Hello,
here is my problem; using the GDI+ i draw a string using DrawString() and i draw a rectangle around this string.
But when i scale the view (to simulate a zoom in or zoom out) the string can becomes larger than the rectangle !
It seems that the true type fonts are not truly scalable.
However i read that the GDI+ subtly manipulates the character and word spacing...
Can you help me ?
Thanks a lot.

Hi ! 
Did you try to modify the unit parameter in the Font class constructor ?
|
|
|
|
|
Yes, no effects... sorry... 
|
|
|
|
|
How are you using the scale ? Are you using an API method ?
|
|
|
|

here is the code used;
void CChildView::OnPaint()
{
CPaintDC dc(this); // device context for painting
Matrix myMatrix;
myMatrix.Translate(m_cx / 2.0f + m_fOffsetX, m_cy / 2.0f + m_fOffsetY);
myMatrix.Scale(m_fZoom, m_fZoom) ;
graphics.SetTransform(&myMatrix);
// Create a string.
WCHAR string[256];
wcscpy(string, L"These days, products with VIA's new PT880 and the SiS 655FX are becoming available");
// Initialize arguments.
FontFamily fontFamily(L"Arial");
Font myFont(&fontFamily, 14, FontStyleRegular, UnitPoint);
// the hardcoded coords come from MeasureString();
PointF origin(-753 / 2.0f, 0.0f);
SolidBrush blackBrush(Color(255, 0, 0, 0));
Status status = graphics.DrawString(string, (INT)wcslen(string), &myFont, origin, &blackBrush);
RectF boundingBox;
graphics.MeasureString(string, (INT)wcslen(string), &myFont, origin, &boundingBox);
// Get the height of myFont.
REAL height = myFont.GetHeight(&graphics);
wcscpy(string, L"et blablabla...");
origin.Y += height;
status = graphics.DrawString(string, (INT)wcslen(string), &myFont, origin, &blackBrush);
// here we draw a rectangle around the text, the values come from the initial MeasureString()
// Create a Pen object.
Pen blackPen(Color(255, 0, 0, 0), 1);
// Draw the rectangle.
// the hardcoded coords come from MeasureString();
graphics.DrawRectangle(&blackPen, -753 / 2, 0, 753, 23);
}

How exactly are you doing the scaling? If you use the ScaleTransform (or whatever it's called) it should work without incident.
Joel Lucsy - You can have it done cheaply.
- You can have it done well.
- You can have it done fast.
Pick any two.

I'm trying to build a utility that runs a few console commands and directs the output to an edit control.
i.e. Click a button, it copies some files, and the output of the xcopy command shows up in an edit control.
Another desired result (for an entirely different project down the road) - is to be able to interact with the console application. (end user can give input as needed to the application)
It seems like a fairly easy thing to accomplish (fingers crossed), but I'm having a hard time finding sample source code to work from.
Can you point me in the right direction?
===
The workflow that I'm trying to implement is as follows:
1. Copy files from e:\tiff to c:\clients\$customer name$\tiff
2. Convert images from tiff to jpg (I can do this via command line, requires command line parameters - meaning c:\convert.exe /s:conversiontemplate.txt )
3. Create thumbnail size images (also via command line)
4. Create html for web photo album
5. Copy other files to directory for CD-ROM (autorun.inf, drive.ico, etc.)
6. Upload html docs, images to web server. (using dundas tcp-ip)
I want to put these commands in an MFC app so that my receptionist can just click a button and have all the magic happen. I want the output in an edit control so that if there is a problem, the receptionist can copy/paste the output into an email and have me troubleshoot the process.
(Maybe even have a send-to-steve button that handles that part)

Take a look at the MSDN article Q190351, and the one titled "Creating a Child Process with Redirected Input and Output."

Thank you. That is the perfect starting point for me!

hi,
i want to disable the possibility to change the label of an item of a CTreeCtrl. SetReadOnly() namely makes it possible that the user can't edit the item's label, but the edit control box is still displayed and that shouldn't happen.
Any ideas ?
Thanks in advance!

I got it. Maybe someone is interested in how i did it, so here is the solution. If the message TVN_BEGINLABELEDIT is send, i dispatch the follwoing notification: SendMessage(TVM_ENDEDITLABELNOW, (WPARAM) (BOOL) TRUE, 0);
Looks simple, isn't it?!

Handle TVN_BEGINLABELEDIT, returning TRUE to prevent editing.

What is the simplest way to kill an MFC dialog based application?

alt+F4 works pretty well.

Find the handle of the window (FindWindow or EnumWindows work well), then send it a WM_CLOSE message.
If this causes it to ask to save data, and you don't want that, use DestroyWindow instead, although this is very brutal.

I am having a problem using the CEdit class and the CRgn class. I am using the CRgn to make a roundedrect and then setting the region to the CEdit control during PreSubClassWindow ( I am actually trying to make a class that is derived from CEdit that is a rounded edit control ). However it seems that the region is only having an effect on the border of the CEdit. The white part ( the part you type in ) is still a rectangle. Any Ideas why this is happening?

Friends,
I have a vector of pointers:
vector< PhoneRecord*> phonerecs(MAX);
I want to pass this vector to a function so I can add things to it outside of main().
The function declartion is:
void addPhoneRecord(PhoneRecord* records[]);
and call it from main() using something like:
addPhoneRecord(phonerecs);
The error I'm getting is:
error C2664: 'addPhoneRecord' : cannot convert parameter 1 from 'class std::vector<class PhoneRecord *,class std::allocator<class PhoneRecord *> >' to 'class PhoneRecord *[]'
I understand I'm not passing this correctly...
I'm sure this is a somewhat easy solution, but I can't seem to pinpoint it.
Thanks in advance!

Dave, thanks again for your quick and informative reply.
Allow me to include better code representation:
My function definition is:
void addPhoneRecord(string& name, string& address, string& phone, PhoneRecord* records[])<br />
{<br />
Name* nameEntry = new Name();<br />
nameEntry->set_name(name);<br />
Address* addressEntry = new Address();<br />
addressEntry->set_address(address);<br />
PhoneRecord* phoneEntry = new PhoneRecord(nameEntry, addressEntry);<br />
phoneEntry->set_phoneNumber(phone);<br />
<br />
records.push_back(phoneEntry);<br />
}
When I call it from main I'm using:
addPhoneRecord(name, address, phone, &phonerecs.back());
All of the setting functions and the like work like they should, and properly.
The error I'm getting is:
error C2228: left of '.push_back' must have class/struct/union type
If I comment out the records.push_back(phoneEntry); it compiles fine, but I get the standard WinXP error report problem.
Any suggestions?
Thanks again.

Since you are actually trying to use the vector as a vector (instead of just an array as you indicated in your previous message), you should pass a reference to the vector into the function. The last parameter should be: vector< PhoneRecord*>& records - then you will be able to use the push_back member.

Dave,
Thank you again. You're a master.

My program uses API calls and now that I have converted my program from a simple console app to a windows service, I cannot use all of the same API calls. If anybody is familiar with this type of problem, please fill me in with possible fixes. Thanks!

A little more information would be useful here...
What do you mean when you say that you cannot use all the same API calls? Is it not compiling? Or not running? If it isn't running, what error is produced? What APIs aren't working?
