write following statement at the begining of ur code
#import "msxml.dll"
this should work otherwise
try including the header file for _variant_t class too.
i.e. comutil.h

hi

i post u all the code just for ur convienece..whatever???
i did all the thing as u said..but still its giving following error:

Sorry if u felt for what I said
I just wanted to tell u that never ever post ur project code (change name of classes & DS) and post only related code.
Ok coming back to the point..
actually two weeks before i was facing the same problem
i wanted to read a xml file
& I did whatever I told u before but,
i don't know what u hv done so far & Y from the hell the problem is coming to u .
by the way I did all these things on VS2005
one more thing i would like to mention that
import the dll where u are declaring
IXMLDOMDocument* m_pIDomDoc
I mean in main frame
MainFrm.h
#pragma once
#import "msxml.dll"
class YourClass
{
public:
IXMLDOMDocument* m_pIDomDoc;
}
try this.

Hi!
Do somebody know, how to create an dynamical array?
I tried to do something like that:
int count = 0;
while (s == newName) {
int i = atoi(s);
count ++;
int arr[count];
cin >> arr[i];
}
As long, as it founds some elements in a list, it should size the length of the array and fill it.
Thanks

Replace these lines:
int arr[count];<br />
cin >> arr[i];
With this:
int* pArray = new int[count];<br />
cin >> pArray[i]
Then after you are done using the array:
delete [] pArray;

First include this:
#include <vector>
Now we'll make a typedef for a vector (essentially dynamic array) of ints.
typedef std::vector<int> IntArray;
Now he's your code rewritten to use the vector:
int count = 0;
IntArray arr;
while (s == newName)
{
int i = atoi(s);
coun++;
int num;
cin >> num;
arr.push_back(num);
}
This code look like it would get in an infinite loop to me - But that's another story.

Hello !
I tried the following in CTreeCtrl to force label edit to end when we press VK_RETURN :
GetEditControl()->ShowWindow(SW_HIDE);
but I got AssertValid failed. Is there a nother way to do so?
Thanks.

hi all..
well strange ques.
now i have a certain software and it works so fine ,but i need to add some option to a certain dialog in it !!! :-Dofcourse i don't have its src !!
any tips ??
|
|
|
|
|
No source hey. It depends on the nature of the change; If it's just a cosmetic change you can edit the dialog resource using Visual Studio. To do this you go to "File->Open", select the exe and select the open type as "Resources", from memory. It you want to add functionality you will need to alter the program or use some kind of hooking like which is possible by using the SetWindowsHookEx API - This is not for the faint hearted however.

this program downloading some files from the internet , what i want is to rename such files in a certain rules before it begin to download it
|
|
|
|
|
if u want to modify a program to yours in this way, u will not be successful because:
good software products alway have many secrets to protect themself, or dialog (such as About)/text-image on About are dynamically generated from code - not in resource.
