Presuming that you're trying to get CButton type controls on a CView based window...
.... you should probably use CFormView for your view class.

I'm trying to select a row in my CListCtrl at runtime, but I just can't get it to work.
this->m_myList.SetSelectionMark(0);
int test = this->m_myList.GetSelectionMark();
It seems like the selection is successful, since 'test' always becomes 0. But the row is not being selected! What am I doing wrong here...

>>> From MSDN >>>
The selection mark is the item index from which a multiple selection starts
<<<
To select an item, you should use the SetItemState() member.
wndMyListCtrl.SetItemState ( 0, LVIS_FOCUSED | LVIS_SELECTED );
BTW: there is no need to prefix you statements with this->, it is assumed.

Read the entire file into a buffer, then write it back minus the first part.

Hi
how can I program an addin for the Internet Explorer.
I want to insert a button to the IE-toolbat to execute some code.
e.g. the download-manager "FlashGet" inserts a button to the toolbar.
how can I achieve this?
thanks

There are three types of extensions you can add to Internet Explorer: Explorer Bars (like the Search, History, and Favorites frame on the left side of an IE window), Tool Bands (Tool bars at the top of the window), and Desk Bands (A Tool Band docked to the desktop).
There is an article in MSDN that describes all of the COM interfaces and registry entries that you will need to use to implement your own.
If you have the MSDN Library on your hard drive, the folder path is: Platform SDK -> User Interface Services -> Windows Shell -> Shell Programmers Guide -> Advanced Shell Techniques -> Creating Custom Explorer Bars, Tool Bands, and Desk Bands.
For the on-line MSDN library, the URL is:
http://msdn.microsoft.com/library/en-us/shellcc/platform/Shell/Bands.asp

Hi,
Anyone can say me if the CHAR function for translate a ASCII to a Character in VC++ exist or I must to create a function that convert it.
Best regards
youssef

|

you don't need any special function, in C.
char a = 'A'; is the same thing as
char a = 65;
-c

By using GDI+ or Paintlib ( I forget the URL but it's in the FAQ )

Wow! Christian, are you saying that GDI+ actually handles the tiff format? No more third party imaging libraries!!???? I have not looked at it yet, but Maybe I should!
|
|
|
|
|
Never mind. I finally went out and looked at your stuff and anwered my own question. Thanks! I have not been doing any GDI stuff lately so I was not paying any attention to GDI+. But I've been playing around with a little personnal app for displaying and editing digital historic maps and spent nearly two hours yesterday evaluating various freeware imageing libraries. Looks like I've got a date with GDI+! Thanks.

Ive been using mfc for a while but have never really attempted to do anything more complicated with regards to UI than simple diaogs or the sdi/mdi apps i get with appwizard. Now I wanted to do some of the docking dialogs etc like in visual studio and I really havent got a clue where to start....
Can some kind person explain to me when we might derive from CView, and what exactly is CView for? And also, when I derive from CFormView, the form always has a border of about 1cm around it which looks really tacky inside the main frame. Also, in applications such as MS Messenger I think the view changes from an HTML View to a TreeView or something like that- what is the best way of doing this?
Finally, one other question how do I make my application maximised when it starts (its an mdi application) or more to the point make it open to a certain size. I have to resize my forms every time i open them-
thanks in advance

CView is for a generic view. CEditView is an edit view which is derived from CView. Its kinda like CWnd, everything pretty much breaks down to it but you generally don't use it unless you are making your own controls/windows. CFormView is basically a dialog thats why it has a frame. You can probably ditch the frame in the PreCreateWindow() function by modifying the CREATESTRUCT cs. As far as the maximized/size that would also be done in PreCreateWindow(CREATESTRUCT cs) like so...
for a specific size/posistion:
cs.cx = 250 (width of window)
cs.cy = 250 (height of window)
cs.x = 0 (x coordinate of upper left corner of window)
cs.y = 0 (y coordinate of upper left corner of window)
for maximized:
cs.style |= WS_MAXIMIZE;

I am writing a function that need to return a variant data type ,some times string sometimes integral and so on.so I declare a variale with a VARIANT data type but I chocked when I know that I must determine wich type of variant before I use it(VT_U8,VT_I and ...).
I thought it is like a Variant type in Visual Basic.
So can any body tell me how can do that.
M.S.
|
|
|
|
|
have you looked in msdn documentation for _variant_t. I am certain you will find your answer there.
|
|
|
|
|
Is Simple.
If you have a value like Integer.
you need to use some like this
_variant_t var;
var.vt = VT_I2;
var.iVal = iVal; //where iVal is your variable.
VT_I4 is for Long, etc....
For a variable type string you need to make this.
vtFld.vt = VT_BSTR;
vtFld.bstrVal = _bstr_t(strValue);
And for read variants is the same...
Good Luck!!!!!

Is there a way i can manipulate a CString in order for me to insert a linebreak manually for an edit box. I am changing data inside the editbox via CString and need to be able to line break, and the regular \n doesn't work, it just shows an unusual character.
Thanks

Try \r\n instead of \n on its own.
Cheers.

I thought I'd just done something wierd last time, because I created a new object and was able to use it right away using the code I posted before. But now I've created a new ATL project, on a different machine and the same thing is happening.
I create an ATL object, I create a method, and I compile it. I use MinDependency, making sure I specify -GX for try/catch unwinding and remove _ATL_MIN_CRT if necessary.
Then I #import the .tlb file in my stdafx of a brand new, stock standard dialog project. I call CoInitialise(NULL) before anything else in InitInstance, and in ExitInstance I call CoUninitialise().
Then in my OnInitDialog I try something like IMyClassPtr ptr(_uuidof(MyClass)); and if I do it in a try catch block I get a Message Box up with the _com_error ErrorMessage(), which is Class Not Registered ( or something similar, maybe Object Not Registered ? ).
I have tried RegSrv32 to register it myself, verified it has the proper Registry entries ( to the best of my knowledge, the name is stored under the IID with some other info ), and this despite VC++ putting up a 'registering server' type message when I compile. I've tried other methods of creating the file and my pointer is always NULL. The book I am working from seems to assume what I am doing will *always* work, because it gives no further info. Is there something glaringly obvious I am doing wrong ?
Thanks again...
Christian
