Basically I have huge old code with the way vc6 works. We then migrated it to vs2008. So the same old code seems to produce different results. So we are looking for some solution.

Priya Sundar

Hi, Below is the code for which i get different outputs when compiled in vc6 and vs2008. Why is it happening? Any comments will be helpful.

double x2 = 4294967036;

int i = 0;

i=(int)x2;

CString str;

str.Format(\_T("%d == %d"),i,INT\_MAX);

AfxMessageBox(str); 

Output in vc6: -260 == 2147483647 Output in VS2008: -2147483648 == 2147483647 I can see that as the value is greater than max limit, its trying to display the max value. But I guess the typecasting is not exactly working in VS2008. How to make the typecasting work?

Priya Sundar

Thanks All... by defining it as 0 and 1 its resolved.

Hi, Still it is not working after using T2A(). And fyi I am compiling my application(vc6) in UNICODE! Could you please show me your function call? The below is my function call:

CString CompletePathOfDll ="E:\\sample.dll";
HINSTANCE DllHandle = LoadLibrary(CompletePathOfDll);//loads the dll successfully

if (DllHandle != NULL)
{
int IsCorrectDll=(int)GetProcAddress1(DllHandle ,TEXT("Get_Data_Function"));
if(IsCorrectDll>0)
{
//do something
}
}

Thanks.

Hi All, I am having a common code snippet to be compiled in VC6 and in Embedded vc++(CE). Right now i am working with vc6 part.

void* CNewClass::GetProcAddress1(HMODULE hModule, LPCTSTR lpFuncName)
{
USES_CONVERSION;//for ATL, to use A2W declare this first

#ifdef \_WINCE	//for wince
	LPCWSTR lpUnicodeFuncName = A2W( lpFuncName );
	return(GetProcAddress(hModule, lpUnicodeFuncName));
#else // for vc6
	LPCSTR lpAsciiFuncName = (LPCSTR)W2A( lpFuncName );
	return (GetProcAddress(hModule, lpAsciiFuncName));
#endif

}

Problem: This function (GetProcAddress) returns 0/fails in release mode. It works fine in debug mode. General Info: The function GetProcAddress resolves to GetProcAddressA or GetProcAddressW based on the build(ascii or unicode) in EVC++ whereas in vc6, it is GetProcAddress only (simlar to GetProcAddressA with LPCSTR as second parameter). Also just FYI: http://blog.voidnish.com/?p=70[^] I tried lot of ways to typecastings.. but didnot work. Please help.

Hi, Finally were you able to find the solution. If yes please do post the same.

Hi, Thanks. I could justify my text now both horizontally and verically. The modificaiton that needs to be done in the above code to justify the text in the required rectangle is, just replace the flags in the last drawtext function by : DT_CENTER | DT_VCENTER | DT_NOCLIP.

Priya Sundar

Hi, I want to know whether it is possible to align multiple lines of text vertically and horizontally to a rectangle using the funtion DrawText. If yes, please let me know for what combination of flags, the DrawText would produce the required output. FYI flags in that funtion: DT_CENTER - Centers text horizontally in the rectangle DT_VCENTER - Centers text vertically. This value is used only with the DT_SINGLELINE value, where as my text is multiple line text. Also there is this, DT_CALCRECT - Determines the width and height of the rectangle. If there are multiple lines of text, DrawText uses the width of the rectangle pointed to by the lpRect parameter and extends the base of the rectangle to bound the last line of text. If the largest word is wider than the rectangle, the width is expanded. If the text is less than the width of the rectangle, the width is reduced. If there is only one line of text, DrawText modifies the right side of the rectangle so that it bounds the last character in the line. In either case, DrawText returns the height of the formatted text but does not draw the text. May be I need to calculate and position text myself? If yes how?
