I'm missing the boat here on something. I have this constant, and I just want to count how many ampersands are in it. But I keep getting a character or type mismatch, I can't go though each character to check the value.
Overall, it's my idea of how to replace the mid function used in vb. mid(szFormat, 1,1)
const WCHAR LICENSEKEY_FORMAT [] = L"&&&&-&&&&-&&&&-&&&&";
for (int i = 0; i <= dwLength; ++i) {
if (wcsncmp(szFormat [i], L"&", 1) ==0) {
++dwCount;
}
}
The error I keep getting is
error C2664: 'wcsncmp' : cannot convert parameter 1 from 'WCHAR' to 'const wchar_t *'
If I szFormat[i] == L"&", I sort of get the same error.
Question:
Is it the const that I made is not stated correctly?, If not, what correction do I need?

try:
wcsncmp( &szFormat[i], L"&", 1 ) == 0
The difficult we do right away...
...the impossible takes slightly longer.

That did the trick,
Thanks Richard

Use this (note the single quotation marks):
if (szFormat [i] == L'&')
You may also have a look on the CString class which provides the Left(), Mid(), and Right() functions.

I changed it to char, so the single quotes don't work right now. I might change it back to WCHAR today, because I'm not getting the desired results. I do get an accurate count, but I'm trying to translate a vb function, so it needs to be the same.
I'm going to post an extension to the post above in about 10 minutes.

int wcsncmp( const wchar_t *string1, const wchar_t *string2, size_t count );
szFormat[i] is not a addr
for (int i = 0; i <= dwLength; ++i) {
if (wcsncmp(&szFormat [i], L"&", 1) ==0) {
++dwCount;
}
}

Hi everyone, I want to develop an application or whatever (driver), this will run before windows starts, and will ask for a password and if the password is correct system will continue to the windows. What can I do? Thanks.

The simplest thing would be to add a BIOS password[^].

Take a look at GINA[^], I think that is what you need to work with.

I want to launch a web address with ShellExecute in hidden way :
CString sLink = _T("http://www.codeproject.com/somepage/");
ShellExecute(NULL, NULL, sLink, NULL, NULL, SW_HIDE);
and goes well, but also, I want to close the launched application after execution ... how could I ?

If you want control over the spawned process, use CreateProcess()[^] instead.

Try using ShellExecuteEx() instead. It gives you back information that you can subsequently send to TerminateProcess().

Hello,
I have trouble with an OnSize handler.
In the OnSize Handler of a view I call a "Tab->MoveWindow(...)"
But in this Tab-Control (of kind CBCGPTabWnd) I never step into the OnSize Handler when I'm sizing the framewindow.
I tested it with breakpoints and OutputDebugStrings.
I even set a breakpoint into the WindowProc function to test if a WM_SIZE message occurs, but it never happens.
If I reproduce this strange effect on 2 computers, it works all fine on the first, but the second one has this effect.
It's the same Exe-File, both computers are using Windows 7 64bit (with Visual Studio 2010)
Does anyone knows a solution??
Thanks ahead 
Best wishes, Jan

I am trying to get the resolution of all the monitors that are on connected to the system. Here is how I am trying to do
1) Read number of monitors in the system
2) For each monitor get the device info using EnumDisplayDevices().
3) In step2, I am getting all the info including DeviceName
4) Using the DeviceName from above I am calling EnumDisplaySettings(), but this function is always returning false except when I use NULL for the first parameter where it gives me details of primary monitor.
Any ideas why its returning false when using the DeviceName from step2.
thanks

Quoting from MSDN:
Graphics mode indexes start at zero. To obtain information for all of a display device's graphics modes, make a series of calls to EnumDisplaySettings, as follows: Set iModeNum to zero for the first call, and increment iModeNum by one for each subsequent call. Continue calling the function until the return value is zero.
When you call EnumDisplaySettings with iModeNum set to zero, the operating system initializes and caches information about the display device. When you call EnumDisplaySettings with iModeNum set to a nonzero value, the function returns the information that was cached the last time the function was called with iModeNum set to zero.

Thanks for the info. But I already tried this with the same result.
result = EnumDisplaySettings(lpdParams.DeviceName,0,&lpDMode);
where lpdParams is DISPLAY_DEVICE variable that has been populated with data returned from
EnumDisplayDevices(NULL, 1, &lpdParams, EDD_GET_DEVICE_INTERFACE_NAME);
Not sure where I am doing wrong.
thanks

Do you have some sort of loop set up for this? Something like:
int result = -1;
for (int x = 0; result != 0; x++)
result = EnumDisplaySettings(lpdParams.DeviceName, x, &lpDMode);

I have no loops for this functions. This function is called the same way I noted earlier after EnumDisplayDevices() only once.
thanks

My bad. I just assumed when _AnsHUMAN_ suggested the same thing, that your "But I already tried this..." reply meant you were using a loop of some sort.

I found out that this problem is only on Windows 7, the function ran fine on XP. Any ideas about this issue on win7??
thanks

UAC, perhaps?

UAC on my system is turned off. So, I guess its not causing the problem as the first function runs fine.

Hello Friends,
I am planning to do MCTS: .NET Framework 4, Windows Applications and I was searching for study materials or dumps. Friends kindly help me if you have any study materials or dumps for this certification.
