I've been messing with this application for a while now. I have an unmanaged dll that fires a few events I want to capture in my C# app.
I used a C++ managed app, found here at codeproject, that would act as an interface to my unmanaged C++ and my C# app.
I never could get it to work, so im deciding whether or not I can put the unmanaged code inside my managed code and still use my events in unmanaged code.
If this is possible I could then reference it in C# and create an event handler for those events.
My question is, what does this entail?
What about the includes in my unmanaged code?
Am I correct in thinking that include 'windows.h' can be replaced with using namespace System;?
Other includes I'm using are:
strhandle.h
string.h
stdio.h
stdlib.h
share.h
and iohandler.h
What are the .Net equivalents to these?
Also my unmanaged code uses __asm to loop through some data, is that transferable to .Net?
Sorry for the many questions, I appreciate any help one can give me.

everybody
I have a big problem,
Im using sockets to communicate 2 aplicattions,
Im using the functions send() and recv()
and everythings is going well ,,
but now I need to send a file , is a .Wav file
so the first thing I need to know is the size of the file to transfer first the size of the file , then in the other side of the connection I will know how size to receive.
well the size I get using this
FILE* f;
f=fopen("file1.Wav","rb");
int size;
fseek(f,0,SEEK_END); //move the pointer to the final of the file
size=ftell(f); //to know where is the pointer
rewind(f); //to put the pointer in the begining of the file
so I have in size the size of the file.
but this is an int var
Im trying to send the data like this
send(socket, &size, sizeof(size), 0);
so when I try to send it by the sockets it say
error C2664 cannot convert parameter 2 from int * to const char *
the function send() takes 4 param
http://msdn.microsoft.com/library/en-us/winsock/winsock/send_2.asp[^]
so,, can somebody tell me how to send the size of the file ???
Thanx
GOD BLESS YA

Hello Reu,
please modify your code something like this :-
On Sender End
char szSize[10];
itoa(size,szSize,10);
send(socket, szSize, strlen(szSize),0);
On Receiver End
int iSize;
recv(socket, szSize, strlen(szSize),0);
iSize=atoi(szSize);

maybe just like that:
send( socket, (const char*)&size, sizeof( int ), 0 );

I've got an application where I want a modeless dialog to stay on top of other applications.
When I call SetWindowPos for the main window, this window stays on top of the others but when I try the same code for the modeless it just stay on top of its parent.
The code is just basic SetWindowPos:
SetWindowPos(m_hWnd, NULL, 0, 0, 0, 0, HWND_TOPMOST);
Is there a trick or a way to make that modeless topmost ? or is it a problem from my program ?

Just a guess, but you need to make the parent of your modeless dialog be the desktop, rather
than your main window. You can se the *owner* of your dialog to be your main window...

Sure, this is a good idea. If I can't find a clean solution I will try this. Doesn't mean your solution is a dirty one, just looking for the perfect one if any

Try this instead.
SetWindowPos(&wndTopMost, 0, 0, 0, 0, SWP_NOSIZE);

I found a solution as suggested by Iain. The other ways din't work:
Here's the function that makes it :
void CfrmImg::EnableStayOnTop(bool bDesktop)<br />
{<br />
if (bDesktop) {<br />
::SetWindowLongPtr(m_hWnd, GWL_HWNDPARENT, NULL);<br />
::SetWindowPos(m_hWnd, HWND_TOPMOST, 0, 0, 0, 0,<br />
SWP_NOMOVE | SWP_NOSIZE);<br />
}<br />
else {<br />
if (::GetParent(m_hWnd)==NULL)<br />
::SetWindowLongPtr(m_hWnd, GWL_HWNDPARENT, (LONG_PTR)frmMain->m_hWnd);<br />
::SetWindowPos(m_hWnd, HWND_TOPMOST, 0, 0, 0, 0,<br />
SWP_NOMOVE | SWP_NOSIZE);<br />
}<br />
}<br />
I recall this is for a modeless dialog - don't know if it makes sense for modals.
The SetWindowLongPtr with GWL_HWNDPARENT parameter is a dirty hack. MSDN says SetParent should be used instead, but with SetParent it didn't work (I presume I have to change the windows style as suggested by MSDN - this is a later clean up work).
At the moment I'm happy with my stay on top function.
Thanks all for your assistance.

I created a dialog class CSchDlg derived from CDialog. The dialog box has a few buttons(radio and checkboxes also) and a list box. Using the class wizard i created member variables of type CButton for all the buttons and of type CListBox for the list box.
Inside the OnInitDialog() i tried the following.
Say m_ctrlButton1 is of type CButton and is the member variable for the radio button with the ID IDC_RADIOBUTTON1
<br />
m_ctrButton1.SetCheck(BST_CHECKED);<br />
The above stmt produced error.
So i changed it to
<br />
CButton *pButton;<br />
pButton = (CButton *) this->GetDlgItem(IDC_RADIOBUTTON1);<br />
pButton->SetCheck(BST_CHECKED);<br />
... and it worked fine.
I tried the same thing for the ListBox also.
<br />
CListBox *pListBox;<br />
pListBox = (CListBox*) this->GetDlgItem(IDC_LISTBOX1);<br />
... but it produced Access Violation Error
What could be the reason?
Why do i have to use GetDlgItem() to set/enable or do anything on the buttons inside the OnInitDlg() but neednt do it in other functions?

Perhaps it only appeared to work?

Are you trying to do this before CDialog::OnInitDialog() is called?

You don't. GetDlgItem() is rarely, if ever, needed.

DavidCrow wrote: Are you trying to do this before CDialog::OnInitDialog() is called?
I have tried both, b4 and after
I am restating my problem and i will try to be as clear as possible.
Aim is to have the dialog box pop up with a few checkboxes and radiobuttons checked and the listbox be filled.
Using class wizard i assigned the following member variables to the radiobuttons and the list box.
The first radiobutton is IDC_RADIOBUTTON1
The second radiobutton is IDC_RADIOBUTTON2
The listbox is IDC_LISTBOX1
When i open the MemberVariables tab in the ClassWizard i get the following..
ControlIDs Type Member
IDC_RADIOBUTTON1 CButton m_radio1
IDC_RADIOBUTTON1 CButton m_radio2
IDC_LISTBOX1 CListBox m_listbox1
Now when the dialog opens i want hte first radiobutton to be checked, the second radiobutton be disabled and the listbox be filled with certain text.
To achieve the above result i wrote the following code inside the OnInitDialog function.
<br />
m_radio1.SetCheck(BST_CHECKED);<br />
m_radio2.EnableWindow(FALSE);<br />
m_listbox1.AddString(BUFF);<br />
The above code gave the Debug Assertion Error i mentioned in the beginning of the post.
Now i change the above piece of code to
<br />
CButton *pButton;<br />
pButton=(CButton*)this->GetDlgItem(IDC_RADIOBUTTON1);<br />
pButton->SetCheck(BST_CHECKED);<br />
pButton=(CButton*)this->GetDlgItem(IDC_RADIOBUTTON2);<br />
pButton->EnableWindow(FALSE);<br />
..... it actually worked
Then i added the GetDlgItem for te list box
<br />
BOOL CSchDlg::OnInitDialog(){<br />
CDialog::OnInitDialog();<br />
CButton *pButton;<br />
CListBox *pListBox;<br />
pButton=(CButton*)this->GetDlgItem(IDC_RADIOBUTTON1);<br />
pButton->SetCheck(BST_CHECKED);<br />
pButton=(CButton*)this->GetDlgItem(IDC_RADIOBUTTON2);<br />
pButton->EnableWindow(FALSE);<br />
pListBox = (CListBox *)this->GetDlgItem(IDC_TIMETABLELIST);<br />
pListBox->AddString("Hope this works");<br />
<br />
The DoModal() of the Dialog box is done from another class CMySch.
The above piece of code works fine when i DoModal() for the first time.
But after i close the dialog and then again call DoModal from CMySch the following error:
Access violation
comes at pListBox = (CListBox *)this->GetDlgItem(IDC_TIMETABLELIST);
Inside the debug window the following was displayed
Name Value
---- ------
this {SchDlg 0x20383738 hWnd=???}
Hope things are clear
