yup, I think so (but i have no compiler for the moment, so I'll give you feedback tomorrow when I test it at home.
By the way, why does intellisense tell me SHParseDisplayName() wants a LPWSTR then ?

I cannot explain this. In my case it tells me that the first parameter is of PCWSTR type.

Because that is the way the function is defined.

did you read the other posts of the thread ?
boths ways are how the function is defined ! the problem is one is the doc online, and the other is what i'm using in my code.

My point is as far as the compiler knows, at the point of the call there is only 1 definition.
Are you sure you didn't see LPCWSTR with intellisense? Same thing as PCWSTR.
I can't find any old reference (in header files) to SHParseDisplayName() taking anything but
a const WCHAR * as the first argument. The L part of the macro is a holdover from Win16 days.

hello Viorel,
then i tried your sample, and it does compile.
but the behavior is not the one expected. 
actually, it does open the "browse for folder" dialogBox, but the folder in m_strFolder is drawn as the root folder.
what i wanted to have is still have the desktop folder as the root (exactly as if pidl was set to NULL), but with m_strFolder folder selected (the tree expanded to that folder).
another weird thing is that SHParseDisplayName() is available only since WindowsXP. wasn't it possible to have such a behavior on Windows 2000 ?! 
thanks for your contribution...  see you

Hello Comunity,
i use this funktion to show items in an CListCtrl with diferent colors, and i need to know
which item number is to be drawn.
I try to cast pNMHDR to
LPNMLVCUSTOMDRAW pLVCD = (LPNMLVCUSTOMDRAW)pNMHDR;
but i need to know the itemnumber who is to drawn...
any one have some sugestions for me?
thaks
break;

If no other solution, I think you can store the item number as a private data:
lvItem.mask = ... | LVIF_PARAM;
. . .
lvItem.lParam = (LPARAM)i;
pMatrixListResults->InsertItem(&lvItem);
Later obtain this number from the NMCUSTOMDRAW structure:
LPNMLVCUSTOMDRAW pLVCD = (LPNMLVCUSTOMDRAW)pNMHDR;
int number = (int)pLVCD->nmcd.lItemlParam;
I hope this works.

Hello,
yes, your idea works perfect, this is what i use now!
Thank you!

Why don't you use OnDrawItem?

Hello Capallini,
i never use this method, maybe i should try this.. 
regards
break;
|
|
|
|

LPNMLVCUSTOMDRAW pLVCD = (LPNMLVCUSTOMDRAW)pNMHDR;
int nItem = (int) pLVCD->nmcd.dwItemSpec;

ups,
yes, you right, i use this before in my previous project, thanks... :->

I want the elements from 1-12 enabled , and the rest(13-30) disabled

I doubt if this is possible. I don't think you could disable specific items in a CComboBox.

you have to subclass the CComboBox for same.. subclassing is the key to this type of effect

Hi all,
I have an application written in Visual C++6.0 which uses a Rich Edit Control to display user chat. I want to implement text highlighting as in MS Word for this rich edit control so that I can highlight messages from particular players.
I am using CHARFORMAT structure for formatting text. Can someone help me implementing this?
I tried using CHARFORMAT2 which has text BackColor property but it didnt help.
Thanking in anticipation

CHARFORMAT2 cf;
memset(&cf, 0, sizeof(CHARFORMAT2));
cf.cbSize = sizeof(CHARFORMAT2);
cf.dwMask = CFM_BOLD;
cf.dwEffects = CFE_BOLD;
COLORREF clr =RGB(255, 10, 15) ;
cf.dwMask =CFM_COLOR;
//cf.dwEffects = CFE_AUTOCOLOR; // Bold
cf.crTextColor = clr;

Hello All,
I have small and simple COM program to access a Add function in Dll and I am accessing this function from main program. For the simple add function it is working, interface and dll files are working properly.
For this interface I am trying to add one more function by name getdate() which of return Char* .. can any one please help how to declare the getdate() function in interface ???
Below are declaration and files with there names ….
// File interface.h
// This file contains interface related declarations.
#ifndef _A_INTERFACE_H_
#define _A_INTERFACE_H_
DECLARE_INTERFACE_(IMyA,IUnknown)
{
STDMETHOD_(LONG,MyAdd)(INT,INT) PURE;
};

From the macros you're using I guess you implement the server using ATL.
Use the class wizard to add your new interface method: right click on the interface in the class view and select "Add method..." or something like that.
Hope this helps

Hi Roger,
Thanks a lot for the response.
I was waiting for a long time for the response thanks a lot.
Actually I did not use wizard for creating interface or for adding interface methods.
I manually written the code for the Add function and its working I can access the add
Function from the main function
Main function
int main (void)
{
IClassFactory *pclsf;
IUnknown *pUnk;
IMyA *pA;
int x,y;
long result;
//Initialize the OLE libraries
CoInitialize(NULL);
//get the IClassFactory interface pointer
HRESULT hr = CoGetClassObject(
MYA_CLSID,CLSCTX_INPROC,NULL,IID_IClassFactory,
(void **) &pclsf);
//USe IMyA interface for additions
printf("Input two numbers you want to add.\n");
scanf("%d\n%d",&x,&y);
result=pA->MyAdd(x,y);
The above function is working properly now I want to add one more function to interface
Which I have mentioned in the earlier post.
Can u please help me with that .. can u please tell me how to add function to interface
// file Interface.h
DECLARE_INTERFACE_(IMyA,IUnknown)
{
STDMETHOD_(LONG,MyAdd)(INT,INT) PURE;
}
no I want to add this function
har* CMyA::getDate()
{
struct tm *newtime;
char am_pm[] = "AM";

How to add this function to interface ?? please help me out …

As I see it there are two ways of implementing a COM server using ATL:
either you use the wizard provided help or you don't.
If you choose not to use the wizards, things get a little more hard but could be worth the trouble since you'll learn a lot from it.
In my opinion the best way to learn it is by actually doing it... i.e. in your situation create a dummy ATL project and make a backup of the files, then use the wizard to add an interface method and compare the files with the files in your backup copy.
Then you'll know what to do.

Hi Roger,
I am very much new to COM , I got an example in book I just went through it and created a working dll file .
There they have not used wizard for adding methods. I know how to add a new class for the project.
Can u please tell me how to add methods to interface using Wizards. ??
Thanking you..

Have a look at this article[^] in the CodeProject COM section. It describes how to create the project and add functionality to the server.
Have a look at other articles in the same section as well, CodeProject articles are a great starting point since people often tend to write about their own experiences. Try to find an article that meets your level of expertise/knowledge on the subject and startfrom there.
The article I suggested above looks suitable given how I interpreted your needs, but there might be another article that may help you better. Simply browse through the list of COM articles and judge from the heading to sort those out that you're interested in.
