If the 64-bit project is the active project, the import libraries of the 32-bit project will show as dimmed and 64-bit.

Changing the active table cell can incorrectly send the EVENT_ACTIVE_CELL_CHANGE event multiple times.
If, inside a callback function that handles EVENT_ACTIVE_CELL_CHANGE, you do something to change the focus of the panel (for example, displaying a message popup), the event is sent a second time after the callback finishes executing.

Workaround: You can use the following code to handle the second, incorrectly sent event.

void CVICALLBACK FlagClearFunc (void *callbackData)

{

*(int *)callbackData = 0;

}



int CVICALLBACK TableCB (int panel, int control, int event, void *callbackData,

Return
Some large source files take much longer to compile in LabWindows/CVI 2013.
The following is true of the new LabWindows/CVI 2013 compiler:
  • Single-file compilation is slower in 2013, regardless of what comprises the code.
  • Multi-file compilation is faster in 2013 because of concurrent compiles. Whether this completely makes up for the slower single-file compilation time or not depends on the number of files, size of the files, and so on.
  • The 2013 linker is faster. This, together with the second bullet, will generally make builds faster in 2013.
  • The build time of an Edit-Build-Debug cycle is also faster in 2013, but only marginally so, because the first and third bullets are applicable and mutually cancelling. The second bullet is not applicable in most cases.
  • Compiling a PCH file is much faster in 2013. This only impacts the very first build of a project, the first build following a clean, or a rebuild.

Generating HTML help from source with array pointer type parameters results in an 'unknown' type generated in the help.
The following function declaration causes this type of error:

Workaround:
  • Define your parameter using exclusively a pointer.
  • Use a type definition to separate the type declaration of the array from the pointer as follows:

    typedef double tArray[4];

    static int func(tArray* dataArray);

These prompts can occur with the following scenarios:

  • When you edit the graph cursors, graph annotations, or strip chart traces dialog boxes, and you modify only the active item control (Number of Cursors, Current Annotation, or Number of Traces), you have not modified the state of the control. Therefore, you should not be prompted with a confirmation of changes message if you try to exit the dialog box without saving (by clicking the panel's close button). However, the prompt appears.
  • If you modify only the axis name option in the Edit Axis Settings dialog box and try to exit without saving (by clicking the panel's close button), you should be prompted to save your changes. Yet, the prompt does not appear.
  • When you edit most sub-dialog boxes of the main Edit Graph or Edit Strip Chart dialog boxes, and you make some changes in those sub-dialog boxes but then exit without saving changes (by selecting Yes in the "Are you sure you want to discard the changes" prompt), when you then exit the main dialog box without making any further changes (by clicking the main dialog's close button), you should not be prompted to save changes.

The LabWindows/CVI debugger does not recognize variables that include the $ symbol as part of the variable name.
If you view the value of a variable with a $ in its name in the Variables window while debugging, you will see an Error: Unrecognized Identifier error.

Workaround: The C language specification states that $ is not a valid character to include in a variable name, so it is best to avoid using this character in variable names. This will prevent the error from occurring in the Variables window.

The function prototype tooltip will not appear if a struct containing a member with the same name as the function is declared between the function declaration and function definition.
The function prototype tooltip will not be displayed if a struct is defined between the function declaration and function definition if the struct contains a member with the same name as the function. For example, in the following code, a function prototype tooltip will not be displayed when the foo function is used:

int foo(int param);

struct myStruct {
int foo;
};

void main() {
foo( // Function prototype tooltip will not be displayed when this line is typed

Workaround: Avoid defining structures between function declarations and definitions when the structure contains a member with a name shared by the function. For example, the code could be written in this way:


struct myStruct {
int foo;
};

int foo;

void main() {
foo( // Function prototype tooltip will not be displayed when this line is typed
