You can read your values with CString class and then use of CString::Foramt or itoa.

I have listview in recordview mode . I want to move the position of the
row up and down the in the list view like in vc++ includedirectory path . where we can
easily move up and down the various include path . for which I am using two buttons one
for up and one for down.how it is possible.

To move an item up, call GetNextItem(-1, LVNI_SELECTED) to get the index of the selected item. Call DeleteItem(nIndex). Call InsertItem(nIndex - 1) to insert the item back in the list control.

Hi,
I created an dialog application in SDK. Dialog does not contain any control. I tried to capture WM_KEYDOWN message, but not receiving this messaage. In MFC I can track this message in PreTranslateMessage but I do not know how to track in SDK. Any Idea please.
Thanks

Hello everybody,
I have a situation when a String in a file represent a method of a especific object and i need to call it after the "A" was sent for this object.
Exemplo:
In file -> A=[B]
In C++ header -> int B(void)
In C++ CPP ->
a) Find "A" in a file and receive a "B"
b) How can i call the method "B" ????????
Sorry, by poor english. I´m from Brazil and i need study more this language ...
Tank for your help !

Hi experts,
I have a VB form that calls a "C" function (implemented in a DLL) to draw the text on the VB form. The VB form sends the window hDC, text position, font name, font size and the chinese text
I have taken analysis from an article in Code Project and created the following "C" function to take the inputs from VB and draws the text on the VB windows. Please see my "C" function below
#include <windows.h>
#include <stdio.h>
#include <tchar.h>
HFONT m_hFont;
LOGFONT m_LogFont;
_TCHAR m_szSection[256];
_TCHAR m_szEntry[256];
void DefaultFontInit();
HFONT CreateFontLocal();
long
__stdcall
CodeProjectDrawText(
long lWindowDC,
_TCHAR *lpszFontName,
long lFontSize,
_TCHAR *lpszMultiByteText,
long X,
long Y)
{
long nFontHeight = 0;
long nLen = 0;
long nStatus = 0;
_tcscpy(m_szSection, _T("Settings"));
_tcscpy(m_szEntry, _T("Font"));
nFontHeight = - MulDiv (lFontSize, GetDeviceCaps (GetDC (0), LOGPIXELSY), 72);
DefaultFontInit(lpszFontName, nFontHeight);
SelectObject(lWindowDC,m_hFont);
nLen = _tcslen(lpszMultiByteText);
nStatus = TextOut(lWindowDC, X, Y, &lpszMultiByteText, nLen);
return (0);
}
void DefaultFontInit(_TCHAR *lpszFontName, long nFontHeight)
{
HFONT hFont;
// define the logical parameters for the default font
//m_LogFont.lfHeight = -11; // size 8
m_LogFont.lfHeight = nFontHeight;
m_LogFont.lfWidth = 0;
m_LogFont.lfEscapement = 0;
m_LogFont.lfOrientation = 0;
m_LogFont.lfWeight = FW_NORMAL;
m_LogFont.lfItalic = 0;
m_LogFont.lfUnderline = 0;
m_LogFont.lfStrikeOut = 0;
m_LogFont.lfCharSet = 0;
m_LogFont.lfOutPrecision = OUT_STRING_PRECIS;
m_LogFont.lfClipPrecision = CLIP_STROKE_PRECIS;
m_LogFont.lfQuality = DEFAULT_QUALITY;
m_LogFont.lfPitchAndFamily = FF_SWISS | VARIABLE_PITCH;
//_tcscpy(m_LogFont.lfFaceName, _T("Lucida Sans Unicode"));
_tcscpy(m_LogFont.lfFaceName, lpszFontName);
// create the associated font
hFont = CreateFontLocal();
}
HFONT CreateFontLocal()
{
HFONT hFont = CreateFontIndirect(&m_LogFont);
if (hFont == NULL)
{
// GetLastError(); can be used to understand why the font was not created
MessageBox(0, _T("Impossible to create font\n"), _T("My Sample"), 0);
}
// don't forget to delete the current font
if (m_hFont != NULL)
{
DeleteObject(m_hFont);
}
// store the font (event if the creation has failed)
m_hFont = hFont;
return hFont;
}
It appears to draw something but the content is not correct. It looks like a wrong chinese is getting displayed.

Hello  the result is that say I type in a Chinese character with a certain combination of english letters through the IME keyboard, the result is that the Chinese character which is displayed is completely different. It is not the same Chinese character that I typed in originally  But the same function works in VB. So I am not sure what else is the difference between my C function and my vb function. Need advice and help on this strange problem
Many Thanks.

I think you need to multilangue on your program and codeproject has some articles about it.

Please look at the posting guidelines again, especially the use of the pre tag to make code readable.
Before I gave up reading your code, I noticed at least one error.
You call default DefaultFontInit, then use m_hFont. But in defualt font init, you fill m_LogFont, and create hFont - so m_hFont is not inialised. I gave up after that.
For further diagnosis, please initialise all your variable to NULL, single step through, and check the state of variables as you use them / as you expect them to change. This will show things that you expect to happen not-happen. And vice versa.
Iain.

So my logic is that VB is basically an exe application that just contains a textbox on a form. It then calls "CodeProjectDrawText()" function which is written in C code (an C dll) to draw Chinese character on the VB form. So the key is that my TextOut() api in C code is actually drawing the Chinese character out. Just a note, please don't get confused with the TextOut() api being just ASCII, it is really unicode TextOutW(). In my C project settings, the unicode flag is already set, so during TextOut() it is actually calling the TextOutW() instead of just TextOut().
I have tried by calling the same TextOutW()function in VB (writting this whole small app in VB instead of C)and it works fine, but because this drawing feature has to be in C code, I can't do this in VB
Thank you very much Iain for your suggestions, Your suggestions for "m_hFont is not inialised" makes sense, so I changed the order of the code just a little by moving the "_tcscpy(m_LogFont.lfFaceName, lpszFontName);" after "hFont = CreateFontLocal();" call... but my result is still the same.
I actually stepped through the code couple time already I monitored all the variables such as "lpszMultiByteText", "lpszFontName" and so on... all seems to be correct right before the TextOut()api. Well at least in memory they seem to be correct. When I watched the 2 variables in memory stack they all appear to be correct. I mean I see my selected font name, Chinese text that I entered. But after TextOut() I see other wrong Chinese character or garbage being displayed. So somewhere fonts or code page is still not sinked up. Anyway thanks for all the good imput guys!

Hello,
I'm looking for a way to check if a DLL is currently registered. I've found code to register one, namely regsvr32 in a shellexecute, or just using LoadLibrary, but nothing to find out if my DLL is already registered.
I could search the registry, but for time reasons I'd like to avoid this. Registering the DLL each time the application starts isn't an option because the user's machine permissions aren't known and have a good chance of being very strict.
Any suggestions are greatly appreciated.

My project is C#, and i am using pinvoke for LookupPrivilegeValue.
For my test part i have enum all possible privleges on LookupPrivilegeValue.
When it came to SE_DEBUG_NAME, my Kaspersky Internet Security said:
"Project Name" belongs to group 'Low Restricted' is trying to set debug privileges.
I didn't even used AdjustTokenPrivileges
And I have API that was denied to run due to restriction, now it works. When i read SDK, this shoudnt happend. I am using XP SP3

When creating Doc/View MDI apps to have a file extension using the wizard, Visual C++ 6.0 and 2008 apps reuse the existing application when double clicking on multiple data files with the apps associated file association. The results appear the same for both "%1" and "/dde" appended to the end of the "command" key in the registry file association entry for the "open" verb for that file type.
However, the same type of app created using Visual C++ 2003 does not always behave "correctly" (assumes double clicking a document should open in the applcation instance or in a new instance if the applcation wasn't already running)
When the registry entry for the open verb contains the following text in the "command" keys default text...
"%1" works when double clicking document without app running. Fails with app running.
"/dde" does not open document when double clicking without app running (I get an instance of the app in task manager but I can't interact with the app on the desktop). Fails with app running.
Does anyone know what the trick is to get the file verbs and/or dde commands working with a Visual C++ 2003 Doc/View MDI application?
***************************************
Update:
It turns out I didn't have Visual Studio 2003, Service Pack 1 installed on this box I'm compiling with. This issue was specifically addressed as the OnDDEExecute() not getting handled correctly.
Stupid me.

What's your problem than using EnableWindow( FALSE )?

Call EnableWindow function of the CButton class.
