You've removed resource.h from project *and* from disk as well?

yep again

This is what I did:
- created the resource dialog using resource editor inside vc6
- build the resource
- closed the workspace
- opened .rc-file in external editor
- changed all the references pointing to resource.h (2) to else.h
- copied the definitions to else.h
- opened the workspace again
- rebuild the whole thing

... works just fine Big Grin | :-D

I've changed all the references inside the rc-file to another header file and guess what ... It works!!! Cool | :cool:

Copy of files from one folder to another

The question remains: Why do you want to do this? Anyone else maintaining your program will want to find the resource symbols, and will look for resource.h. Another problem with this is you will be tempted to put other symbols or definitions in else.h (treating it like any other header file). DevStudio tends to get cranky when resource.h (or whatever you've named it) contains anything in it other than the stuff it puts there.

I'm not meaning to sound critical, this is just the voice of experience.

Can anyone tell me about a simple function that copies all files from one folder in a remote location to a local folder?
For example:
Move all files located in \\Remote\Folder to c:\localfolder
Thanks!

Form Scrolling Problem

RuiSantiago26-Sep-02 5:53

Hi, for 3 days i'm trying to make my form resizable.

Well, in desing mode, as my form has the VScroll property true, i increase the bottom of the form and then when i run it the scrollbar appears and works.

I want to do that but by code, to increase the form's bottom as i'm going to dinamically filling it with objects, i'm doing like:

CRect myRect;

for (int i=0;i<100;i++)
{
caramba[i] = new CStatic;
g.Format("%d", i);
caramba[i]->Create(g, WS_CHILD|WS_VISIBLE|SS_CENTER|WS_BORDER, CRect(10, i*10, 120, i*10+50), this);
myRect.bottom+=20;
}

MoveWindow(myRect.left, myRect.top, myRect.right, myRect.bottom);
this->GetParentFrame()->RecalcLayout();

The objects are drawn in the form until number 65, well until the regular size of the form, and the scrollbar do not appear.

How can i make the VScrollbar to appear as the form size increases?

Thank you in advance

I think you need to set the scroll size. Try this function:

SetScrollSizes()

Thank you Lucy, i tried your suggestion, i did like:

CRect myRect;
CSize mySiz OMG | :OMG:

e;

this->GetClientRect(&myRect);
mySize=myRect.Size();

for (int i=0;i<100;i++)
{
caramba[i] = new CStatic;
g.Format("%d", i);
caramba[i]->Create(g, WS_CHILD|WS_VISIBLE|SS_CENTER|WS_BORDER, CRect(10, i*10, 120, i*10+50), this);
myRect.bottom+=20;
}
MoveWindow(myRect.left, myRect.top, myRect.right, myRect.bottom);

this->GetParentFrame()->RecalcLayout();
this->SetScrollSizes(MM_TEXT, mySize);
this->ShowScrollBar(SB_VERT, TRUE);

this->SetScaleToFitSize(mySize);

Even using SetScrollSizes and ShowScroll after RecalcLayout, it apears for half a second or something, and then disapears again.

I tried SetScaleToFitSize and it did not improve

Why does this appends?

Thank you in advance

I am not sure. But I think you need to give the total size to SetScrollSize. that is, the size of your document.

Excuse me for my poor English, let me give you an example.

Say you are opening a document which will occupy a 800x600 screen. But your window is only 400x200 big. So you set the scroll size to be 800x200. And the vertical scroll bar and horizontal scroll bar will appear for your to scroll to see the other part of the contents.

If you are using this->GetClientRect() to set scroll size, you are telling Windows that the screen needed is of the same size as the screen allocated. So, no scroll is necessary.

Hope this helps.

how to terminate a dll?

ns26-Sep-02 5:36

26-Sep-02 5:36

I want to have a cancel button for a progressbar which pops up on its own window. This is to cancel the operation. I read about peeking in the message queue etc. What I want to do when I get the ID_CANCEL message, is to terminate the process which is happening within the dll. WHats the way to do this termination? Do we notify the dll which then disposes of itself ? Or can we externally "kill" the dll?

Thanks,
ns

Re: how to terminate a dll?

26-Sep-02 6:15

I'm not sure what you're trying to do here (multi-thread?) but you can always unload a dll with the same handler you received loading it.

using: [VISUAL STUDIO 6.0] [WIN98/2]

ns26-Sep-02 6:22

26-Sep-02 6:22

No, its single threaded. except that my dll does a lengthy process, and I am trying to avoid the hassle of notifying it that a CANCEL was received (Its a VB dll) So I was thinking that I could kill it from outside> but I guess it has complete control till it finishes, so I'll have to send it a message to interrupt it. Not fun since the dll is in VB and the sender is VC app. VB cant take user defined messages...

Thanks,

How can VC++ setup DrawText with TabStop with 7 character & DT_EXPANTABS?

26-Sep-02 6:32

There's no difference between .dll and non-dll code in respect to your problem. You just need kind of a communication channel between the time-consuming process in .dll and part implemented in .exe. Sort of callback, perhaps.

Hi,

I have used the following to print out my text & tabs, it has worked fine!

<br />
  dc.DrawText(Text, CRect(x, y, x + Info.m_rectDraw.Width(), y + csText.cy), DT_EXPANDTABS) ;<br />

*)But because I need some special spacing (in-line) ... I would like to reset the Default TabStop from 8 charcaters down to 7! I try the follwing but it does not work! (set high order byte in nFormat = 7)

<br />
dc.DrawText(Text, CRect(x, y, x + Info.m_rectDraw.Width(), y + csText.cy),  (0x0700 |DT_EXPANDTABS)) <br />

<br />
dc.DrawText(Text, CRect(x, y, x + Info.m_rectDraw.Width(), y + csText.cy), (0x0700 | DT_TABSTOP));<br />

Anyone knows why or how to do it?

Many thanks for any help!

Use TabbedTextOut(), you can specify the tab size.

Re: where did you get this (0x0700 | DT_EXPANDTABS) stuff?

26-Sep-02 5:18

Use DrawTextEx. You'll be able to pass tab size in DRAWTEXTPARAMS struct (iTabLength field).

BTW: where did you get this (0x0700 | DT_EXPANDTABS) stuff?

Hi Tomasz,

Thanks and I will try ... but I do not think it is easy for me to do your suggestion (I am not very good in DrawText commands) ... might be you can help a bit more detail?

*) The (0x0700 | DT_EXPANDTABS) I did, because I read in CDC:DrawText command specificatons:

===========================================================================
int DrawText( const CString& str, LPRECT lpRect, UINT nFormat );

nFormat:

Specifies the method of formatting the text. It can be any combination of the following values (combine using the bitwise OR operator):

DT_TABSTOP: Sets tab stops. The high-order byte of nFormat is the number of characters for each tab. The default number of characters per tab is eight.

DT_EXPANDTABS: Expands tab characters. The default number of characters per tab is eight.

===========================================================================

I only guess and do it (both) & does not work ... might be you know how to do it right?

Many thanks,

Anh
