Then you need to do some research into the different parts of the project: database, transactions, UI etc. There is no simple answer that can be posted in a forum such as this.

You haven't asked for help, you asked for a full solution.
If you want help, then you first need to do as much as possible by yourself, up to the point where you don't know how to proceed. Then tell us why you can't proceed and what, precisely, it is that you don't understand or don't know how to solve.
There's no point for us to provide a full fledged answer if we don't know what you already know - we might just be wasting our time telling you what you already know!
You may be unsure on how to start, maybe you believe if your design isn't perfect right from the start then you will ultimately fail. But that is not how software development works: software development never starts with a perfect design! Instead you start with what you think works best, and go on until you realize that you can't go on, or some detalis of your design are impractical. Then, based on what you've just learned, you correct your design. If all else fails, start new from scratch.
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)

Hi, it's for MT4 plattform?
|
|
|
|
|
Is there any way to insert some icons to an CTreeCtrl, but only on some icons, and other one's not ? If yes, how can I do that ?
|
|
|
|
|
you set the icon group via CTreeCtrl::SetImageList[^], and then use the offset into the list to set the icon for individual tree items. If you use an invalid offset then no icon will be displayed.
|
|
|
|
|
Yes, I try that, but remain there an ugly empty space (between tree line and tree text) ...
|
|
|
|
|
That's the space for the icon, nothing you can do about it. You could use an image that just contains a line so it extends to the actual tree item.

Hi
To say i am very noob to windows programming world.
We are trying to develop windows application + device driver with CEN XFS compliance.
http://en.wikipedia.org/wiki/CEN/XFS
simple architectural flow:
Windows Application
|
_____________________
| XFS APIs |
(CEN/XFS SDK DLL)
| |
| XFS SPIs |
|_____________________|---XFS Manager
|
|
Service providers (SP)
(DEVICE DRIVER)
To understand the SP's functionality, we recently took one of the device vendors SP's DLL for accessing their device and we were able to successfully communicate with their device using our windows application(Eclipse MINGW based).
Then we started to check for some sample SP source in internet to try our implementation. (https://drive.google.com/file/d/0B60pejPe6yiSejRGQ3JnLUl4dzA/view)
With the linked source we were able to compile and create an output DLL. But , when we tried to access the SP, I always return error.
With windows sample application, we just tried to open the device with call (WFSOPEN) which always returned (-15 WFS_ERR_INTERNAL_ERROR ) or (-29 WFS_ERR_INVALID_SERVPROV)
Trial FLow 1 :
Application Call to manager:
hResult = WFSOpen( "QuantumT", hApp,lpszAppID, dwTraceLevel,dwTimeOut,VER_SPI_REQUIRE,&SrvcVersion,&SPIVersion,&hService);
manager translates WFSOPEN call to SP's WFPOPEN call:
HRESULT WINAPI WFPOpen(HSERVICE hService, LPSTR lpszLogicalName, HAPP hApp, LPSTR lpszAppID, DWORD dwTraceLevel, DWORD dwTimeOut, HWND hWnd, REQUESTID ReqID, HPROVIDER hProvider, DWORD dwSPIVersionsRequired, LPWFSVERSION lpSPIVersion, DWORD dwSrvcVersionsRequired, LPWFSVERSION lpSrvcVersion)
With above call flow I get (-29 WFS_ERR_INVALID_SERVPROV) as an error for my application
Trial FLow 2 (Just removed WINAPI interface for WFPOPEN in SP):
Application Call to manager:
hResult = WFSOpen("QuantumT",hApp,lpszAppID,dwTraceLevel,dwTimeOut,VER_SPI_REQUIRE,&SrvcVersion,&SPIVersion,&hService);
manager translates WFSOPEN call to SP's WFPOPEN call
HRESULT WFPOpen(HSERVICE hService, LPSTR lpszLogicalName, HAPP hApp, LPSTR lpszAppID, DWORD dwTraceLevel, DWORD dwTimeOut, HWND hWnd,REQUESTID ReqID, HPROVIDER hProvider, DWORD dwSPIVersionsRequired, LPWFSVERSION lpSPIVersion, DWORD dwSrvcVersionsRequired, LPWFSVERSION lpSrvcVersion)
With above call flow I get (-15 WFS_ERR_INTERNAL_ERROR ) as an error for my application from manger even though i force SUCCESS as return from SP to manager
I am confused why MANAGER returns different error codes to application if WINAPI definition is removed from WFPOPEN.

Request some pointers on understanding this issue.

I googled the error message you mention and could not find it in the Windows API. It doesn't look like a Windows error message. I'm afraid the maker of the device might be the only one who could help you with this problem.
EDIT:
Perhaps this is a call stack corruption caused by removing the WINAPI definition. WINAPI simply means __stdcall which is the calling convention used by the Windows API.

So, you suspect this might the issue with SP code which i am currently working with??.
|
|
|
|
|
Well, since that is not a Windows error message, I can only assume it is specific to the library you are using.

Also i see some difference in Sp's DLL which i created and actual working vendors DLL
Difference noted using PE studio's exported sysmbols option

What is the difference.Does export method differ??
|
|
|
|
|
You've hit the nail on the head! The ones on the bottom are exported like so:
extern "C"
{
}
The ones on the top are exported in C++ fashion, with name mangling.
Try exporting your functions as extern "C" .

Thanks your tip help me to start some invetigation.All these days we were with LINUX. Migrating to windows seems little difficult for me.
Where should :
extern "C"
{
}<pre></pre>
be added??
Because SPITesh.H, the code has the expected tag...
#ifdef __cplusplus
extern "C" {
#endif
SPITEST_API HRESULT WINAPI WFPCancelAsyncRequest(HSERVICE hService, REQUESTID RequestID);
SPITEST_API HRESULT WINAPI WFPClose(HSERVICE hService, HWND hWnd, REQUESTID ReqID);
SPITEST_API HRESULT WINAPI WFPDeregister(HSERVICE hService, DWORD dwEventClass, HWND hWndReg, HWND hWnd, REQUESTID ReqID);
SPITEST_API HRESULT WINAPI WFPExecute(HSERVICE hService, DWORD dwCommand, LPVOID lpCmdData, DWORD dwTimeOut, HWND hWnd, REQUESTID ReqID);
SPITEST_API HRESULT WINAPI WFPGetInfo(HSERVICE hService, DWORD dwCategory, LPVOID lpQueryDetails, DWORD dwTimeOut, HWND hWnd, REQUESTID ReqID);
SPITEST_API HRESULT WINAPI WFPLock(HSERVICE hService, DWORD dwTimeOut, HWND hWnd, REQUESTID ReqID);
SPITEST_API HRESULT WINAPI WFPOpen(HSERVICE hService, LPSTR lpszLogicalName, HAPP hApp, LPSTR lpszAppID, DWORD dwTraceLevel, DWORD dwTimeOut, HWND hWnd, REQUESTID ReqID, HPROVIDER hProvider, DWORD dwSPIVersionsRequired, LPWFSVERSION lpSPIVersion, DWORD dwSrvcVersionsRequired, LPWFSVERSION lpSrvcVersion);
SPITEST_API HRESULT WINAPI WFPRegister(HSERVICE hService, DWORD dwEventClass, HWND hWndReg, HWND hWnd, REQUESTID ReqID);
SPITEST_API HRESULT WINAPI WFPSetTraceLevel(HSERVICE hService, DWORD dwTraceLevel);
SPITEST_API HRESULT WINAPI WFPUnloadService();
SPITEST_API HRESULT WINAPI WFPUnlock(HSERVICE hService, HWND hWnd, REQUESTID ReqID);
#ifdef __cplusplus
};
#endif

What you show inside SPITesh.H is the correct placement. Is that your file or the original vendor's file?
In Visual Studio, when you compile the code as C++, it should automatically define __cplusplus .
If it doesn't, then it might be that your source file extension is ".c" when it should be ".cpp".

Yes, I sm trying to follow the same. but still it is doing no good.
https://drive.google.com/file/d/0B60pejPe6yiSejRGQ3JnLUl4dzA/view[^]
The link contains the project ref files i made sure all files are CPP and Extern C just for the headers.
What else should i look ifor?? is there some settings that i should set in VS 2010 Express
|

Try placing the
#ifdef __cplusplus
extern "C" {
#endif
#ifdef __cplusplus
};
#endif
in the CPP file also, surrounding the functions you want to export. I think that is the issue.

NO luck still....

I'm sorry. Maybe someone else will have some better ideas.

If possible can you just try downloading the code and check with your MS VS version??
|
|

I did. It won't compile because of a number of undefined symbols in SpiTest.cpp.

Compiler: Visual Studio Standard Edition 4.0
Language: C/win32
My program uses 10 edit controls three of which are read only and 2 push buttons. I am using the tab-stop style
controls. My problem is that when navigating the controls
with the mouse the program hangs after clicking each input
control about six times. If I navigate the controls with the tab key I don't have this problem at all. This program
performs calculations for building an antenna for amateur
radio use and includes a graphic of the antenna.
EDIT:
If I process WM_LBUTTONDOWN in the main window 40-50 times the program hangs. So it happens even if I'm not using the edit boxes. Sorry if I'm not making everything clear. The user
enters values and then presses the calc button for one calc and does the same for another
calculation. Two sets of edit controls and two push buttons.
