Don't use NULL as the first argument to GetModuleFileName().

what can i put instead of NULL?

See here. The handle comes to you in the DllMain() function of your DLL. If you don't have access to DllMain(), you might also be able to use GetModuleHandle() to get the DLL's handle.

Most probably the statement pExplorer =Application->ActiveExplorer(); has not succeeded .
Try
if(pExplorer)
pExplorer->get_Subjet(&subject); // exception at this statement
And if the if statement failes , then rewrite the allocation code as
while(pExplorer!=NULL)
{
pExplorer =Application->ActiveExplorer();
}
These problems arise mostly in plugin codes becasue , plugin try to use the default memory allocated for the application to which this plugin is intended (here outloook exe)

Thanks For the reply.
dharani wrote: f(pExplorer)
pExplorer->get_Subjet(&subject); // exception at this statement
I am Very Sorry. I wrote the wrong statement in my question, the statement I intended to write is as follows...
pMailItem->get_Subjet(&subject);
But....
pExplorer->GetCaption();
this statment is giving the proper output..
Means there is no problem with pExplorer.
Then what is the the problem with _MailItem even sometimes get_SenderName is giving the output.
Please give me the solution.
Thanks Again for ur Immidiate Reply and Helpful suggestion...

You will have to initialize the CComQIPtr Application pointer with the object from Outlook. What I can assume from your code is that you are not initializing this pointer with the outlook object. How does your application know that it has to get an instance for outlook, so this fails and then when you do something to get the subject it causes an exception to be thrown.
you can also try debugging your application.
Try something like this. I haven't checked the code but it might help you.
CComQIPtr<Outlook::_Application> spApp;
HRESULT hr = spApp.CoCreateInstance(__uuidof(Application));
if (FAILED(hr)){
MessageBox("Unable to instantiate Outlook.","Outlook Error",MB_OK);
return 0;
}

hello
What do you do to Sql.pData[i] before callinng AddString() ?
Did you check if there are values in Sql.pData ?
Put a break point there ?
Did you verify if you have called CMyComboxClass *myCombo = new CMyComboxClass() ?

hi friend,
you already got an answer for your question, but i am having a suggestion. if you use shell functions , you need to add shell library and its platform dependent. So my idea is you to go for DllRegServer() function which is inside your COM object. Load this function, it will do your job. This method will give you the exact error report. If you use shell , you can’t. And one more thing , This method is not useful for all kind of COM dll’s suppose if you are building a Shell Extension dll, you need to use Shell API o register that dll.
thanks

use CWebBrowser2::Navigate() to display a web page.
how to know if the page is displayed properly or not?
e.g.
if the page is invalid or user doesn't connect to the internet, the page can not be displayed - in the case, I want to display a local page instead.
|
|
|
|
|
Have a look at the definition of this function and try to work around with the return types if it fails .
redindian
|
|
|
|
|
Check for Navigate_complete or Navigate2_complete and Document_complete.
Hope this will help to get when page downloaded completly.
To get knowledge of error you should check MSDN for IWebBrowser2 control.
First deserve then desire. Let be deserved first.

who can tell me what's the CALLBACK and give me some simple code. thanks
msn:Flashcutreg@hotmail.com

A callback is a function that's passed to a method by a function pointer, and which then 'calls back' to provide a hook into some aspect of a functions progress, such as providing details for a progress report.
The MSDN has lots of examples, in functions that use them.
|
|
|
|
|
A Callback is a function of which the Name and Address have been registered in a special list in the excecutable file, so that other processes can access it by name It is essentially a 'Widely Advertised Function'

Does anyone know how to find out the bounds of esp in a running program in a System way. At the moment I use something like the following for the Upper Bound:-
///////////////////////////////
static DWORD TOP_ESP=0;
void ChckStack(void){
int CharArr[4092];
__asm mov TOP_ESP,esp;
ChckStack();
}
int GetStackTop(){
TOP_ESP=0;
try{
ChckStack();
}
catch(...){
return TOP_ESP & 0x00004000;
}
return 0; //Never Happens Throw a bone to Bill Gates
}
////////////////////////////////////////////////////
This will give me the TOS! It relies on pushing the stack until it trashes,
and assumes that it is on Page Boundaries. Any more'System' ideas, or Any ideas to find the base of the stack?
regards
