the EVENT_DROPPED case, hide the control, delay for a short amount of time, and then display the control. For example, adding the following code to the EVENT_DROPPED case of the splitter callback function should cause the splitter to display whenever it is dropped. SetCtrlAttribute (panelHandle, PANEL_SPLITTER, ATTR_VISIBLE, 0); Delay (.02); SetCtrlAttribute (panelHandle, PANEL_SPLITTER, ATTR_VISIBLE, 1);
| |||||

| 316930 Return | Possible to see 100% CPU usage when a graph or strip chart is on screen and axis labels are visible For this problem to occur at least one axis label must visible. When label strings get too close to the edge of the control, they will attempt to reposition themselves inward to avoid being cut off, but in some cases the repositioning algorithm will reposition to the same value and cycle endlessly. There is no visible behavior issue caused by this problem on Windows other than high CPU usage. This problem is most likely to occur with one of the x-axis label strings if the x-axis has negative values or ATTR_FIXED_PLOT_AREA is enabled and ATTR_PLOT_AREA_LEFT is set too close to the edge. Workaround: There are two workarounds: 1) Disable the axis label string. 2) Enable ATTR_FIXED_PLOT_AREA and then set ATTR_PLOT_AREA_LEFT (if the problem is happening with the left x-axis) to a value a few pixels over to the right until the problem stops occurring. The value this needs to be set to is dependent on the font and min/max of the affected scale so a precise value can't be given.

| |||||
| 428584 Return | The DDC_Get[File/ChannelGroup/Channel]StringPropertyLength functions incorrectly return the number of characters instead of size in bytes. This is a problem only when called on a string property whose value contains multibyte characters on a system with a corresponding multibyte code page selected. Workaround: Allocate a buffer that is twice the size reported by DDC_Get[File/ChannelGroup/Channel]StringPropertyLength plus an addition byte for the NULL terminator or arbitrarily large enough to hold the longest string value you might have stored in a property. Pass this buffer and the corresponding buffer size to the DDC_Get[File/ChannelGroup/Channel]Property or DDC_Get[File/ChannelGroup/Channel]PropertyString functions. This will ensure you get the full string property value stored in the file. After obtaining the string property value in the buffer, call strlen or an equivalent function to determine the actual size of the string in bytes if needed. This issue has been fixed in LabWindows/CVI 2013 SP1.

| |||||
| 437134 Return | GetCVIState and GetCVIStateEx sometimes return the wrong state between the build-time and run-time of a project. When building and running a project, there is a window of time in which the project has been built but has not yet started running. During this time, GetCVIState and GetCVIStateEx return the same state as after the project has begun running. Consequently, a program that is checking if the project has finished executing might incorrectly think that the project has finished executing, when it has not started yet. This happens very infrequently. Workaround: Delay the check long enough so that the project has actually started running when these functions are called.
| |||||
| 443791 Return | LabWindows/CVI is not visible when terminating a debugging session if Hide windows when application is running is enabled after starting to debug the application If Hide windows when application is running is enabled (Options»Environment) during a debug session, LabWindows/CVI will incorrectly minimize upon termination of the debug session.
