Never mind. It was a precompiled header thing. Doh.

I'm including <concurrent_vector.h>, which Express seems to recognize. However, when I declare a concurrent_vector<double> variable, Express does not recognize it as a valid data type. I have been...

I see the light. Thanks.


Why not just allow operator= to be overloaded? I don't find every operation requiring a += type assignment to be natural.

What I'm doing is taking the fast Fourier transform of buf. It correctly resides in buf after the operation, but matrix is unchanged.



public class Cmplx:System.IFormattable
{
#region...

buf = new Cmplx[matrix.Rows];

for (int m = 0; m < matrix.Rows;++m)
{
buf[m] = matrix.Matrix[m][col];
}

Nevermind. I wasn't where I thought I was in the document.

Here is the code. " pData->operator[](m)[k] " returns a CString. The small font is never selected.

I'm trying to make sure a string will fit in a rectangle. I call GetTextExtent on the string and get a cx value much less than the width of the CRect object. However, when the string is drawn with...

Yep. I'm a doofus. That was it. A whole stack of windows were open. Thanks.

I'm trying to run a Visual Studio workspace from a previous version of Studio on version 6. The workspace compiles and runs properly. However, when I try to access the resources in the workspace...

Nevermind. I found the screwup. I had included an h file that declared a global variable in a cpp file which also had an extern statement for that variable. Seems like the compiler would have...

Suddenly I'm getting a "KERNEL32.DLL 0xC0000005 access violation" exception when I exit my program in the debugger. It runs fine until it is closed. The exception is raised even if all I do is run...

I believe *temp2 is equivalent to temp2[0] because the name of an array is a pointer to the first element. I'm not familiar with the class string, but

char temp[3] = {'1', '2', '3'};
cout <<...

I've gotten code like this to work:


CString array[] = { "a", "b", "c"};

array[2] is equal to "c".

Have you tried <windows.h> instead of "windows.h" ?

Didn't work. I tried declaring a global int variable in CApp, don't use it, and get the same errors.

I'm trying to use a global CCriticalSection variable to synchronize a worker thread. The global thread function and two classes use the variable. I have tried declaring it in one of the classes .h...

The key is a CString, not user-defined. Wouldn't CMap be able to handle it since some specialized CMap objects use CString keys? I'll try it, though.

I'm declaring a global CMap variable in an h file in a VC++ project. The compiler won't recognize the CMap declaration.



#include<afx.h>
#include<afxtempl.h>

Great stuff, Paul. Thanks.

Interchange the statements "upper = middle - 1" and "lower = middle + 1". If list[n + 1] < list[n] for all n, then list[middle] > key means the key is at a higher index than middle, i.e you want to...

I downloaded a C math library that I'm trying to use in Visual C++. I created a project as a static library, added all the files to the project, compiled, and linked it. I then copied the .LIB file...

My code isn't much more complicated. In OnInitialUpdate() I set the scroll size equal to a width of 150 characters and a height of 100 lines by selecting the font into a CClientDC and using...
