| 413695 Return | 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. Radial controls such as the gauge, meter, and knob must maintain a consistent aspect ratio for the radial portion of the control. 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. Workaround: Use the splitter control to resize controls rather than the Scale Contents On Resize option. Refer to the docking.cws example for details on how to accomplish this with splitter controls.

| |||||
| 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.
