Tks for the tip. However, jus to note, this programme in VB does not include the "video streaming" codes both in the exe version and the compilable version. So its not that free afterall.
Anyway, thank you for this tip.

I created a VC++ app that calls a VB created ActiveX DLL, but its returns a failure when I execute the CoCreateInstance function for the COM handle.
|
|
|
|
|
Did you call the CoInitialize or CoInitializeEx on the beginning of your application? (every thread - including main thread of the application must have initialize the support for COM subsystem to be able to use it)
|
|
|
|
|
Yes, I did call the CoInitialize at the beginning of the app. Does the CoCreateInstance work differently in NT as opposed to Win2000 because when I run my app in NT, it seems to run through this step without an error message, but in Win2000 this step generates an error
|
|
|
|
|
normally not - what exactly the CoCreateInstance returns to you as an error - this HRESULT value?

I need to identify any and all SCSI devices attached to a system, whether it's a scanner, CDROM, hard drive, tape drive, etc.
I've been looking at:
CreateFile( "\\.\SCSIx:", ... ); // x = some int
DeviceIoControl( ..., IOCTL_SCSI_GET_INQUIRY_DATA, ... )
...however this seems to pick up all storage devices...regardless of whether the device is truly SCSI or not (ie, it'll pick up my IDE hard drives, IDE CDROM drives and even virtual IDE CDROM drives).
None of the buffers that get filled in seem to have any indicator of being a "true" SCSI device or not...
What *is* the proper way to iterate through the "real" SCSI chain from a user-mode app written in C/C++?

I'm trying to implement the compareitem and drawitem for a combobox. The compareitem is called when I call addstring, but in the drawitem i'm not getting the correct string values. Any ideas.
Thanks
|
|
|
|
|
Can you please be a bit more specific? What are the incorrect values you are getting, and what do you expect there? What is the code you are using to draw the item?

The CompareItem Function seems to work fine. I can't get the DrawItem to display the sorted data.
void CCBX::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
// TODO: Add your code to draw the specified item
ASSERT(lpDrawItemStruct->CtlType == ODT_COMBOBOX);
LPSTR lpszText = (LPSTR)lpDrawItemStruct->itemData;
CDC dc;
dc.Attach(lpDrawItemStruct->hDC);
dc.DrawText(lpszText, strlen(lpszText),
&lpDrawItemStruct->rcItem,DT_SINGLELINE);
dc.Detach();
}
Thanks

I want to set focus in the edit part of the combobox after I select an item from a listCtrl. SO I have in:
OnItemChanged()
{
GoToDlgCtrl(GetDlgItem(IDC_COMBO1)->GetDlgItem(1001));
When I have the mouse button clicked down (and not yet released back up) while I am in the listCtrl making my selection, the focus does go to the combo editpart. I see the cursor blinking there. The moment I release the mouse the focus vanishes, and the item I selected looks highlighted in blue. How do I make my focus stay in the combo? I even tried postMessaging from within the ItemChanged to setFocus but that didnt do it either....
Appreciate your help,
ns
Of course I had tried the m_combo1.SetFocus() too but no go..

I need a dialog to lock my app, at the same time I locked desktop, so no one can run another app, but F1 key can not disable successfully, when I press F1, it pass through my dialog and to CxxApp, which generate WM_HELP by default, I want to avoid it in this situation, How can I do it?
BOOL CLockDlg::PreTranslateMessage(MSG* pMsg)<br />
{<br />
if(pMsg->message==WM_KEYDOWN)<br />
{<br />
switch(pMsg->wParam)<br />
{<br />
case VK_ESCAPE: return TRUE;<br />
<br />
}<br />
} <br />
<br />
return CDialog::PreTranslateMessage(pMsg);<br />
}<br />
Thank you in advance.;)
Best Regards

I have a collection of independant UI components, that I can place in dialogs to build more complex dialogs.
When the data from one of the component is modified, I may need to update another component.
I don't want the components to know about other component; and each component has a pointer to its parent dialog.
so, I'm doing something like this :
...
void SomeDerivedComponent::SomeMethodThatChangedTheComponent()
{
m_pParentDialog->ComponentChanged(this);
}
...
void ParentDialogClass::ComponentChanged( ComponentBaseClass* pComponent)
{
if ( dynamic_cast<SomeDerivedComponent>(pComponent) != NULL )
{
}
}
When I update the components in the parent dialog , I only pull info from the components, I don't want to have the components send/push back info to the parent either.
Does it sound ok ?
Thanks.

It sounds okay.
As a reference, Windows controls tend to use a mixture of the approaches. When they change, or an event occurs, they send a message to their parent (meaning that the parent does not have to implement a certain interface, but may optionally handle the notification messages, normally sent as WM_COMMAND or WM_NOTIFY). Some controls just send a message saying that something changed, like a combo box sends a message saying the selection changed, without providing any information about what the selection has changed to - you need to query it. Other controls, such as a tree control, send much more information in their notify messages, often providing all the information required (such as the previously selected item, the new item, the item state etc.).
The only change i would suggest is to change the controls from using a pointer to the parent and calling a function, to sending a custom message to the parent. This will make the controls easier to reuse in another situation, because they won't be hardcoded to use a specific parent dialog.

I wanted to do this, but I kinda' don't like Windows that much; and the derived components, are only used in those instances.
But I will try it, since it's not a big change to what I've already done, only replace the pointer by a SendMessage(...);
I also thought of using a observer pattern but that meant too much work ...
Thanks

Hi,
In adialog based application, i have a listbox for showing some
info data. Now i want to know how to add "PageUp" and "PageDown"
functions in the listbox? How to do this? Is there any reference about this?
Thanks in advance!

Try sending a WM_VSCROLL message to the list box (see MSDN for details on what WPARAM and LPARAM are - i can't remember off the top of my head).

I have a bit of a problem. We have a lot of legacy apps that ares spread across three different platforms - desktop Windows, CE 2.12 devices WITHOUT MFC/user interface stuff, and now, PocketPC 2002 with MFC and user interface stuff. They all use STL for strings and collection stuff.
What I want is a set of collection classes that does NOT use MFC or STL, but that provide the same functionality. The optimum solution would be the MFC collection classes extracted from and with no reliance on the rest of the MFC library.
Barring that, I need an STL library which supports Windows, CE 2.12, CE 3.0, and PocketPC 2002.
I already have a replacement for the MFC CString class that doesn't use STL, but I still need a set of collection classes.
Any info, help, scolding, insulting?

Does STLPort[^] work with these platforms?
It compiles almost everywhere you can start a c++ compiler.

I downloaded STLPort (I hate STL).

I hate STL even more now.
STLPort is NOTHING like the SGI implementation...
So much for portability, eh?
