CNVProcessIsRunning may incorrectly report that the process is running if the program is run as a startup program.

The progress bar might not draw correctly when it is overlapped by other controls.

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:

Ring control label/value pairs precision does not persist when changed.
When the precision of a double or float label/value pair is modified in the User Interface Editor, the precision attribute is restored to its original value when the Edit Label/Value Pairs dialog box is opened again.

Workaround: This behavior occurs only if there is only 1 label/value pair. Multiple label/value pairs persist the precision attribute. If you want only 1 label/value pair, add a second label/value pair and then change the precision attribute. Close the Edit Label/Value Pairs dialog box by clicking OK. Return to the Edit Label/Value Pairs dialog box and remove the second label/value pair. The precision attribute will now persist this value.

Radial controls do not resize all elements proportionally.
Some controls will not scale all elements proportionally when the Scale Contents On Resize panel option is enabled and they are resized.

However, this is not necessary for some elements of the control such as the label. These elements will not be scaled the same. This can cause elements to become misaligned or overlap.

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.
