Simple newbie Tab Control question

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!

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.

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??

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.

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.

Hi,

After I create and populate the my Rich Edit there is light blue Back ground when I hit enter it goes away

I was hoping the Following code snipet would solove the problem it hasn't the rich edit

is completely coverd up

C++

CDC *richdc = Myrich->GetDC();
COLORREF prevcolor, currcolor;
currcolor = RGB(255,255,255);
prevcolor = richdc->SetBkColor(currcolor);

Don't paint controls in random places, it will never have the results you want. You should only do it in response to WM_PAINT messages, which are usually handled in the OnDraw or OnPaint method.

Hi,

I don't have a message map for my rich edit so this the code for OnPaint for the Parent

Dialog

After I streamin my data the data is displayed with a thin blue background this backgrounds surrounds just this text so I when I streamin 2 lines there is blue background white line
following it.

next line of text surrounded by the blue background I am trying to get rid of blue background when I inserted the OnPaint the entire rich edit is covered up

C++

afx_msg void Show_storage::OnPaint()
 {
  CPaintDC richdc(Myrich);
  richdc.SetBkColor(RGB(255,255,255));

 }

Like I said before, you cannot just paint into a control as and when you like. You must only do it in its OnPaint member function.

Is it possible to change the background color of a CMFCButton which is under control of a visual manager theme?

Maximilien27-May-15 5:18

27-May-15 5:18

(this is partly a rant, because it seems to be something really easy to do, but the framework makes it really hard to achieve).

I need to be able to change the background color of a CMFCButton when certain conditions happen in our application.

According to the documentation, I could use the method CMFCButton::SetFaceColor (Sets the background color for the button text); but this will get overridden (sp?) by the visual manager drawing method (CMFCBaseVisualManager::DrawPushButton) and will have not effect.

Our application is under control of a CMFCVisualManager theme; so all controls are drawn to respect the current theme ( we want to have themes in our application).

There is a static method in CMFCButton to disable themes for ALL CMFCButtons; so that is a little bit overkill.

I could set the CMFCButton flag m_bDontUseWinXPTheme to TRUE (which will disable the theme for that particular button (I would need to inherit from CMFCButton) But that will change the look of the button (and if I want to keep some of the look, I would have to draw all of it manually).

Any insights, tips or hints on what would be the best way to change the background color of a CMFCButton without having to re-invent the wheel?

Thanks.

Max.

Alas, think your only solution is to derive your own button from the MFC one and change the OnDraw() method (think that's what the draw method is called, going off memory). I had to do this for a set of buttons that reflected status on their color. It's not terribly hard to do once you've done it once.

I know.

When I originally looked at OnDraw, I did not want to use it because I expected to have to redraw everything (inner, outer, fill, text and theme support)

But it ended up to look something like:

C++

OnDrawn(...)
{
   if (condition)
     pDC->FillRect(...);
   else
     pDC->FillRect(...);

   __super::OnDraw(...)
}
