The link I provided in the previous post has the steps for letting a worker thread do the work while posting progress status messages to the main dialog. That's just one of many ways to utilize a worker thread. I'm not sure a modeless dialog will solve your problem. I've learned to dislike modeless dialogs and find them rather useless and troublesome to work with anyway.
I think you'll find the worker thread is the best solution when performing a lengthy operation without "blocking" the main GUI thread.

i read the link page and im as lost now as i was before i read it as i said im new to programming and ive never had to make a worker thread so i heve no clue about how to do it or put what where.

I apologize for the confusion.
I put together a demo dialog app that simulates processing 500 files with an artificial delay in the processing loop to demonstrate the worker thread and abort button on a seperate progress dialog box. The progress box is modal but it's GUI remains responsive because it spawns a worker thread to perform the simulated processing.
I'm guessing this is what you were after.
Important areas are at the bottom of the stdafx.h and in the message maps. I tried to comment it well but you have to rememebr that it's just simulating some work in the worker thread loop so use your imagination a bit.
Anyway, I'll send you an email and if you feel the short demo will benefit you then just respond back via email and I'll zip and attach it to a reply mail. I wrote it in VC++ 6.0. I have VC++ 2003 if you for some reason can't get it to work. Just let me know if any problems and I'll convert it to 2003 and see what I need to change (if anything).

I got your reply and sent the demo.
I just realized that I never set the variable m_Title so you can just ignore any reference to it. It was just meant to allow concatenating the application title with the current progress stats in the title area.
I don't work well under pressure

Handle the WM_RBUTTONDOWN and WM_CONTEXTMENU message in the PreTranslateMessage funtion. When any of this mesage arrives, check whether the handle is of the ActiveX control. If so do not call the base class' PreTranslateMessage funtion but u show ur own context menu.

Hello!
How can I view the (optimized) Release
Assembly Code in Visual C++ 6 with debug
info - or at least with function names?
Or how can I find a special function?
I noticed that the debug code is quite
inefficient - for example redundant jumps,
even local variables are never kept in
registers, the this-pointer is moved to an
register in nearly every code-line, sometimes
several times, and so on...
Is the release code better? It speeds up
the execution (of my Raytracer) a little
bit, but not as much as I hoped.

I think you should go to Project --> Settings --> C/C++ --> Category: Listing Files --> Listing file type and select Assembly with Source Code. In this case the compiler will generate ASM files and you can investigate them.
I hope it helps.

Greetings,
I have a class with over 25 data variables that have to be set or changed regularly by the user. What, in your experience, is the best strategy to use to set them? For example, should I put a vector in the class that contains the 25 variables and search for itthem all in a vector and when the user changes one go find the specific variable and change it? Or should I just use 25 set and 25 get functions for each one? The user will pick a drop down box and choose which one they want to change. I am wondering what is the most efficient way to implement that on the back end.
Thanks in advance and I look forward to your replies.
Sincerely,
BP

i have 2 combo boxs im my project have the data added to them have the control var's
CComboBox m_takeout;<br />
CComboBox m_putin;

m_putin.SetCurSel(0);<br />
m_takeout.SetCurSel(0); in my OnInitDialog();
but it not setting the data into the edit part of the control.
anyone know why?

This code is supposed to display the first data in the combobox data item. I dun know what went wrong. Can u plz paste ur OnInitDialog() function here?
Regards,
Ram

<code>BOOL Renamer::OnInitDialog()
{
CDialog::OnInitDialog();
// TODO: Add extra initialization here
list.InsertColumn(0, "Title", LVCFMT_CENTER, 350, 0);
m_takeout.SetCurSel(0);
m_putin.SetCurSel(0);
m_takeout.UpdateWindow();
UpdateData(FALSE);
CString csTemp = BaseFolder;
csTemp += _T("\\*.mp3");
CFileFind ff;
BOOL bWorking = ff.FindFile(csTemp);
while (bWorking)
{
bWorking = ff.FindNextFile();
if ((ff.IsDirectory() && (ff.IsDots())))
{
continue;
// Recursively traverse this subdirectory
//EnumerateFolderContents(ff.GetFilePath());
}
else
{
int nIndex = list.GetItemCount();
CString m_songcount, songname, jh;
songname.Format("%s", ff.GetFilePath());
list.InsertItem(nIndex, ff.GetFileName());
list.UpdateWindow();
nIndex = nIndex + 1;
}
}
return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}</code>
that is all of it

This code is supposed to work well. if u dun get display.
Try to check for the following condition.
m_takeout.SetCurSel(0);
if(m_takeout.GetCurSel() != LB_ERR)
m_takeout.SetCurSel(0);
else
give someother value to m_takeout cbBox.

Ram

ok..
try putting
m_takeout.SetCurSel(0);
m_putin.SetCurSel(0);
as the last statement just above the return TRUE; statement.

Hello, I have received some help from earlier postings and have another question regarding the <list> class.
I have stored a list of items that are of a user-defined datatype and need a way of printing each item in the list. As shown below a struct has been defined of type data which includes 4 strings. The full program receives input by a user who types in a list of these objects of type data.
I was wondering if storing this list as a vector using a <vector> class is a better solution since I need to access each individual string per item in the vector.
Regards
HRW
#include <string>
#include <list>
#include <iostream>
using namespace std;
struct data
{ string Length;
string Sequence;
string N_Terminal;
string C_Terminal;
};

Have you tried something like this (should work for both list and vector)?
list<data> dataList;<br />
list<data>::iterator dataListIter;<br />
<br />
for (dataListIter = dataList.begin(); dataListIter != dataList.end(); dataListIter++)<br />
{<br />
printf("%s, %s, %s, %s\n", dataListIter->Length, dataListIter->Sequence, dataListIter->N_Terminal, dataListIter->C_Terminal);<br />
}
(Haven't tested it, there might be typos).

Hello, the code compiled but I did not see any output on my screen. I invoked a function called void tesings () to test out the program.
See below.
#include <string>
#include <list>
#include <iostream>
using namespace std;
struct data
{
string Length;
string Sequence;
string N_Terminal;
string C_Terminal;
};
list<data> g_DataList;
void tesings ()
{
list<data> dataList;
list<data>::iterator dataListIter;
data item;
item.Length ="test";
item.Sequence ="test";
item.N_Terminal ="test";
item.C_Terminal ="test";
dataList.push_back(item);
for (dataListIter = dataList.begin(); dataListIter != dataList.end(); dataListIter++)
{
printf("%s, %s, %s, %s\n", dataListIter->Length, dataListIter->Sequence, dataListIter->N_Terminal, dataListIter->C_Terminal);
}
}

Is it a console app or windows app?
If it's a console app, you have to drop out to a command promtp window and run your app from there to see the output.
If it's a window app, well, then you need to place the output in a windows control, like a list box or something.
Maybe try adding a few more items and see what happens. Also might try setting a breakpoint on the printf line and see if it's even getting to that point.
