Hi,

I want to invoke a html page from my EVC++ program and so have tried the following line of code:
CreateProcess (TEXT("iexplore.exe"), TEXT("\SIMPLEBUTTON.HTML"), NULL,
NULL, FALSE, 0, NULL, NULL, NULL, NULL);

The program launches the internet explorer but doesnot open the page, though the path given is right. If anybody can throw any light on this, I would be grateful.

Thankyou,
Deepa

signature control with TIFF files

Hi all -
The current signature tool I am using on Pocket PC device is easyink which deals only with bmp files. Is there any similar tool which displays and saves signature in TIFF format.
Right now we have a bmp to TIFF convertor routine. But we'll have to write TIFF to bmp convertor again in order to display the signature on the device via easyink.
Any ideas? anybody has a clue about bmp to TIFF convertor routine or a tool like that?
Any other efficient idea to store the signatures? Please let me know

Thanks & Regards,

CAN NOT DEPLOY/DEBUG a CF application in any language ON THE IPAQ EMULATOR after installing the FULL REMOTE DEBUGGING COMPONENTS.

the ipac emulator 2002 was working fine until then. I reloaded the entire .NET system including the framework, vs .net and it still does not work.

does anybody have any idea where in the registry is the debugging information kept?

I really don't want to rebuild the entire system if I don't have to...

versions used:
Microsoft development environment version 7.1.3088
Microsoft .NET Framework 1.1 version 1.1.4322

Any help will be greatly appreciated….

thanks

Registering DLLs

I have developed a plugin dll for Autodesk OnSite View using eMbedded Visual C++ 3.0 and it works just fine with the older models. But the compiler is unable to register the DLL automatically on compiling with the newer model Pocket PCs.

I was wondering if it is possible for me to register this DLL manually? Or if there was some other solution to the this problem. Thanks.

if the dll can be registered in the Pocket PC , you can use the following app to do this :

I use it in a hx4700 IPAQ and I can register dll manually.

I would like to start writing apps for my pocket pc running windows ce. I've just downloaded eMbedded Visual C++ 3.0 and I don't have a handle on it just yet. Can anyone direct me to a tutorial or a site for learning eMbedded?

Also, I've tried to enter some of my code into eMbedded (which compiles in .net) and it didn't work. Then I tried something simple. Why doesn't this code work in eMbedded:

#include <iostream>
using namespace std;

int main()
{
cout<<"Hello World";
return 0;
}

Thanks!

Sending a BN_CLICKED message

Hi, I need to send a button click message to a dialog window button from a thread. I use "PostMessage(BN_CLICKED, IDC_GPS,m_hWnd) " but I think the lparam and wparam are incorrect. I don't find an example or something else.

Can anybody help me?

Thank you.

I try to use use PostMessage(WM_COMMAND, MAKEWPARAM(IDC_GPS, BN_CLICKED), <button
> handle>).

Then I try to use "HWND GetDlgItem( int nID )" to get the button handle, but the
compiler makes a error: I can use Cwnd::GetDlgItem ( ) , but not
CWindow::GetDlgItem , which returns the button handle.

How can I use the Window classe?
Thanks.

Javier

The BN_CLICKED message is a notification sent to the button's parent window. If you want to simulate a button press, send the BM_CLICK message to the button.

Hi, João .

ok, I use:

HWND Hbutton = GetDlgItem(ptrDlg->m_hWnd,IDOK);<br />
SendMessage (Hbutton,BM_CLICK,0,0);

from my thread and it works.

Another question: if I want to send it from the same dialog window (for example from other button), How can I get the handle to the button? Well, I test the following:

SendDlgItemMessage(IDC_GPS,BM_CLICK, 0, 0 );

from the same dialog and it works.

Thanks

Hi,
What is the difference between Win CE 4.2 and Windows Mobile 2003?
Does Embedded visual c++ 4 support development for Windows Mobile 2003 as it does for WinCE 4.2?

O.K
I realized that Windows Mobile 2003 is actually Windows CE .NET 4.2.
There is a good article :

ReleaseDC doesn't release memory

~k10-Dec-04 0:43

10-Dec-04 0:43

I had problems using GetDC and ReleaseDC, so I built a blank MFC app like this:

BOOL CTestdcDlg::OnInitDialog()<br />
{<br />
CDialog::OnInitDialog();<br />
<br />
// Set the icon for this dialog. The framework does this automatically<br />
// when the application's main window is not a dialog<br />
SetIcon(m_hIcon, TRUE); // Set big icon<br />
SetIcon(m_hIcon, FALSE); // Set small icon<br />
<br />
CenterWindow(GetDesktopWindow()); // center to the hpc screen<br />
<br />
// TODO: Add extra initialization here<br />
SetTimer(1,200,NULL); <br />
return TRUE; // return TRUE unless you set the focus to a control<br />
}<br />
<br />
<br />
<br />
void CTestdcDlg::OnTimer(UINT nIDEvent) <br />
{<br />
// TODO: Add your message handler code here and/or call default<br />
CDC *myDC;<br />
switch(nIDEvent)<br />
{<br />
case 1:<br />
myDC=GetDC();<br />
ReleaseDC(myDC);<br />
break;<br />
}<br />
CDialog::OnTimer(nIDEvent);<br />
}

The memory used by this application increases continuously.
What am I missing?
This issue is causing me a lot of problems, do you ever encountered a problem like this?

Thanks,

Keraam

Hi,
I don't really see the problem,but try to change the timer interval(i don't think that GetDC() and ReleaseDC() takes more than 200msec,but maybe it's the problem).

Good luck
Eli

I fixed the problem using handles instead of pointers for the dc, but I really don't understand why it happens.

Pointer to severals Dialogs

Hi, I need to have a pointer to a dialog window from a thread. I made a global pointer variable to a dialog window and it works. But Is it possible to do a pointer which can pointer to several dialogs (one at the same time)?

I need to pointer to the active dialog from the thread(the active dialog window it's not the same all the time). I try "void* pointer" but doesn't work, (there'is a error in the reference to the pointer inside the thread).

Regards.

You must access the pointer value inside a critical section. Otherwise you risk having data corruption.

CE remote display / VNC?

Hi everybody,

I am developing a collaboration application on a Win CE .NET 4.2 based device and Windows 2k/XP based devices and I am trying to remote control the CE device (e.g. like it is possible on desktops with VNC). Basically, this is possible, since it can be done with the Active Sync remote display application. However I'd like to create my own remote control and integrate it into my appliaction, hence my question is: Is it possible to use the interface the AS remote display uses? Does anybody know if this protocol/API is documented somewhere?

Thank you very much Smile | :)

How to convert BD_ADDR to BT_ADDR?

Hi,
In order to create a virtual COM port(for BlueTooth Comunication),
I need the address of the BlueTooth device.
I know the BD_ADDR,but i must convert it to BT_ADDR if i want to use
the RegisterDevice() function.

anyone?

Regards,
Eli

First, you must know the bluetooth stack that your device has. RegisterDevice() is only supported by Microsoft Bluetooth stack. For example IPAQs uses Windcomm Stack and "RegisterDevice()" doesn't work. So if it's not microsoft Stack, you must buy the correct bluetooth Stack SDK for development.

I made a virtual serial port without "RegisterDevice()" in my IPAQ. Simply uses the normal Open port, close port , read port and write port like it'was a normal serial port. I use the COM8 in my IPAQ hx4700 and it's works. When I open the port, appears a Window Dialog (made by the own Operative System) for choose the bluetooh device to connect. If you want to do this in your own app you must use a bluetooth Stack SDK for development in your device.

Regards.

Javier

Hi Javier,
First,I really appriciate your detailed answer.
just today i saw that iPaq uses the widcom stack and not the MS stack(is that the reason i can't use WSALookupServiceBrgin() etc.)?
anyway,are you using COM8 for both incoming and outgoing massages(i use also the ipaq h2210 and it use COM5 for input and COM8 for output)

Best regards,and thanx,again
