I have dialog based MFC application

Oh yeah, I forgot about that, sorry Blush | :O

Well I still go back to this:

// Disable button ID_BUTTON32777 in m_ToolBar
m_ToolBar.GetToolBarCtrl().EnableButton(ID_BUTTON32777, FALSE);

// Enable button ID_BUTTON32777 in m_ToolBar
m_ToolBar.GetToolBarCtrl().EnableButton(ID_BUTTON32777, TRUE);

I'm not sure why that doesn't work for you - I just tested it in a dialog toolbar here.

Merge Modules

When using the Visual Studio Installer to create an installation, if I add a VC++ redistributable merge module (.msm) file to the solution, the installation puts the .dll(s) into the target directory.

Is there a way to have the installer put those in a subdirectory of the targetdir without having to open the .msi up with orca.exe and modifying stuff in there?

I'm trying to put those dll(s) in the equivalent of a bin directory along with my other dll(s) and ocx files.

While creating simple test multithreading application ,I am getting this bug.
I made function global.I dont want to declare static,I dont know whats wrong.

void CCustom1Dlg::OnButton1()
{
// TODO: Add your control notification handler code here
int m = 5;
CWinThread* tt;
tt = AfxBeginThread(Myfunc,&m,THREAD_PRIORITY_NORMAL,0,0,NULL);
}

UINT Myfunc(LPVOID pParam)
{
int* co = reinterpret_cast<int*>(pParam);
return 0;
}
Can anyone tell me,I searched many articles for bug,and all concludes that it must be
global or static,now I have global.still bug is pidding. My project settings are proper
for run time library.

Do you still get the error if you declare your thread proc before the call to AfxBeginThread()?

UINT Myfunc(LPVOID pParam);

void CCustom1Dlg::OnButton1()
{
// TODO: Add your control notification handler code here
int m = 5;
CWinThread* tt;
tt = AfxBeginThread(Myfunc,&m,THREAD_PRIORITY_NORMAL,0,0,NULL);
}

UINT Myfunc(LPVOID pParam)
{
int* co = reinterpret_cast(pParam);
return 0;
}

*edit* You don't want to pass &m to your thread...m can/will go out of scope before MyFunc() uses<br />
it.

Sorry,delayed responce,
If I made variable global ,written function declaration,where you shown but error is very same. No Change.

From your posts below, it looks like you fixed it, right? Smile | :)

You'll still have to make sure any variables pointed to by a pointer passed to another thread
stay in existence until all threads that use the variable are done using it!

Give this a try: (note the placement of the Myfunc function declaration before OnButton1 handler and note the use of the _cdecl modifier)

Hope this helps Smile | :)

//------------------------------------------
UINT _cdecl Myfunc(LPVOID pParam);

void CCustom1Dlg::OnButton1()

int m = 5;
CWinThread* tt;

UINT _cdecl Myfunc(LPVOID pParam)
{
int* co = reinterpret_cast(pParam);
return 0;

Did you remember to remove it from CCustom1Dlg's header file?

CE C++ - list control color and font problems

Re: CE C++ - list control color and font problems

7-Jun-07 6:25

Hi...

Here's another CE C++ question....

I have a list control. Items are listed in bolded red as added to the control. Once a user had addressed an item, I would like to change the text of that one item to unbolded black.

In CE C++ I can find a way to change the color of all items in the list control.

I cannot find a way to bold/unbold the text for only one line of the control list.

I also cannot find a way to change the font of the text for only one line of the control list.

Can any of this be done in Window CE C++? If it can be done how... any hint would be greatly appreciated.

Because the normal drawing code for list controls doesn't draw each item in a different colour you can't use the same sort of method as for the static text control. i.e. set the font, let it draw, reset the font. You need to intercept the drawing of each individual item in the list and decide whether you want it in one colour or the other.
As you're going to have to store per-item data for this anyway you might as well hold onto all the list data yourself and make it a virtual list control. There are a number of keywords you need to look for in MSDN, 'virtual list control', 'Owner Draw' and 'Custom Draw'.
I would start with Custom drawing as you probably don't want to do all the painting of the list control yourself.
Custom drawing is when the MFC control calls your functions to do parts of the painting, e.g. background or border or list item but does the rest itself.
Owner draw is where you do all the painting of the control, this is fun if you want to do something simple but list controls are not really that simple to paint.
A 'Virtual ListCtrl' is where MFC calls your functions to get each data item as it draws the list. this lets you supply the text but not the font as MFC doesn't expect it to change Smile | :)

You might be able to cheat by finding the DC for the control each time it calls you for an item and setting the font but that is bad hacking Dead | X|

In fact I didn't even suggest that Wink | ;)

CE C++ - static text font and size how to [modified]

LaCoder7-Jun-07 6:15

7-Jun-07 6:15

Hi,

I would like to change the font and size of text in static text...

I have been able to change color. here are the command lines I use to do that.
pDC->SetBkMode(TRANSPARENT);
pDC->SetTextColor(RGB(0, 0, 255));//blue

But have not found a say to set the font or font size. Is it possible to set the font size and color for a static text control in MS CE C++ (v4.0)? If it is can anyone give me a hint of how to do this?

Thanks

Two steps are needed. First you need a font, or in the case of MFC a CFont. Then you need to select that font into the DeviceContext you already have a pointer to, pDC, before the static gets drawn. I guess in the same place as you put SetTextColor, the WM_PAINT handler.
I Can't remember off the top of my head whether you call a function on the DC pDC->SelectObject(myFont) or if you can do it the other way around myFont.Select(pDC) but you'll figure that out in no time.
Remember to record the previously selected Font which will get returned when you do the SelectObject and re-select that one back into your DC after you've finished painting or you might screw up the next guys control by drawing it with your font OMG | :OMG:

Thanks for your quick reply. Between you response and the one from Anurag Gandhi think I have the changing to static text fonts handled.

As you suggested I have a lot of studying to do on these topics. I've been developing in the UNIX/LINUX environments for years. Now they throw a an MS CE C++ project on me and want it done yesterday!!!! Laugh | :laugh:

I welcome the chance to learn but it’s a challenge.

Thanks!!

To change the font face, size, weight and other properties, Create a new font and attach it with your Device context.
use following code:
CFont font;
font.CreateFont(20,0,0,0,200,0,0,0,0,0,0,0,0,_T("Times New Roman"));
pDC->SelectObject(&font);

//First parameter is Height and 2nd is width. when 0 is passed, it takes proportionate height or width.
Now you will be able to change the font size. I will suggest read more about fonts in VC++ from any tutorial.

Variable Resource Ids

I have a bunch of button resources that I want to set to be visible depending on certain criteria.
Here is a sample of the code I have:

for(i=0; i<number of sub entities; i++)
{
//for check button
pBtn=GetDlgItem(IDC_STRIPVIEW_DEVICE_1_CHECK_BTN);
pBtn->ShowWindow(SW_SHOWNORMAL);
}

I to be able to have the number in the IDC identifier change correspond to i.
How do I get the number in the IDC to be variable. Or how can I make MFC
treat a string as a resource id?

Thanks
