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.

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.

LabWindows/CVI 8.0 distributions cannot include the ActiveX container merge module if LabWindows/CVI 2009 or later is installed on the same system.
This issue occurs because the name of the merge module changed in LabWindows/CVI 2009, and LabWindows/CVI 8.0.x attempted to find merge modules by name.

Workaround: Create a copy of C:\Program Files (x86)\Common Files\Merge Modules\ActiveX_Container.msm and rename the copy to C:\Program Files (x86)\Common Files\Merge Modules\ActiveX Container.msm.

LabWindows/CVI evaluates the Drivers & Components dependencies before rebuilding the project.
When you create a distribution, LabWindows/CVI automatically checks the dependencies of your project outputs to recommend which drivers and components need to be included. This check occurs before checking if the project needs to be rebuilt. If changes have been made to the project since it was last built, this can result in an inaccurate list of driver and component dependencies.

Workaround: Rebuild the project before creating a distribution configuration.

The progress bar might not draw correctly when it is overlapped by other controls.
If your progress bar is updating automatically, a common mistake is to not process events for the thread that owns the progress bar as the progress bar is updating. For more information, refer to the help for the VAL_PROGRESSBAR_AUTO_MODE value for the ATTR_PROGRESSBAR_UPDATE_MODE attribute here. However, even if you are processing events, the progress bar may not draw correctly.

Workaround: Toggle the visibility of the progress bar before it needs to redraw. For example, if you are manually updating the progress bar, you could do the following:




SetCtrlAttribute (panelHandle, PANEL_PROGRESSBAR, ATTR_VISIBLE, 0);

SetCtrlAttribute (panelHandle, PANEL_PROGRESSBAR, ATTR_VISIBLE, 1);

ProgressBar_SetPercentage (panelHandle, PANEL_PROGRESSBAR, newPercentage, NULL);




Otherwise, if the progress bar is updating automatically, you would toggle the visibility of the progress bar before you processed events, similar to the following:




SetCtrlAttribute (panelHandle, PANEL_PROGRESSBAR, ATTR_VISIBLE, 0);

SetCtrlAttribute (panelHandle, PANEL_PROGRESSBAR, ATTR_VISIBLE, 1);

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.

Workaround: For the labels, disable the Size to text option in the Label Appearance section of the Edit Control dialog box.
