I have added a menu item to the shellcontext menu using shell extensions(ATLCOM AppWizard).When i select the item some operation will be performed.Now i want to attach this feature to an SDI application i.e,when the SDI application is runned this menu item should be inserted to the shell context menu automatically .Any article based on the above problem will be of more help.So,how can i add these two applications into a single application.
Thanks.

Hi.
I need to pass parameters to sub fuction. it is surely easy. but,
when it comes to variable parameter.. how can I do that?
for example,
void MyPrintf(char * msg, ...)
{
printf(msg ,????); // <- here
// something extra
}
thanks in advance.

void MyPrintf(char * msg, ...)
{
va_list va;
va_start(msg, va);
vprintf(msg, va);

Dear all
I use AfxBeginThread in one dll program. this thread is responsible for logging data.
When I debug program, I trace until I reach the AfxBeginThread Line .
program dont continue and a suspend state begins.
When I debug the program into AfxBeginThread line, I find that When it reachs the
VERIFY(::WaitForSingleObject(startup.hEvent, INFINITE) == WAIT_OBJECT_0);
::CloseHandle(startup.hEvent);
in threadcore.cpp function, the ack of waitforsingleobject never comes and program suspends.
Do you have any idea about this problem.
Best regards
Mahdi

how are you creating the thread ?
|
|
|
|

I find the reason.
When I call the AfxBeginThread in MFC driven class constructores I see this problem.
but when I call it in another function, I dont see this problem.

Hi all
i have developed a web server. Whenever a client connect to my web server, i create a thread and process the rquest. In my thread, each time i create one COM component(Script engine vbscript.dll)using CoCreateInstance. so i am facing a problem while calling the CoCreateInstance().
Is any good method to avoid frequent calls to the COM component. I mean
one time initializing my engine and using it whenever i need
thanks

why not use this way
CoGetClassObject(rclsid, dwClsContext, NULL, IID_IClassFactory, &pCF);
hresult = pCF->CreateInstance(pUnkOuter, riid, ppvObj)
pCF->Release();
just to call
CoGetClassObject(rclsid, dwClsContext, NULL, IID_IClassFactory, &pCF);
first time it will ensure the dll loading.
then whenever you want to create an instance just call
hresult = pCF->CreateInstance(pUnkOuter, riid, ppvObj)

OK. i will change my code and let me see

Hi, i've created a droplist combo box, and listed a few item. Are there anyone who know how to link the clicked item to a certain file saved in text format. I'll then need to send the file to hardware after clicking on the ok button in the dialog box. This is some code that i found in this site. It just shows to get the selection from the droplist. In my dialog box i've created a function to open,browse and load the file. Now i need to figure out how to write the code to automatically link the clicked item in the droplist to a certain text file and also display it in the other function(open,browse and load the file). Also, each item listed in the droplist correspond to different text file. Is there any suggestion on what codes i should add? Is there any article or example that i can refer to? i'm a begineer here.
void CComboBoxTutorialDlg::OnDropListSelchange()
{
UpdateData();
if( m_nDropListIndex < 0 ) return;
CString str;
m_DropList.GetLBText( m_nDropListIndex, str );
CString Out;
Out.Format( "Drop List Selection => index %d\n%s", m_nDropListIndex, str );
AfxMessageBox( Out );
}
thanks in advance

it is better to divide your problem in parts.
1:get selection from combo box
for this you should handle the notification ON_CBN_SELCHANGE
in this handler get the selection with GetLBText()
2: how to relate data
For this purpose you can use GetItemData() and SetItemData()
or GetItemDataPtr() and SetItemDataPtr()

cyn8 wrote: UpdateData();
if( m_nDropListIndex < 0 ) return;
What is this supposed to do?
Try:
int nIndex = m_DropList.GetCurSel();
m_DropList.GetLBText(nIndex, str);

In MFC we can choose SDI, MDI or Dialog based application to create but in Win API I don't know how to create SDI application like NodePad. Please answers to me soon.
Thanks.

In Win32 API we usualy use the CreateWindow() function and WinProc() function to process messages

which represents the message), a WPARAM
(a special unsigned integer that contains extra
information about the message being sent) and finally
a LPARAM (a special long which also contains information
about the messge being sent) */

Hi,
I'm looking for a way to change the internet settings programaticly so i used many WIN32 APIs such as WININET and RAS ,I found that the second method work easily by filling the RASDIALPARAMS
structure but with only phone line connection (means that we can not use adsl modem) whereas
the first method appears difficult or its not clear for me .
Could someone give me an exemple to change all settings connection (time out, Number of retries..ext) with WININET APIs or another method if exist
Thanks
