Setting Drop Down Heigh of a ComboBox

9-Nov-02 12:07

You can't do that directly. The compiler never sees "IDS_STRING1", only the number that it is #defined as.
You'll need to create a lookup table (using std::map for example) to convert from the string to the numerical equivalent.

I feel kind of stupid asking this question, but I couldn't find it at msdn, nor any other webpages. How can I set the drop down height of a comboboxex that is on a dialog? Thanks,

Not such a stupid question. You need to get the handle (HWND) of the dropdown list. AFAICR this is only available on one of the WM_CTLCOLORLISTOBX messages. Check the MSDN docs. Once you have the HWND resize as normal.

Note that if you create the dialog manually (ie. m_cmb.Create(...)) then the height specified is the height that will be used for the dropdown list.

HTH Smile | :)

If you're doing this from the dialog editor...

Click on the down-arrow for your combo-box. The size frame with switch modes to show the height of the drop-down.

Script error on "add event handler" in resource editor

Rewbs9-Nov-02 8:08

Hi all,

I just added a dialog box to my project in the resource editor. I also added a button to the dialog. When I right-click the button and select "add event handler", I get the following error message:

"An error has occured in the script on this page:
[...]\Vc7\VCWizards\CommandWiz\HTML\1033\default.htm
Line: 327
Char: 4
Error: Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus.
Code: 0"

I think the actual code that it is failing on is the JScript that adds the project class names into the event handler wizard.

Any thoughts on what might be causing this?

All the best,
Rewbs.

HMENU gMen = MAKEINTRESOURCE(IDR_STICKY_MENU);
cs.hMenu = gMen;

doesn't work Frown | :(

and i can't find alot in MSDN, or is this a completely bad idea?

Use LoadMenu() to load it from your resources.

What's the answer to this template question?

9-Nov-02 7:50

You have to load the menu using the LoadMenu function.

HMENU gMen = LoadMenu(hInstance, MAKEINTRESOURCE(IDR_STICKY_MENU));
cs.hMenu = gMen;

hInstance is the instance of the app-file which contains the menu resource.

NOTICE: In the following example, I had to use double angle brackets because single angle brackets were not showing up.

If I have the following piece of code, and I were to instantiate 'X' as X<<char*>>

template<<class t="">>
class X
{
...
const T m;
...
};

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

it would yield 'm' as

char *const m;

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

However, suppose I don't want to end up with 'm' as a constant pointer to a character object, but wanted 'm' to end up as a pointer to a constant object of type character. How would I instantiate 'X'?

NOTE: I DON'T want to declare 'm' as a pointer, e.g.

const T *m;

and then instantiate 'X' as X<<char>>

Thanks.

Cool | :cool:

I'm thinking you want an array:

template<class T, int n>
class X
{
// ...
const T m_Array[n];
// ...
};

Thus X<char, 32> MyInstance; would give you const char m_Array[32].

Varying CListView Row heights

Hello,

Is there a way to have CListView (report style) draw rows with varying heights (e.g., one row would have one line of text, the next would have 3, etc.)? If not, what would you suggest as the easiest way to make such a control?

Thanks!

This is possible but only if you are willing to do the drawing and measuring of the rows yourself. Check out this article[^].

getting a temporary folder without ~?

Anonymous9-Nov-02 2:58

Hi,

I'm having problems finding a good function to find a temporary folder. I've used GetTempPath() and it returned something along the lines of

C:\Docume~1/Jack/Local~1/Temp

and that's fine but I can't use it because after copying some files into this dir I also have to set a registry key regarding one of the files and it doesn't work right because of the ~ in the name. If someone could help me figure out how to do one of the following I'd appreciate it a lot, I'm getting tired of trying to find a solution to this annoying problem. It only has to work on XP.

1. A way to get the FULL path of a users temp folder without ~
-or-
2. A way to convert a path with ~ to a FULL path without ~

Thanks,
Martin

Perhaps you should have a look at the function

DWORD GetFullPathName(
  LPCTSTR lpFileName,  // pointer to name of file to find path for
  DWORD nBufferLength, // size, in characters, of path buffer
  LPTSTR lpBuffer,     // pointer to path buffer
  LPTSTR *lpFilePart   // pointer to filename in path
);

in MSDN.

Michael Dunn9-Nov-02 6:31

I would suggest that if a ~ is breaking your code, then fix whatever that bug is. Smile | :)

But you can use GetLongPathName() if you're using 98+ or 2000+.

GetLongPathName() only works on 98+.
GetFullPathName() works on 95 too.

So why not using GetFullPathName?

Because GetFullPathName() doesn't do what the original poster wanted to do. From MSDN:

GetFullPathName does no conversion of the specified file name, lpFileName. If the specified file name exists, you can use GetLongPathName and GetShortPathName to convert to long and short path names, respectively.

So MSDN itself says you have to use other functions to convert between the LFN and SFN names.
