How do I create an unmanaged Rectangle in a managed class? I'm trying,

Rectangle r2 = __nogc new Rectangle ( 0, 0, 0, 0 );

but this just gives me an error.

I'm sorry, that I don't know. But it's definately the case that you need to create one, there won't be a conversion.

Try making an unmanaged proxy function such as:

void SetBounds(int x, int y, int w, int h) {
Form->bounds = New Rectangle(x, y, w, h);
}

And call it from your managed function.

It's been a while since I used C++, but you get the idea.

Thanks guys!

Thanks guys.

Sorted the problem by passing each element individually into the bounds property like so,

<br />
System::Drawing::Rectangle* r1; // has values<br />
form1->Bounds = Rectangle ( r1->X, r1->Y, r1->Width, r1->Height );<br />

or somethng along those lines. Seems to work. Smile | :)

How?
I try do this:
case WM_NOTIFY:

switch(LOWORD(wParam))
{
case IDC_LIST:
pThis->EditLabel(hWnd, lParam);
}
break;

void IMyIEExtention::EditLabel(HWND hWnd, LPARAM lParam)
{

TVITEM tvi;
tvi.mask = TVIF_TEXT;
tvi.cchTextMax=256;
memset(&tvi,0,sizeof(tvi));
LRESULT lr;

// tvi.cchTextMax = sizeof(tvi.pszText)/sizeof(tvi.pszText[0]);

if(((LPNMHDR)lParam)->code == TVN_BEGINLABELEDIT)
{
// MessageBox(NULL, "tv", NULL, MB_OKCANCEL);
hEdit=TreeView_GetEditControl(m_hList);

}

if(((LPNMHDR)lParam)->code == TVN_ENDLABELEDIT)
{
char Text[256]="";
tvi.hItem=TreeView_GetSelection(m_hList);
SendDlgItemMessage(hWnd,IDC_LIST,TVM_GETITEM,0,(WPARAM)&tvi);
GetWindowText(hEdit, Text, sizeof(Text));
tvi.pszText=Text;
lr = SendDlgItemMessage(hWnd,IDC_LIST,TVM_SETITEM,0,(WPARAM)&tvi);
}

}

This code doesn't work. Why?

Hi!
How can i code to open a web page in a new IE windows instead of in the same IE windows like Response.Redirect? And i want the just opened web page get the authentication of the web page opening it (so doesn't need to login again)
Thanks!

Launch a new process (in .NET, that's System.Diagnostics.Process). The Windows Shell understands the IExplore command, therefore, to launch a new IE instance:

iexplore www.google.com

Here you've specified the iexplore (IE) process to launch with the argument www.google.com, making the new IE instance navigate to google. Is this what you wanted?

Hi all,

quick question. I've built a small project and I want to add a splash screen to my application. Does .net provide any splash screen components to make life easier or do I have to write from scratch?

Thanks in adavnce.

A splash screen is just a form without the title bar (Form->BorderStyle = FormBorderStyle::None), basically. Roll your own, or search CP for an existing.

LPTHREAD_START_ROUTINE related

Hello All,

I have a assignment something like this

LPTHREAD_START_ROUTINE a = ThreadProc;

Where ThreadProc is the thread function

After the above assignment a and ThreaProc shows different pointer value. Which is understandable.

My question is how do I get the ThreadProc pointer value back from a. How should my variable declaration look like

i.e if ThreadProc shows 0x00401028 in the watch window
and a shows 0x00401c90

then how do I obtain back 0x00401028 from a.

does CSoapSocketClientT keep session?

17-Jul-05 8:18

Ok. So I'm working on a web service client in unmanaged C++ which is derived from CSoapSocketClientT.
I know that when creating a web service in .Net(C#,vb,c++) one have to use (through CookieContainer property) CookieContainer class to maintain session between requestes to the server. Is there something similar for unmananged C++ web service client? Or is generated (at "add web reference.." time) code's doing it somehow magicaly on it's own?
Please help!

Solution: Invalid ResX when using ImageList (resgen.exe error)

darkzangel15-Jul-05 14:42

Only Visual C++ .NET 2003 is affected by this problem so far.

Problem:
I currently have vc++ 6.0, vc++.net 2003 and vc++ 2005 beta2 (i also got beta1). I recently having some wied error with vc++ 2005 giving out error and error about each time I was moving the mouse. I decided to try to reinstall it to fix it (it didn't). An another problem popped up just after I reinstalled my vc++ 2005 with my vc++.net 2003. When I started it an open one of my project, I was having now that error that was keeping popping :

Compiling...
Form1.cpp
Compiling managed resources...
error: Entrée ResX non valide.
error: Specific exception: TargetInvocationException  Message: Entrée ResX non valide. ---> TargetInvocationException: Une exception a été levée par la cible d'un appel. ---> InvalidOperationException: Impossible de charger ImageList.
2 error(s).
Test4 : error PRJ0002 : error result returned from 'resgen.exe'.

My windows xp is in french, it's why a part of the error is in french.

It pretty ennuing when you need to build your project and that your project is using that feature. The problem is actually in cause by some wierd problem when the compiler parse your image data in the resx file. Some syncronisation problem happen. I tried many thing like reinstalling vc++.net 2003->test failed, reinstalling vc++2005->test failed again.

Solution:
Install VC++ 2005 Express Edition Beta 2. Create a similar project. Put in the form a imagelist and bring all your picture in. Save that project somewhere. Open the file Form1.resx (Form1 is name that your given to the form) with notepad. Browse down to the location where the imagelist is. It should look like that :

<metadata name="imageList1.TrayLocation" type="System.Drawing.Point, System.Drawing, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
    <value>17, 17</value>

Copy it and go in your project in which one you have problem with the imagelist and replace the current code. Go build your project and it should work.
This is only a temp solution and you should try to completly reinstall your operating system and your vc++.net 2003.

I hope that it will be usefull to someone.

Visual C++ Different Icons for Release and Debug

you can use #if macro and check whether debug, then load the debug icon else release icon.

#ifdef _DEBUG

make use of the above #if macro and assign some variable value for debug version and for release version.

Before starting the application. Check the variable value and determine whether it is debug or release version.

Work hard and bit of luck is KEY to SUCCESS.

gcroot constructor crash

Hey there!

I'm writing a DLL as a plugin for an unmanaged piece of software, the DLL exports a struct with basic information such as name etc. There is no problem with this, it works well, other than a couple of compiler warnings that I wont go into just yet.

In my plugin, I want to use a managed class (__gc). I declare it as global like this:

<code>gcroot<COmg __gc*> Omg;</code>

Here is the class definition:

<code>public __gc class COmg
{
public:

COmg( void ) {}
~COmg( void ) {}
};</code>

This still compiles and loads fine, until I try and use my gcroot'ed class:

<code>Omg = new COmg;</code>

It dies at this line, as far as I know im linking with the .NET framework fine, because everything compiles and runs, and i've done similar projects to this in the past. I tried calling this in try/catch braces but it doesn't help.

I'd appreciate any help! Thanks.

P.S. Here are the compiler warnings that may be contributing to this?

<code>MSVCRT.lib(checkclr.obj) : warning LNK4210: .CRT section exists; there may be unhandled static initializers or terminators
MSVCRT.lib(secchk.obj) : warning LNK4210: .CRT section exists; there may be unhandled static initializers or terminators
