Thanks for the reply, unfortunately, the link you sent didn't work Smile | :)

I'm looking for the return codes for MSDEV.EXE when calling from a batchfile.

ie: in a batch file:

msdev project name, <yadda yadda="">
if ERRORLEVEL == 1 fail, goto exit
etc
etc

If you stumble across a list, could you send it my way?

Thanks! Smile | :)

Inserting dynamic text onto graphic

stub19-Mar-03 4:49

19-Mar-03 4:49

I need to be able to take a canned graphic of a form and be able to dynamically insert text items such as name and address onto the graphic and then send the information to a printer. An example of this would be like a kid's game where the kid enters their name at the beginning of the game and then at certain points during the game, they can print out a certificate or card that has that name on it. Can anybody steer me in the right direction? I'm developing under MSVC 6.0.

Thanks in advance.

Use a static text control over top of the image and change the value dynamically as needed. You will need to overide OnCtlColor(..) and draw the background of the static control transparent.

Many thanks for the reply Art. Sounds like a workable solution that shouldn't be too cumbersome to implement.

Yes. Look up InternetConnect in MSDN and all applicable functions. It is quite easy to do.

It's called the System Tray.

There are numerous articles here on CP about how to do it.

Overriding OnCommand

I have an application with a view and a tabctrl on it. Several dll's draw there control on it. Somehow the commands for the controls (BN_CLICKED etc) are not received by the controls, if I do not overwrite the OnCommand of the tabpage. I tried it as following:

C++

BOOL CTabPage::OnCommand(WPARAM wParam, LPARAM lParam) 
{
    BOOL handled = FALSE;

    // the message was not handled by the base class, try to send the message to a control
    handled = ::SendMessage((HWND)lParam, WM_COMMAND, wParam, lParam); 
    
    if (!handled)
    {
        // message ws not handled, pass the message to the base class
        handled = CDialog::OnCommand(wParam, lParam);   
    }
	
	return handled;
}

Using this code my controls do receive their messages, but my tabpage messages (WM_KEYDOWN) are not processed anymore. There has to be a better sollution, anyone got an idea?

Enviornmental Variables

I'm changing some enviornmental variables and creating some new ones by putting the appropriate entries in the registry.

However the system doesn't seem to recognise the changes until I logout and back in again... is there anyway around this "Cacheing" programatically?

sequence of adding recs to DB

I am frustrated. It seems that my ado database adds new records at random places at different runs of the program. I need some sort of certainty here. Even MoveLAst doesnt help. I am doing an addNew() on the ado recordset....

Appreciate your help,

Look at primary key, it usually dictates where it is inserted. However you cannot rely on it ether because physical layout of the table relies on internal workings of particular database, as far as I know there is no guarantee. You can use "sort by" to get records in the order you want.

Typically they use MiniFrameWnd(?) and I don't think there is any option to remove the caption for this. The caption also provides something to grab to move the toolbar around. I think you'd need to provide your own frame wnd to do this.

Combobox dropdown showing wrong selection

Richard Jones19-Mar-03 2:49

Richard Jones

19-Mar-03 2:49

I have a standadrd combobox populated with a font's 256 characters.
When the user selects one, the list closes, and the correct value is shown in the combo line.

If the user selects a character with a double (ie 'A' and 'a'), the next
time the list drops down, the FIRST one ('A') is shown in the combo line, not the selected one ('a').

As long as the selected value is unique, there is no problem.

I have tried using OnDropDown to reset the CurSel to the proper index, GetLBText for the string, etc. and nothing works.

ShellExecuteEx & WaitForSingleObject

Brian Delahunty19-Mar-03 2:21

19-Mar-03 2:21

Hey.

Having a small problem launching an app using ShellExecuteEx and using WaitForSingleObject afterwards....

If I use WaitForSingleObject the app launches but seems to freeze until I close my program... If I don't use WaitForSingleObject then it runs perfectly fine...

C++

SHELLEXECUTEINFO ShExecInfo = {0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = ".\\J2EE_SDK_1.3.1\\setupJ2EE.exe";		
ShExecInfo.lpParameters = "";	
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL;	
if(!ShellExecuteEx(&ShExecInfo))
{
    // I'm doing somethng in here
}

// Hide window until the process returns
this->ShowWindow(SW_HIDE);
WaitForSingleObject(ShExecInfo.hProcess,INFINITE);

The program I'm launching is the setup for the Java Enterprise Enviornment [An InstallShield v 5.10 setup file.]

Any ideas???

try something like

while (WaitForSingleObject( ShExecInfo.hProcess, 0 ) != WAIT_OBJECT_0)<br />
{<br />
    while (PeekMessage( &msg, 0, 0, 0, PM_REMOVE ))<br />

        TranslateMessage( &msg );<br />
        DispatchMessage( &msg );<br />

Subclassing

Mathias S.19-Mar-03 1:24

Mathias S.

19-Mar-03 1:24

I need a class that creates the controller I need dynamically. When this class is created it loads up some data from a file and depending on what it says in that file the controller should be a CListCtrl or a CEdit.

So I thought I create a dummy controller inherited directly from CWnd let my dialog creates it and then this controller will load the data in the file and then creates the CListCtrl or CEdit and subclass it to my own controller.

It should work, but I don't get it to. I think I might have misunderstood some things with subclassing.

In OnInitDialog I have

// Created Dynamically for now
m_DummyController.create( this , CRect( x , y, w , h ) , 1 );
And then DummyController is doing its stuff (checking what kind of controller it wants to transform into)

CMyDummyCtrl::BeAEditCtrl()
{
	CEdit pEdit = new CEdit;
		
	// Should I really run this ?
	if( pEdit->create( WS_CHILD | WS_BORDER | WS_VISIBLE , CRect( x , y, w , h ) , GetParent() , 0 ) )
	{
		pEdit->SubclassWindow( this->GetSafeHwnd() );
	}
}

This doesn't work at all. I tried different versions of it so I’m properly going at this problem the wrong way. So any help with be good.

Your problem is about "scope", you've declared a CEdit variable (pEdit) inside a function, and that variable is destroyed when you leave the same function...

in order to solve it, declare your CEdit inside the class and then use it from any function in the same class, the CEdit will exist while the owner class exists too...

Hope this helps...

Re: Subclassing - Better explanation of problem

Mathias S.19-Mar-03 4:19

19-Mar-03 4:19

There where some typos in the code.

CEdit pEdit = new CEdit; // would also give a Compile error 
// It should have been
CEdit* pEdit = new CEdit;

So it was a pointer. But the problem is that it crashes in subclassWindow(...)

A better way of explaining my problem is.
I Have my Dummy controller an that controller then creates a new controller ( CEdit ) and displays it inside CMyDummyCtrl and the CEdit controller is taking up the same place that CMyDummyCtrl and all Messages sent to CMyDummyCtrl should always be relayed to CEdit since CMyDummyCtrl isn't really doing anything
That is what I want to do. And I thought I was able to do that with subclassWindow(..)
but I don't get it to work.
