• Visual FoxPro Convert month to numeric

  Dear all, i using vfp7. Do there a function i can convert "June" to 6 i mean to numeric formats. Thanks in advance. AFAIK there is no function in VFP that does parse a monthname to its numeric format nor parse a date/datetime that contains monthnames (such as June 3,2006 to 6/3/2006). You can create your own MonthName2Numeric function. ie: #define Months "January,February,March,April,May,June,July,August,September,October,November,December" ALines(aMonths,Months,.t.,',') "June is", Ascan(aMonths,'june',1,-1,1,1+2+4+8) ...Show All

• Visual C++ including dshow.h compiles not with /clr but with /clr:oldSyntax

  Hello, can somebody tell why I get 103 errors with /clr and none with /clr:oldSyntax when I include the dshow header file. I would like to use the new syntax. Win32 console app generated by VC Express with line added to include dshow.h #include "stdafx.h" #include <dshow.h> int _tmain(int argc, _TCHAR* argv[]) {     return 0; } Regards, stax You have nailed down the problem: the new C++/CLI syntax is (as its name indicates) just now being released with Visual Studio 2005. Thus, the code inside the SDK from VS 2003 is written using the old syntax and cannot be compiled without t ...Show All

• Smart Device Development trapping FN key

  Currently, on my device, to enter numbers using the QWerty keyboard, i have to press the function key each time, as there is no NumLock function available. So i thought i might be able to simulate this by implementing the following rule: -create a background process that will determine if the function key is pressed twice quickly -if so, i set a private property, _numLock = true; -if the FN key is pressed twice again, i set _numLock = false; -basically, i would like to have a process recieve all keystrokes, if _numLock = true, i can then pass the keystrokes on, but also set what ever needs to be set to indicate the FN key is pressed. i thoug ...Show All

• Visual Studio .NET-BroadcastEventWindow error on program termination

  I get an application error (.NET-BroadcastEventWindow . . .) when closing my application IF I open a Crystal Report.  If I run the program without doing any reporting, it closes fine.  This problem occurs both on the development machine and with the app deployed to a client machine. The environment is VS2005 Beta 2.  In doing some searching, it appears others have had this problem (though not necessarily with VS2005 Beta 2) and seemed to indicate it has something to do with the file crqe.dll.  However, I haven't found any solutions. Any help with this is much appreciated. - Tom I have al ...Show All

• Windows Forms DataGridView Performance issues with CellFormatting

  Hello: I'm using the DataGridView for displaying data to the user. The number of records that will be displayed at a certain time could vary between 0 and 150. I use the CellFormatting event handler to do some formatting like changing the font face and the background colors based on the cell values. Earlier we were iterating through the rows of the gridview to accomplish the same. Since the performance was dreadful, I changed the code to use the CellFormatting. Now, the performance when the gridview loads is a lot faster than the earlier approach. But everytime, we scroll through the gridview the application just hangs, and its bec ...Show All
