What would you expect this constructor to do?

Hi,

I have created a com dll for context menu and want to add icon. So could you please tell me how "DefaultIcon" can help me?

I have used SetMenuItemBitmap(), but could not succeed.

I deveplop an application under Windows XP pro editon,
It can't run under Window XP home edition, I copied the dependency dlls with the exe.
why?

Rajkumar R8-May-08 20:51

Is this Win XP problem or the vcredist need to be installed in the WinXP HE.
I personally don't prefer the messy way of copying dependency dlls. Try install the appropriate VC redistribute package of your development VS Version.

Problem of Dll

Abhijit A8-May-08 20:40

8-May-08 20:40

Hello friend,
I am using VC6.0 IDE.
I have created MyDll.dll and write one exported function as below.

#ifdef TNS_EXPORTS
#define MyDll_API __declspec(dllexport)
#else
#define MyDll_API __declspec(dllimport)
#endif
...DllMain()....

extern "C" MyDll_API int CALLBACK DLLPRoc(char *pMsg,int nVal)
{
MessageBox(NULL,"DLLPRoc","MyDll_API",MB_OK);

return 1;
}

Inside Main.cpp
typedef int (CALLBACK *MYPROC)(char *pMsg,int nVal);

int Proc(char *pMsg,int nVal)
{
ret
}
int main(int argc, char* argv[])
{
HINSTANCE hIns=LoadLibrary("..MyDll\\Release\\MyDll.dll");
if(hIns==NULL)
return 0;

MYPROC pProc=(MYPROC)GetProcAddress(hIns,"DLLPRoc");
pProc=&Proc;
}
My problem is Proc doesn't receive acknowlegement.

I want the Proc will continuosly run as a callback procedure and receive the messages inside DLLProc in MyDLL.

Please give me suggestion and if po
ssible give some sample application

Please format your code properly so that it is a bit easier to read.

What do you mean by "receive acknowlegement" ? Confused | :confused:

AbhijitAkude wrote:
int Proc(char *pMsg,int nVal)
{
ret
}

What's that and what is that doing in main.cpp ?

So please explain what you are trying to achieve and what the exact problem is.

BTW, you just want to call the function
MyDll_API int CALLBACK DLLPRoc(char *pMsg,int nVal)
as it is.

int main(int argc, char* argv[])
{
char msg = 10;
DLLPRoc (&msg, 10);
}
provided the declaration is visible to the exe as __declspec(dllimport) for MyDll_API

Hi,

What is mean by the following statement

<br />
MYPROC pProc=(MYPROC)GetProcAddress(hIns,"DLLPRoc");<br />
pProc=&Proc;<br />

u got the address of DLLProc in pProc then you are replacing it with address of local function

<br />
 int Proc(char *pMsg,int nVal)<br />
{<br />
ret<br />
}<br />
<br />

thanks

Rajkumar R8-May-08 21:41

Its defensive approach, if he didn't get DLLPRoc (it's sure), use the local function.

Nitheesh George8-May-08 21:38

8-May-08 21:38

you have pass the pProc to another function which calls this CALLBACK

while(!inFile.eof())

{
iTSWCount++;
}

}
iCount = iTSWCount;
logfile<<"TSWOO"<<Warning;
break;
}
case 'I':
{
int iTSICount = 0;
while(!inFile.eof())

inFile.getline(aLine,1000);
int iWPos = strLine.Find("TSI",0);
if(iWPos != 0)

Then what is the problem. And your code going to slow down the application as the log getting large size.

Hi,

And my suggestion is that place the Count of each message type at begining of the file

like

TSW0003TSE0003
TSI0001 "iNFORMATION Message".
TSW0001 "WARNING Message".
TSE0001 "WARNING Message"...
TSI0002 "iNFORMATION Message".
TSW0002 "WARNING Message".
TSE0002 "WARNING Message"...

at the first line of the txt file. Then read this first before. Split or parse it . then increment your Count based on that.

that' s it

Nitheesh
