I want to create a Common File Dialog, like the one in MFC, in my ATL COM component. I turned off "MFC Support" option to minimize the COM component size.
Is there any dialog class, like CFileDialog, in ATL to do that? Or is there any easy way to do that other than create my own file dialog?
Thanks,
Tony

You can use "GetOpenFileName"/"GetSaveFileName", They are Win32API methods that can be used to open/save a file respectively. If you are just browsing for a folder, you can use "SHBrowseForFolder" API method.
Hope it helps,

Is there any easy way to resize an icon to 16x16 or a custom size through a windows function. I can think of a few ways to do this the long way ( one involving
the use stretchblt on memory DC's ).
Basically I'm using these icons with my own subclassed
buttons.
Thanks.

Try this:
<br />
hnewicon = CopyImage(holdicon, IMAGE_ICON, 16, 16, 0);<br />
where 16,16 are the new dimensions

That's not simple.
You have to draw the caption by yourself.
I don't know what to do exactly, but you have to handle many window messages, such as WM_NCPAINT, WM_NCACTIVATE and more...

I have a program that takes 3d geographic data (digital elevation model) and saves it as a 2d grayscale
bitmap where the higher elevation are represented by lighter shades and lower elevations are represented
by darker shades. I have the raw bits and put the bitmap header info on them and save as a bitmap.
I am trying to bring those raw bits into DC so that I can write text on the image before saving it as a bitmap
Any suggestions would be greatly appreciated.

Hi Paul,
create a compatible DC, select the bitmap into the dc and modify the dc.
CDC dc;
dc.CreateCompatibleDC(GetDC());
CBitmap *pOldbitmap=dc.SelectObject(pBitmap); // Your CBitmap-Object
// now modify the dc
dc.TextOut(...);
// clean up
dc.SelectObject(pOldbitmap);
Finito! Now your bitmap is modified.

Hi,
Im trying to make a dll or activex component using Visual C++ for scripting (VbSCript)
Any good articles or ideas on the topic?
What I wanna do is make a dll function in which u can pass a ado recordset and it would display it on the asp page in a table.
plz help. thanks in advance.

Hi,
There are lots of commercial products, which are doing what you need. Unfortunately I haven't seen any article of how to do that. But it's pretty simple to do... You can read the data from the recordset and then display it in the table using the Write method of the IResponse interface.
Your question is too generic and if you can ask something more specific I will be glad to help you.

Is there someone out there that can help me solve this problem? I am an intern working on an E-Mail Alert Software program. The pre-existing code was written in document form, my job is to create a user interface in dialog form. These two simply aren't compatible and I am trying to switch the former code to a dialog based application. Please, any help would be greatly appreciated.

Terry,
Maybe you are thinking it is harder than it actually is,
As long as you aren't using extensive Doc/View architecture,
It's just a lot of Copying and Pasting,
Or stick with your Form/View but in the main init/instance
Hide your main window, and open a Modal Dialog Window that points back to the parent, for your function calls etc,
Actually I always thought anything you manage to do in a dialog App you can do in a form app plus you have Doc/View and serialization etc more readily available !

Hi,
i have a big bitmap file and want to separate it into smaller bitmaps. What is the easiest way to do this?
I thought it would be a good idea to blit a small rectangle of the bitmap into another, smaller bitmap,
but i didn't find out how to do that.
Is it possible that way?
Thank you,
Chris.

Hi Chris,
You have to create a compatible DC for both source and destination bitmaps, with CreateCompatibleDC().
Then you select those bitmaps in their respective DC with SelectObject().
Then all you have to do is a BitBlt() specifying which portion of the source bitmap is to be copied.
Cheers,
Paolo.

Hello!
Can anybody help me in my trouble?
I develop application whitch provide his own page setup dialog(Word97 pagesetup dialog analog). I develop and debug it on Epson stylus photo 750 printer. For some my requests I use DeviceCapabilities function with code DC_MAXEXTENT and DC_MINEXTENT. All work fine. Then I try to work with HP LaserJet 4050. It's terrible! DeviceCapabilities return incorrect values, and GetLastError say me what "Data area passed to system call is too small", But MSDN say what i do not shell pass any buffer into DeviceCapabilities with this codes.
Please! If you may halp me, Answer to my question. I be very glad.

Hello,
in the OO-Land (where we all like to live) it's common to implement Object Models, e.g. this one:
CCompany
>CEmployees
>CEmployee
For the sake of simplicity we'll say that the company class has a member of type CTypedPtrArray (it's the CEmployees collection). Now I'd like to design my hierarchy so, that each employee has got reference (pointer) to it's parent (company).
Now my problem:
Let's say I my CCompany looks somewhat like this:
#include "employee.h" // my employee class
class CCompany{
public:
// details ommitted
CEmployee& AddEmployee(const CEmployee& newemp, CCompany* parent);
private:
CTypedPtrArray<cptrarray, cemployee*=""> m_aEmployees;
}
In this class I need to #include "employee.h". This is fine so far. Now the CEmployee class:
#include "company.h"
class CEmployee{
// details ommitted
private:
CCompany* m_ptrParent;
}
This code doesn't compile. Yes, not even if it is correctly implemented. If you include header A into header B and header B into header A, funny things happen. How do I get this working? What I'm asking for is rather a general answer on how to design such a thing rather then a void*-type-of solution.
Many thanx for your time
Matthias

Just declare a forward-reference to the classes.
e.g.
class CCompany;<br />
<br />
class CEmployee{<br />
private:<br />
CCompany* m_ptrParent;<br />
}
Then, only in the cpp file, include the "company.h"
Since in your classes, you use only references and pointers, the size of the real class is not needed for the compiler.
|

|

Uwe gave you the correct answer. This problem is solved with forward declarations when only a pointer or reference to the object is used. Since pointers and references are always 4 bytes (in Win32) then the compiler can do its thing without caring about what the pointer/reference is for.
Regards,
Alvaro

Well, a simple answer for you (I guess <g>) with a big effect for me.
Thanks for your help!

I am finding it impossible to create a popup submenu dynamically inside an existing popup menu (from a template) and then populate it with menu items. I'm trying to modify the tempalte menus inside the CMainFrame::OnInitMenuPopup() handler. I've been through all the CMenu documentation and can't figure out the trick to this. I can insert and append menu items to my heart's content, but not popups! Is there sample code somewhere for doing this sort of thing?
More details: I can successfully create a submenu entry in the popup using CMenu::InsertMenu(..., MF_POPUP, ...) but there is no right arrow in the menu. Also, when I open the popup menu a second time, the submenu entry is grayed out. So I don't seem to be able to begin the submenu successfully, nor can I populate it. I would guess that populating the submenu would also be done by OnInitMenuPopup() when it was called (*if* I could get an arrow on the submenu entry!). A big question here is then how I could know that it is my submenu being passed into OnInitMenuPopup() since there are not any commands yet defined to test against. I was thinking of saving the m_hMenu when I created the submenu and then checking against the CMenu->m_hMenu passed into OnInitMenuPopup()? But this seems a little kludgy. I'm certainly not a "beginner" and I can't figure it out from the docs I've found. Why did they make it this hard?
