I draged and droped an added registered activex control FPCapX on simple dialog in dialog based application used to display image from hardware attached.
When I start using any of its method which interact with hardware ,it gives this assert in debug mode,and in release mode it simply does not work.Control works very simply in VB applications. Actually each of this methods internally calls InvokeHelper function where the assert comes. When I searched on google about bug I found that
Activex Control is not initialised. Can anyone help on this please.

In google search only one relevant article comes Actually in that article one is trying to set values to activex control before its dialog gets initialised. but I am trying to use capture mwthod of activex far after dialog is loaded and when user clicks button capture. One more point i want to tell you, if instead of drag and drop from control toolbar if I create control using create function of it,it doesnot give assertion but it simply does nothing

I posted a question to support at Bioenable about this - I hope they come back with an answer Smile | :)

'g'

this is the reply I received from Bioenabletech .. I suggest if you are a bona fide user of their software you take the issue up with them (they seem more interested in sales than support)

>>>
Dear Mr. Garth,
This is with reference to your requirement, The same can be achieve with our
enBSP SDK. The OCX control details will offer you a complete details about
the use and integration. In addition to that, BioEnable support Engg will
help you to integrating the same with our OCX control.

I'm trying to write a client for a Windows CE 4.2 .NET device to use Bluetooth.

I'm getting a WSAEFAULT error (10014) on bind, does anyone know why this is?
The official documentation claims that its a bad pointer or too small of size. The conversion to SOCKADDR* (16bytes) is for winsock backwards compatablity, and the type SOCKADDR_BTH is 32bytes, thus the need for the the addr length in the third parameter.

WinMain
//
UINT Bluetooth_Message = RegisterWindowMessage(TEXT("BT_MSG"));
SendMessage(HWND_BROADCAST, Bluetooth_Message, 1, 0);
Sleep(1000);

printf("Bluetooth On\n");

WORD wVersionRequested = 0x202;
WSADATA m_data;
if (0 == ::WSAStartup(wVersionRequested, &m_data))
{
SOCKET s = socket(AF_BTH, SOCK_STREAM, BTHPROTO_RFCOMM);

DWORD lastError = ::GetLastError();

if (s == INVALID_SOCKET)
{
printf("Failed to get bluetooth socket! %s\n", GetLastErrorMessage(lastError));
exit(1);
}
printf(" socket Call completed: [0x%x] with ws: %d:%d\n", s, HIBYTE(m_data.wVersion), LOBYTE(m_data.wVersion));

SOCKADDR_BTH address= { 0 };
ZeroMemory(&address,sizeof(SOCKADDR_BTH));
address.addressFamily= AF_BTH;
address.btAddr= 0x0;
address.port= BT_PORT_ANY;
// address.serviceClassId= 0l;

SOCKADDR * pAddr=(SOCKADDR*)&address;
int nAddressSize= sizeof(SOCKADDR_BTH);

if (SOCKET_ERROR == bind(s, (const sockaddr*) &address, nAddressSize))
{
printf("Error with bind:\r\nWSAERROR: %d\n", WSAGetLastError());
printf("Sizes: SKB > %d", sizeof(SOCKADDR_BTH));
printf(" %d <adr ",="" sizeof(address));
="" printf("="" ska="" %d",="" sizeof(sockaddr));

sleep(3000);

I can't seem to see anything wrong except it looks to me like the size of a SOCKADDR_BTH should
be 30, not 32.

//From ws2bth.h...
...
#include <pshpack1.h>
...
typedef struct _SOCKADDR_BTH
{
    USHORT      addressFamily;  // 2 bytes
    BTH_ADDR    btAddr;         // 8 bytes
    GUID        serviceClassId; // 16 bytes
    ULONG       port;           // 4 bytes
} SOCKADDR_BTH, *PSOCKADDR_BTH;

Am I calculating that length wrong? Smile | :)

Yep, structs are aligned 4bytes .... But I have tried using thirty in the length argument and it didn't make a difference. Although I can go up to sizeof(SOCKADDR_BTH)+8 that and after I'll get a Winsock error 10049.

What? That's not the case at all, unless you specify it somewhere.

Maybe you are using a different SDK, but the ws2bth.h from PSDK 2003 R2 sets the structure
packing in the entire header to 1, which is why I included that line in my response.

sizeof(SOCKADDR_BTH) returns 30 on my system.

I am Curious why it's 32 on your build. What header files do you use and from where?

Of course, this still doesn't explain why substituting 30 doesn't work. Smile | :)

I'm using the CeGCC compiler for Linux to create PPC executables, along with it I'm using an older sdk, probably from eVC 4. Right now I have no idea why this isn't working.I've looked through many examples and I'm doing everything correct socket initialization etc and I'm still running up on this problem. The code compiles but this crashes on runtime.

You are calculating that correctly (2 8 16 4)....could this be a platform issue with allignment? Size of SOCKADDR_BTH is returning 32.
Could you test sizeof(SOCKADDR_BTH) on your machine?

That's what I was wondering originally. Using Platform SDK for Windows Server 2003 R2 header
files, sizeof(SOCKADDR_BTH) returns 30.

I was thinking it may be different building for CE but I can't find anything that indicates that
it should be.

I've used SetWindowsHookEx() and placed the hook procedure in a DLL, as it is a global hook.. I was just wondering how I call the CallNextHookEx() API from the hook procedure in the DLL because the first parameter is the hook handle, which I don't have access to, as SetWindowsHookEx() is called from the actual executable. Is there a way of obtaining this hook handle, or sharing the handle with the DLL from the executable code?

I'm working in C/C++ so no MFC

Thanks for your help!

Using Share data section.

What we usually do is that we write a function in the dll( eg - InstallHook )and from that function, the SetWindowsHookEx() is called. So the application that install hook normally call the InstallHook() function. The handle returned by the SetWindowsHookEx() is kept in a shared data segment in the dll itself.

Hello,

what is a string table ? Why all the strings added in the program not seen in the string table.
What should be seen the string table

Prithaa

The strings that you added to the string table will be visible there. It's not a case of the IDE building a table of all strings, but of you building a list of strings to store and reference from there. This gives you a central location for, for example, changing hte language of your application.

From MSDN:

It's a Windows resource that contains a list of IDs, values, and captions for all the strings of your application. String tables make it easy to localize your application into different languages. If all strings are in a string table, you can localize the application by translating the strings (and other resources) without changing source code.

Don't confuse the string table resource with string literals.

Hello,

I made some chnages in the my program and because of which I am not able to view the string table in my resourse file.
And when I go to Resource file ,it says Load failed.

How do I get my resource files back?

When the loading fails, it usually pops up a dialog asking you whether to edit resource manually. It will guide you to the location of thr .rc file where the problem occurred. In many cases, you can fix the .rc file manually. Then reload the resource again.

Best,
Jun

Close your project and visual studio. Goto the folder where your projects ".sln" file is present. Double click it. It will open and load the resource file also. (Not 100% sure abt your system). But tell me if it is working in your system.

Hello,

My project folder doesnot have .sln file. Now what should I do.

Now if I want to insert a dialog I am not able to do it.
When I click on .rc file I get a pain text file which has code written in it within BEGIN END
