Off the top of my head, I'd look at CDHtmlDialog.

ToolStripMenuItem : how to call a child frame?

sofwaidatul16-Mar-10 7:50

i am new in programming and i'm facing this problem.

i have a main frame. and i have a ToolStripMenuItem in my Main Frame. For this menu item, i put a code as below: (1example)

// loadToolStripMenuItem
//
this->loadToolStripMenuItem->DropDownItems->AddRange(gcnew cli::array< System::Windows::Forms::ToolStripItem^ >(2) {this->fromLibraryToolStripMenuItem,
this->newToolStripMenuItem});
this->loadToolStripMenuItem->Name = L"loadToolStripMenuItem";
this->loadToolStripMenuItem->Size = System::Drawing::Size(137, 22);
this->loadToolStripMenuItem->Text = L"Load..";
// ((this is a declaration))
......
((and i put the coding somewhat like below**because i couldnt find the right code))

private: System::Void fromLibraryToolStripMenuItem_Click(System::Object^ sender, System::EventArgs^ e) {
loadfromlib.h ^ openfiledialog = gcnew loadfromlib();
openfiledialog->ShowDialog();

}

when i tried to run the system; in main frame, when i click the ToolStripMenuItem, it does oppened the child frame, but it didnt work well. when the child frame is still opened, i can also click another ToolStripMenuItem as well.

i hope somebody can understand my problem and can help me solving this problem.. please, and thanks in advance...

This is a very dumb question.
Building a compiler usign the C language is really difficult (even if the 'new' language is simple). You should start reading books about compiler construction (for instance the famous 'dragon' book [^]) and consider using tools such flex and bison (see, for instance [^]).
Moreover, asking for the code 'for a new language' (what language?) is really silly.

Never expect a code from a forum, expect a help.
Compiler designing and development is a very complex activity, i don't think, it is good choice to ask about it.
Firstly learn about compiler.
I am sending some of the website that may help u understand the vastness of compiler design.

hi. i want a double cheeseburger, hold the mayo, and a lemonade. thanks. send it to this forum.

while you're at it, get all that for everyone here on the forum. and i'd also like to order blueprints for the design of a mansion. thanks.

just a word of advice, code is not part of the design, it's implementation.

Ownerdraw listview with a fixed position background image.

Hi,all.
I got a serious problem when doing ownerdraw listview with a fixed position background image in win32.
In my code, i try to use ListView_SetBkImage, but unlucky, the image itself will also scroll with scrollbar.
I also try to draw a image in NM_CUSTOMERDRAW, this can't work either, the background paints wrong.
do someone know how to solve this problem or provide some good solution?
thanks all very much for your's great help.

first i subclass my listview and handle LVM_SCROLL message with a invalidate action,it works better.
by the way, i draw the background in CUSTOMDRAW function.

Problem with parallel processing on a machine

Hi!
So I have posted this question a while back but has some additional information since I am still stuck on this problem. Here is what is supposed to happen on a server:
1) SQL Server receives request from a client
2) SQL Extended procedure launches DLL
3) Launcher DLL launches Server EXE
4) Server EXE executes Server DLL attached to it to process command

Now testing this on my environment (Windows XP Service Pack 3, Core 2 DUO @2.33GHz, 2GB of RAM) and another test server (Windows Server 2003 R2 Service Pack 2, Xeon CPU @3.0GHz, 3GB of RAM) by triggering the request event (from #1) 2x simultaneously works. The request is being handled in parallel by the server. I can see that there are different instances of Server EXE (#3) being created per request.

The problem is with another server environment that we have (Windows Server 2003 R2 Service Pack 2, Xeon CPU @2.5GHz, 3GB of RAM). No matter what happens, there is always 1 Server EXE being created (checked this through Process Explorer by Sysinternals) and for the next requests received, the machine just adds a new thread on the same existing Server EXE process (checked this through logs, GetCurrentProcessId and GetCurrentThreadId APIs). This is a problem, since there is only 1 Server EXE, that means that all threads are also sharing the attached Server DLL to it. Making the requests being processed sequentially instead of in parallel.

I have read about this and it seems to be a multi-tenant behavior on the machine but I don't know why the machine behaves that way. Anyone has any idea/clue on this problem? I'm on a dead-end right now. Thanks!

Note:
As an additional information, in Launcher DLL (in #3), here is an overview of the code being executed when called:

<br />
HRESULT hr = ::CoInitialize(NULL); //initialize COM Library<br />
.<br />
.<br />
ServerEXEPtr  ptrServerEXE; //Server EXE object instance<br />
hr = ptrServerEXE.CreateInstance(__uuidof(ServerEXEPtr)); //Create instance of Server EXE<br />
.<br />
.<br />
ptrServerEXE->ExecuteServerCommand(param); //Will call Server EXE's method<br />
ptrServerEXE.Release();<br />
.<br />
.<br />
::CoUninitialize();<br />
