If you're really new to C++, you need to forget MFC and Windows, and do some console programming until you've had a chance to learn the core language properly. Do you know how to use the debugger ? Do you know what line is breaking ? Do you know if you have a connection first ?

File Transfer!!! Pett30-Oct-02 1:28 Pett 30-Oct-02 1:28  Thank you for responding. I actually have to do this for an assignment in one of my MSc classes.. Networking. So, I have no choice but to dive into everything at once.. Also, I have tried putting messages in the code to see if the program is actually reaching that part of the code... and it goes through fine... then I get the error. I'm not sure if I'm using debugger properly, but I put a break point at several places, and it went through again... then the error. I showed this to my professor yesterday, and he said it was puzzeling as well. You asked if I had a connection. You mean to the server right? Yes I do... If I am sending a file, but there is no receiving code on the server side, what will happen? I'm wondering now if it is my sending that is the problem. Maybe I'm not doing something with CArchive...

Assuming you've #included iostream and are using std::cin, it's something like int n; cin >> n; This will keep accepting input until you enter something other than whitespace.

Thanks Re: IM Client Paul Ingles29-Oct-02 14:26 Paul Ingles 29-Oct-02 14:26  It's a long time, but I think that MFC comes with a client/server chat sample, that would server as a good basis for anything like this. That's assuming you want to roll-your-own. There is code around that shows how to use the MSN protocol, so you can integrate whatever you produce with an existing service. -- Paul "I need the secure packaging of Jockeys.

I have a dialog box with a combo box that I want to fill with values just prior to creating the modal dialog box. Isn't there an easy way to do this? Thanks... (feelin pretty dumb) Re: Question, How to fill modal dialog combo box at runtime? Chris Losinger29-Oct-02 13:41 Chris Losinger 29-Oct-02 13:41  i usually put combo box inits in the OnInitDialog function. this gets hit before the dialog is visible, but after all the controls have been created. -c “If it turns out that I’m actually the one who did it, then looking for the real killers would be a big old waste of time.” -- OJ Simpson Smaller Animals Software Re: Question, How to fill modal dialog combo box at runtime? work_to_live29-Oct-02 13:54 work_to_live 29-Oct-02 13:54  That's where I'm at, but I can't figure out how to add the strings to the combo box resource created with the dialog editor. I created an array of CStrings that I load after instantiating the dialog box class, but before executing the DoModal function. In OnInitDialog I'm trying to move the CStrings into the combo box, but for an hour now, I'm not having any success. I suppose I could create the combo box and position it in the dialog in OnInitDialog, but it sure seems like there should be a easier way to do this, using the layout created in the Dialog Editor. A little more help please! Thanks. Re: Question, How to fill modal dialog combo box at runtime? Chris Losinger29-Oct-02 13:58 Chris Losinger 29-Oct-02 13:58  first, create a member variable to hold the combo box. use Class Wizard to create a variable of type CComboBox attached to the control ID (call it m_myCombo, or something) then in OnInitInstance, loop through your array of CStrings, calling m_myCombo.AddString(myString[x]) for each. -c “If it turns out that I’m actually the one who did it, then looking for the real killers would be a big old waste of time.” -- OJ Simpson Smaller Animals Software Re: Question, How to fill modal dialog combo box at runtime? work_to_live29-Oct-02 14:06 work_to_live 29-Oct-02 14:06  ClassWizard only allows a CString type as the variable for the combobox ID.

Re: Question, How to fill modal dialog combo box at runtime? Chris Losinger29-Oct-02 16:13 Chris Losinger 29-Oct-02 16:13  take a look at this article: http://www.codeproject.com/combobox/combobox_tut.asp#xx310894xx[^] -c “If it turns out that I’m actually the one who did it, then looking for the real killers would be a big old waste of time.” -- OJ Simpson Smaller Animals Software Re: Question, How to fill modal dialog combo box at runtime? work_to_live29-Oct-02 16:26 work_to_live 29-Oct-02 16:26  I give up... I Must be in another universe! This example is fine with a modeless dialog, but not a modal dialog. The function GetLBText results in an exception because the dialog window does not exist anymore whan DoModal returns. This should be so simple, but for me, it's a pain in the ... I'll figure out some other way to implement it. Thanks anyway, Later. Re: Question, How to fill modal dialog combo box at runtime?

Seems like a lot of work, but if that what it takes... that's what it takes. Here's the code that set up the dialog box... // Iterate through the doc template POSITION pos=GetFirstDocTemplatePosition(); CDocTemplate *pDocTemplate=GetNextDocTemplate(pos); pos=pDocTemplate->GetFirstDocPosition(); // Instantiate the Document List dialog class CdlgDocList SelectDoc; while(pos) { // Get a pointer to the document CDocument *pDoc=pDocTemplate->GetNextDoc(pos); // Add the document's name to the Dialog's combobox SelectDoc.AddString(CString(pDoc->GetTitle())); } // Execute the modal dialog box SelectDoc.DoModal(); // Make a copy of the selected doc name CString temp=SelectDoc.SelectedString; The AddString function loaded up a CString array in the dialog class. Then, in the dialog class, I over-road OnInitDialog, and copied the array of CStrings to the ComboBox. Then I over-road DestroyWindow, and prior to destroying the dialog window, I copied the selected string to a public CString of my dialog class. Then as you mentioned, after DoModal returned, I could retrieve the string from that public CString member. Seems like a lot of work for something so simple!!!! Thanks for the help.
