The first thing to think about is that you need to have a task with some progress. The common mistake people do when using a progress bar is that they put their task in the main thread and regularly advance progress on the progress bar. This is not going to work because while you are processing your task, no messages are processed which means the full UI will freeze (and the progress bar won't progress).
What kind of task are you running ? Is it a kind of computation ? If yes, is it running in a separate thread ?

He asked about separate threads.
If that was a difficulty with language, no problem. If you don't understand the difference between a method and a thread, you have a whole lotta reading to do.
Have a search for CreateThread, AfxBeginThread, PostMessage.

So what's the point in having a progress bar that won't progress? That just sounds counterintuitive. I suggest an unprogress bar instead. That way it won't matter if the primary thread is busy or not.

OK I can now process LVN_ITEMCHANGED messages in my list ctrl. Thanks for that, David Crow.
I need now to make a certain column be editable in my CListCtrl-derived class, like when you click on a file name in explorer you get an edit box. There is a flag LVS_EDITLABELS which does exactly what I want. Unfortunately it works only for the first column, and I need to edit the 3rd column. Is there an easy way to do that, or should I make my own floating edit box (with MoveWindow/ShowWindow)?

Hi to all,
Could anyone please tell me how to use setfocus (or may be any other methods) to set focus to an editbox by default. ie whenever the dialog box opens, cursor should be in the editbox.
I have variables of the edit box, but as value. not control. So I guess we can use something like
GetDlgItem(IDC_EDIT1)->SetFocus();
But its not working for me. Please help
thanks in advance

Make the edit box the first in the tab order. To do that look at Layout menu in the resource editor.

thanks for reply,
But there should be something like setfocus() right.

In case you make the edit box first in the tab order, you don't need setfocus.

Layout->Tab Order
the Layout menu appears only when you are in the dialog editor.

Hi All
I have one dll(created in c) and i have one console application(in C).Now i want to read console application variable value from dll.Is it possible please gimme ur input.
Mohan t C

|
|
Is the console application loading the dll ? If yes, why don't you simply export a function from the dll that returns the value ?
|
|
|
|
|
No,Dll calling console app variable value..
Mohan t working for N.I.C

Errr, what 
I was asking if the dll was loaded by your console application (meaning that your console app uses the dll).
So, you are saying that your dll should use a variable from your application ? You can do the same as my previous suggestion: expose a function that is called by your app and which will set the value of the variable in the dll.
|
|
|
|
|
I understand,But how do we export console app function and how do we call it from dll.
I tried _declspec (dllexport),but am unable to do.
Thanks for ur help.

Why would you want to do something like that ? This is really not a good practice. You have to keep in mind that your dll could be used not only by your application but by any other app. So, why don't you simply export a function in your dll that the application can call. By calling this function, your application can pass the value of the variable to your dll.
Anyway, what you are trying seems very strange and it seems you are a bit confused about the dll stuff. Can you explain what you are trying to achieve exactly ? Why do you need to retrieve this variable from your dll ? Maybe we'll be able to suggest a better approach.
Please bear in mind that we can't read your screen and we don't know anything about your application.

Thanks and sorry for this confusion.
Actually i want to get user input(runtime) say username and password.i couldn't do that in DLL.so i planned to use console application for getting user inputs and stored in some variable.then i will get that variable values calling from dll.

So, what prevents you to retrieve to credentials in your console application and pass them to your dll by calling an exported function of your dll (for instance checkCredentials(std:string username, std:string password)) ?
Why do you absolutely wants your dll calling your application ?
|
|
|
|

Am running a tool using my Dll.Previously we were hardcoded username and password(passing parameter) now i dont want to hardcode that.so am planning to get username and password from user itself.
So i want to display input window for getting username and password(Is this possible to do in DLL).....Is there any way?
Thanks
