Always glad to help - just try to impliment what I've suggested and ask when you get stuck. I've also written a GDI+ paint program called Doodle on CP, which may help you get started in GDI+.

I'm calling the Win32 api function SHBrowseForFolder to display a Browse folder dialog. It allows a callback fn to be specified. Can anybody tell me, using the hwmd supplied in the callback is it possible to access the dialog's device context. Can this be done with Subclassing.
Thanks for reading
John

I have never used this function before, but does the HWND represent the dialog or the owner of the dialog. Anyway, you can always call GetDC to get the DC of a window. The thing that you will need to worry about is if that handle is the dialog or not. If that handle is the parent of the dialog, you can always enumerate through the windows to get your dialog handle, or cache a handle somewhere.

In theory, no, but I believe in practise it is possible to hack a solution, so long as you don't want them to float.

Hi,
We have a big monolitic (  ), project, that takes half an hour to compile ( Scassi HD, and 500 Mb. Memory), we don´t have time to chop it into smaller pieces ( now it´s not the time for that  )...
... But we have like three more computers free, so would it be possible to send to that computers a bunch of files, and that machines could compile them ? ( so if I have 400 files I could compile 50 here, 50 there, 50..., in paralel).
Does can be done on VStudio 6.0 ? And .net ? ... or that´s to good to be true ?
Thanks in advance, Greetings

Hi
i got a serious Problem with the Blocking Sockets Part of WinSock2.
A Java Applet is connecting to my TCP/IP Server (written in C++) - and now they are talking... and it works - ... but everytime the Java Applet sends a Message to the C++ the LAST BYTE doesn´t arrive. Its there when the next message is sent from the Applet - but until then.... no LAST BYTE....
does anybody know how to workaround - or WHY the H**** this is occuring ?

Do you have more information? What protocol do you use on your socket? HTTP, FTP, in-house?
If the protocol you use specifies in its header the number of incoming bytes, make sure you don't miscalculate.

I want to record sound with callback function.
I call waveInOpen, waveInPrepareHeader, waveInAddBuffer etc. successfully.
And I can get WIM_OPEN and WIM_CLOSE message in the callback function.
BUT I CAN'T get WIM_DATA message! Why???
BTW: I can get MM_WIM_DATA message when I use threads instead of callback
function, and I can get WOM_DONE message when using callback function waveOutProc.

Hey!
I found the answer.
I forget to call waveInStart.

How do i capture the whole viewport size of a CScrollView to a bitmap?...
I'm making a paint program and i want to save the whole drawing including the hidden part of the bitmap.... (the part which is not scrolled)...
I tried Bitbliting the ScreenDC into memDC which has a bitmap attached to it
but it only captured the visible part.. worst it also captured the Scrollbars...

Hi,
I am using AfxMessageBox() API in my application.Sometimes the message box doesn't come up and when I debugged and saw found that the return value is 0 which means that there is no enough memory to display the message box.What do I do to solve this problem?
Thank You.

Buy more RAM ?
I've NEVER had AfxMessageBox fail, what makes you think it's memory related ? When does it happen ?

Even for me this is the first time AfxMessageBox fails.
MSDN tells that AfxMessageBox on failure returns 0 and that it is due to no enough memory.
I forgot to mention the scenario.
This messagebox I call from within a thread function(via CreateThread) which takes as its parameter the string to be displayed and I am sure there is no problem with string passing.This I made sure by hard-coding the string just to check whether it works fine with hard-coded string value.But even in that case I got the same problem.
But now I tried using MessageBox API instead of AfxMessageBox.Its working fine.But couldn't get the reason behind the problem.
Thank You.

It's certainly an odd problem. In the future, TRACE or OutputDebugString will allow you to check a variable value in Debug mode without having to bring up a dialog.

Hi all!
I want to do next: user clicks the button, and Web Browser replaces by richedit control (in a dialog). TROUBLE: after hiding of web browser, its window handle become not valid. Here's a code:
void CCalendarDlg::OnViewEditSwitch()
{
CString strBtnText;
m_btnEditView.GetWindowText(strBtnText);
if(strBtnText == EDIT_BUTTON_TEXT)
{
m_btnEditView.SetWindowText(VIEW_BUTTON_TEXT);
m_Browser.ShowWindow(SW_HIDE);
m_wndRichEdit.ShowWindow(SW_SHOW);
}
else
{
m_btnEditView.SetWindowText(EDIT_BUTTON_TEXT);
m_wndRichEdit.ShowWindow(SW_HIDE);
m_Browser.ShowWindow(SW_SHOW);
}
}
ERROR:
Debug assertion failed here:
BOOL CWnd::ShowWindow(int nCmdShow)
{
ASSERT(::IsWindow(m_hWnd));
if (m_pCtrlSite == NULL)
return ::ShowWindow(m_hWnd, nCmdShow);
else
return m_pCtrlSite->ShowWindow(nCmdShow);
}
Help, please!

I solve the problem so:
void CCalendarDlg::OnViewEditSwitch()
{
CString strBtnText;
m_btnEditView.GetWindowText(strBtnText);
if(strBtnText == EDIT_BUTTON_TEXT)
{
m_btnEditView.SetWindowText(VIEW_BUTTON_TEXT);
//m_Browser.ShowWindow(SW_HIDE);
m_Browser.SetWindowPos(this, 0, 0, 0, 0,
SWP_NOMOVE | SWP_NOZORDER);
m_wndRichEdit.ShowWindow(SW_SHOW);
}
else
{
CRect rc;
m_wndRichEdit.GetWindowRect(&rc);
::MapWindowPoints(HWND_DESKTOP, *this, (LPPOINT) &rc, 2);
m_btnEditView.SetWindowText(EDIT_BUTTON_TEXT);
m_wndRichEdit.ShowWindow(SW_HIDE);
m_Browser.SetWindowPos(this, 0, 0, rc.Width() , rc.Height(),
SWP_NOMOVE | SWP_NOZORDER);
//m_Browser.ShowWindow(SW_SHOW);
}
}
But I'm interested in problem description... Why handle became invalid?

Is there anyway to test the DLL generated when creating a method which is to be called via CeRapiInvoke()?? I tried to a a LoadLibrary on it and don't get a handle back.
|
|
|
|

what are you trying to do exactily ?
Are you trying to use RAPI, if so you should be linking your software to 'rapi.lib' and include 'rapi.h', these come with the Handheld PC SDK. RAPI is no COM complient.

Well....I'm already using RAPI and it works fine with a PDA. What I was asking was if there is a way to debug DLLs designed to be used in conjuction with CeRapiInvoke(). I could create another DLL project and simply reuse the call but I'm trying to debug the x86 DLL generated by eVC.

ive tried both of these, and it still aint working 
//WideCharToMultiByte(0,0,_ip_name,wcslen(_ip_name)+1,tempbuf_ip,256,0,0);
MultiByteToWideChar(CP_ACP, 0, tempbuf_ip, -1, (WCHAR*)_ip_name,256);
this is my code.
char *tempbuf_ip;
WCHAR _ip_name[256];
GetDlgItemText(hwnd, IDC_IP, tempbuf_ip, 256);
//WideCharToMultiByte(0,0,_ip_name,wcslen(_ip_name)+1,tempbuf_ip,256,0,0);
//MultiByteToWideChar(CP_ACP, 0, tempbuf_ip, -1, (WCHAR*)_ip_name,256);
and then _ip_name points to:
if( FAILED( hr = CreateHostAddress( _ip_name ) ) )
{
//blah
}
CreateHostAddress points to a WCHAR*;
HRESULT CreateHostAddress(WCHAR* pwszHost)
-Thanks for any help
