Can anyone help me in developing a small application?
I'm stuck in the module in which I need to search the whole drive for the installation of a .exe file.

Are you familiar with the _findfirst()/_findnext() pair?

i'm not familiar with findfirst stuff.
Can you please elaborate?
I was trying to use boost libs.

See here. Examples on the Net and here at CP are almost limitless.

If you are looking specifically for "installed" programs (rather than just any and all exe files), you could use WMI with the Win32_Product class. It's a tad more code, however, with all of the COM involved.

no, I'm don't want to use pre-developed apps.
btw, I'm trying to dev the following, but till now no success.

small utility - no GUI.

cfgdump.exe

1) needs to search drive and find where an exe has been installed (customer can install it in multiple places).
2) goes to directory and confirms existence of some files.
3) runs some commands through a spawned process
4) the commands from item 3 will produce a file.
5) you will need to zip up the contents of the file using https://code.google.com/p/miniz/ library
6) Ask the user for a password
7) encrypt the file using http://www.cryptopp.com/ library

File needs to be statically linked and highly portable.

So you are looking specifically for "installed" programs, yes?

Of the eight steps you mention, what do you have done? You've at least started, haven't you?

I shared an example for iterating files and folders here. It does not do anything useful, so you'll need to fill in the blanks with your specifics.

I'm getting more and more confused.
From the morning, I'm reading about boost libraries and then something else.
I haven't started coding yet.
But, I do want to start as soon as possible.

So I assume you saw this? It's not an isolated example.

Simple newbie Tab Control question

2-Jun-15 7:27

Did you include the windows.h and iostream header files? Did you remember to use the std namespace?

Hello,

I've implemented a simple SDI program with MFC and a tab control used to select a child window from a set of 3 dialogs.
I followed the instructions at this link:

http://www.codersource.net/2010/01/30/ctabctrl/

Everything works if I put the handler of TCN_SELCHANGE in the view class.
Instead If i put the handler in the CTabCtrl derived class of my tab control the handler is never called when I push tabs and the tab control doesn't work

Can anyone explain me the reason?

Creating GUI on existing in VC++ 2010 project

Hi guys!,

I'm developing an application using a library in VC++ 2010. I don't have previous experience in GUI programming. So I'm wondering how to begin with on my existing project.

It's an tracking experiment where I need to set various parameters initially for the specific task in GUI.

Once I set all parameters, GUI have to create a file containing all those parameters and have to pass to the project.

It would be of great help if you could give feedback,

Thanks!

Richard MacCutchan1-Jun-15 0:43

I am not sure exactly what feedback you are expecting, as it really depends on what sort of GUI you wish to present to the user. Setting parameters could be anything from simple text input, drop down list or combo, slider, up/down control etc., all of which can be accomplished by using the various Windows Controls[^]. I would suggest looking at some of the sample articles here on CodeProject[^] to get some ideas about how other people have approached similar issues. You could also add some more detail to your question which would help us make more suggestions.

Thank you!
Sorry about my poor explanation!,
The working on a project which is windows console application. But as per my understanding, GUI can be only done in 'Windows Forms Applications'.
Will it be possible to change console applications to windows forms application, where I can find all tools for creating GUI??

Richard MacCutchan1-Jun-15 2:31

1-Jun-15 2:31

Windows Forms applications use C++/CLI or C#. But you can create a Win32/MFC Windows application using the standard Windows controls. Since you already (I assume) have most of the code in your console app, converting it to Windows should not be too difficult (depending on your skill level), although the initial learning does take some time.

You can create a basic Windows application from the template supplied with Visual Studio, so it is worth starting with that to see how it is put together.

Thank you!.

I have been trying to convert my console application to windows form application.

While running I'm getting an error, following is the part of my main function..

C++

int main(array<System::String ^> ^args)
{

   Application::EnableVisualStyles();
   Application::SetCompatibleTextRenderingDefault(false);

<pre>
char fname[30];
char fpath[100]; // file name for logging
char fpath1[100]; // file name for logging

//disable force field for first half of trial 
for(int i=0;i<NTRIALS/4;i++)
    //force_enable[i]=true;
    force_enable[i]=false;
for(int i=NTRIALS/4;i<NTRIALS;i++) </pre>

This was the error. I tried changing 'main' as 'WinMain' but it's not preceeding

error LNK2019: unresolved external symbol _WinMain@16 referenced in function ___tmainCRTStartup

any suggestion greatly appreciated.

Richedit getting blue background when Gaining focus SetSel(0,0) in ON_EN_FOCUS solved problem !!!!

8-Jun-15 22:51

Your code above is using managed C++, not ordinary Win32. I suggest you start again and either create a proper Windows Forms application, or use standard unmanaged C++ or MFC.

Sorry for starting a new post but the problem with the blue background around the text happens when the richedit or parent Dialog Gains focus

Any help appreciated

is completely coverd up

C++
