For some reason I cant add member variables to items in dialogs, either via the context menu or CTRL and double clicking. If I add say a radio button to the About Dialog it works there, but CTRL + double clicking on a control in a user defined form just brings up the add class dialog.
Any help appreciated

Not possible! The modality of a window is not a window style. It's simulated via code. For example, the CDialog::DoModal will disable the parent window till the dialog is dismissed! That's how it gives us a modal feel!

I got the idea. Actually I want some trigger event in order to trap the modal dialog box creation. SO whenever the modal dialog box created the parent window style is changed to WS_DISABLED

Hello!
I'm writing an activex control and I wondered how I could return a pointer to a class object back to a JavaScript Variable. I know that sounds really weird but I'll give you an example:
Here's the java script:
--------------------------------------------------------------------------------
1: var testbox;
2: var variable = document.testcontrol; // this points to the active control <object idclass="blahblahblah" id="testcontrol">
4: testbox = variable.CreateMsgBox();
5: testbox.SetText("Hello Universe"); // im sick of "Hello World" lol <img src="images/smilies/smile.gif" border="0" alt="">
--------------------------------------------------------------------------------
Let me explain the above code. When the variable named "variable" calls the IDispatch method CreateMsgBox(), on line 4, I want it to return a pointer from the newly created class back to the variable "testbox". Then on line 5 I can access the class methods through the "testbox".
Heres the pusedo code of the c++ code when one calls the CreateBox() function above.
--------------------------------------------------------------------------------
CCreateBox CreateBox()
{
1: CCreateBox newBox; // CCreateBox is the MsgBox class
2: return newBox;
}
--------------------------------------------------------------------------------
I hope anyone can understand this, and if anyone can help I’d greatly appreciate it!!!!!!!!!!!!!
Thank You,
Caleb

Not a chance in hell. Your COM component runs in a different process, and could even run on a different machine. How is the system going to marshall a class pointer for you ? Both client and server need to know about the class, in fact, you're basically talking about another COM component.

Dim Rs1 As New ADODB.Recordset
Rs1 is a pointer to the Recordset interface of the ADODB object. I believe this is what you are asking for.

I have a CTreeCtrl and CTabCtrl that has a property sheet with a few property pages attached to it. The tree initially is selected. If you press the Tab key the focus moves the the TabCtrl. If you press Tab again the focus should go back to the tree but it doesn't. I was thinking of watching for when the Tab key is pressed then setting the focus to the tree but I'd think there is an easier way.

If you don't have any datasource it is better to use other grids like flex grid or grids in CP.

How do I code it so that when a button is press the data on the ComboBox randomize? Please help this newbie programmer.
|
|
|
|
|
Let's say the button is called IDC_BUTTON1
So i guess by now u should know how to do a event for IDC_BUTTON1? Hook on the msg BN_CLICKED.
So let's say you have assigned the combobox to a variable called m_comboBox. This can be done thru class wizard.
You would get
void ClassName::OnButton1
{
m_comboBox.AddString("....");// Your random data
}
Hope this helps.

I'm sorry, perhaps I didn't explained in detail what I want to achieved. Say my combobox have 5 data entries (properties -> data)
data1
data2
data3
data4
data5
When you press the button, it pick one of those entries and make it the display entry.

Generate a random number between 0 and CComboBox::GetCount() - 1
Now use CComboBox::GetLBText() on this random number.
Is that what you wanted? Now each time you get a random entry from the combo box

To generate random numbers, use the srand(time(NULL)) to seed the generator.
Then use rand() to get a random number between 0 and MAX_INT (4 billion or so).
To scale this massive range down to that of your listbox, use this formula:
rand() % listbox.ItemCount (or whatever the property is)
That will generate a number between zero and listbox.ItemCount - 1.
You +/- and constant value if you need to shift the lower limit or use rand() % (listbox.ItemCount + x) to shift the upper limit.

This will be my last time asking, please try to help me this last time.
rand() % listbox.ItemCount
I understand that, but say I have a combobox name IDC_COMBO1, how do I tell its name to use inside my codes?
|
|
|
|
|
To assign a value to the Combobox use the Class Wizard. The steps to do this are:
1. bring up the class wizard (menu VIEW--> ClassWizard).
2. Go to the Member Variables tab.
3. Select the IDC_COMBO1 control ID and them press the ADD VARIABLE button.
4. Give the variable a name, set category to VALUE and press OK.

I am in the process of converting several applications writting in a combination of Borland Builder 4/5 and Borland C++ to Microsoft Visual C++
Does anyone have any experience doing this and if so, have any suggestions or offers of advise on where and how to start? Web sites, tech guides, books etc. I would be most appreciative!
|

I've converted some code from Borland C++ 5.01 (not Builder) to VC++. Most was easy but had to learn STL and convert all code that used Borlands BIDs containers to STL. Also helps to know VC++'s IDE and little things like why and how to use a stdafx.h file, what includes to use for MFC stuff, the differences between the C++ runtime library versions i.e. the difference between #include <iostream.h> or #include <iostream>.
Also, I did not convert over any of the OWL code to MFC. I still have to learn MFC but it doesn't seem that hard and I've had some minor exposure to it. I suggest a complete rewrite of any of Borland's windows code to MFC.
If you have any specific problems you encounter you can send me an email and I'll try my best to answer.

Hi all, I have some quick fire questions that I would love to know the answers to, so please reply even if you only know one or two, or even have an idea.
1.) How do you go about assigning the 6 char string "Arial" to the LOGFONT.lfFontName property? I keep getting an error about can't convert from char [6] to char [32]?
2.) Is the only way of displaying text with DirectX by use of GDI's HFONT and TextOut methods having retrieved a DC from the surface the text is to go to?
3.) Is it normal to create a HFONT based on the newest LOGFONT spec using CreateFontIndirect() and delete it using DeleteObject(hFont) after the desired text has been displayed. Or is better to create multiple HFONTs for differing texts? Basically is there a time penalty for creating/deleting HFONTs?
4.) How do I get the current screen resolution? At the moment I am using the EnumDisplayModes() with my own callback function. Could I use this to find it?
5.) Is there anyway of using a reference to a structure to save me typing out the structure name when accessing its properties? so that:
MYSTRUCT hello;
hello.name = "hello";
hello.width = 1;
hello.height = 2;
-------------------
MYSTRUCT hello;
*using* hello;
name = "hello";
width = 1;
height = 2;
*end* hello;
-------------------
Thanks for getting this far, hope you can answer some of the questions. Cheers all,
Alan.

hello.name = "hello";
1. you can't do this in C/C++. hello.name isn't a CString object, it's just an array of characters. so you have to do this : strncpy(hello.name, 32, "Arial");
4. use GetDeviceCaps
5. nope, not in C/C++

Thanks for the reply Chris, your answers worked a treat. Sorry I didn't get back to sooner, but I went to bed straight after I posted the questions. I am just wondering how to pull out the system and graphics card name, clock speed, RAM etc.? I might find this information useful. I know you can get some of them through enumeration but this seems an awfully long way to go about getting information on the current spec.
Again my thanks to you Chris.
Alan.
