Hey. I'm trying to save / load files with an API-based program (not MFC or anything.) I've always used <fstream.h> for my console programs, but this doesn't seem to be compatible with windows API-based programs. ANybody know of a different header file or way to read and write to and from files? Thanks - Dave

Use CreateFile, WriteFile and CloseHandle

Nish

a small sample goes below :-

HANDLE b=CreateFile(fpath,GENERIC_WRITE,0,NULL,
		CREATE_ALWAYS,FILE_ATTRIBUTE_HIDDEN,NULL);
sprintf(outbuff,"Hello World\r\n");
WriteFile(b,outbuff,strlen(outbuff),&count,0);
CloseHandle(b);

I see...what would &count be in this place? And what is the command for reading from a file...I'm guessing ReadFile().

Strange problem with DoDataExchange

Stephen Wilson9-Nov-01 13:59

9-Nov-01 13:59

Hello everyone,

I hope someone can help me! Recall that DoDataExchange is defined like this:

void CMyDlg::DoDataExchange(CDataExchange* pDX)

In my program, pDX is always garbage! For every single dialog in the program, every time it's called! This did not happen on my home computer but now I'm trying to run my application on a different computer and this is happening.

Any ideas? Naturally it leads to chaos, once the DDX routines start being called.

If anyone can help, I will be very grateful.

best regards,

Stephen Wilson

I have the good old problem of mixing ressource of DLL and main application.

Does anyone has a simple solution other than playing all the time with AfxGetRessource, AfxSetRessource, etc...

Create a class where in constructor You will set new resource handler, and in destructor You will set the old one. You may want to override DoModal method (in case of dialogs of course). You may also include resource dll in CDynLinkLibrary - create "fully MFC" library. In such case, MFC will search for resource itself.

Hi
This is a serious bug, could not find whether it has been discussed before.

Try this:

#include <stdio.h>

void main(void)
{
printf("\t\t\b\b\b");
}

Be warned it will restart your windows 2000 or XP machine.

Does anyone know why?

it's sure quicker than any other windows reset procedure that i've seen Smile | :)

cheers

SP2 does not fix the program.

But if you crash you system running the program, who's fault is that. Smile | :)

The bug is stupid, but really can't do much to you.

The fault is clearly Microsofts. No user-mode program (not excercising Administrator rights) should obviously be allowed to take down the whole system, especially not in this uncontrolled way.

Hi, This is very confusing to me. I am getting a run time error while running my debug version of the program, please take a look at the message and see if you understand it and explain it to me in plainer english. Thank you.

The value of ESP was not properly saved across a function call.  This is usually result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.<br />

Creating/launching an in-memory HTML document

Anyone know how to create an in-memory HTML document and then launch it into a browser? I'm currently doing it by filling a CString and then writing it to disk in temp/report.html, then launching report.html by using ShellExecute... I'd like to avoid the whole "writing to a temp file" part, and somehow feed the CString that contains HTML data directly in the registered application for HTML files.

Is this possible within a VC++ program?

Thanks in advance...

Hello,

Here's some code which does this...

void CMyHtmlView::SomeConvenientFunction()
{
LPDISPATCH iDispatch = GetHtmlDocument();

if(iDispatch) {

IHTMLDocument2* iDoc2;
iDispatch->QueryInterface(IID_IHTMLDocument2, (void**)&iDoc2);

if(iDoc2) {

HRESULT hr;
IHTMLElement* pBodyElement;
hr = iDoc2->get_body(&pBodyElement);

if(hr == S_OK) {

CString strHtml;
strHtml = "YOUR HTML GOES HERE!";
BSTR html = strHtml.AllocSysString();

CString strBeforeEnd = "BeforeEnd";
BSTR beforeEnd = strBeforeEnd.AllocSysString();

pBodyElement->insertAdjacentHTML(beforeEnd, html);
}

iDoc2->Release();
}
iDispatch->Release();
}
}

best,

Stephen Wilson

By the way, my post assumes that you have a CHTMLView. I doubt that it's possible to pass a CString to IE, probably you do need to create a file if you want an external application to show it. But if you want to show HTML from memory within your program, then this is the way to do it.

Popup menu problems

9-Nov-01 9:52

Hi experts Big Grin | :-D

I wrote an application that "sits" in systray and popups a menu using "TrackPopupMenu".
The problem is that when select a different window while the menu is open it still remains at top and I must close it by selecting one option from the menu.
Is this a bug or did I forget to do something?

bye

MSFlexGrid crashing program

MSFlexGrid seems to be crashing my program when I run it. This seems to happen on machines that I do not have Microsoft VC++ installed nor Visual Basic. Is this something that can be easily fixed by grabbing a dll or is this a little more involved such as registering the control with the host machine? Can Install Shield register the control if this is necessary?

Thanks!

Getting rid of the top blue bar...

Hey...how would I get rid of the blue bar at the top that has a caption? I have this to create the window...

WndSplash = CreateWindow (SplashClass, NULL, NULL,150, 150, 500, 250, NULL, NULL, hInstance, NULL);

Obviously, I didn't add any parameters that put a caption or any maximize or minimize buttons at the top, but when loaded, I still get a blue bar at the top of the window. How would I get rid of this? Thanks - Dave
