Are you implicitly or explicitly linking with their libraries? Have any global OpenCV-related objects been declared?

I have global declarations of opencv classes and I am using "additional dependencies" section in Linker options.

Classes or objects? Global objects will be instantiated before your "main" function gets called. That may be where the error is happening.

Basic question. I assume you managed to build the OpenCV libraries and/or DLLs successfully? Also, do you know about the OpenCV support group on Yahoo Groups? You may have better luck there since it's a specialized support group.
You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.

hi, maybe already is late, but like aditional information, i got the same problem and i solved, a had put cv210d.lib; cvauxd.lib; etc. in the entry of Link in properties window, I erased the letter 'd' cv210.lib; cvaux.lib; etc. and the message "The application was unable to start correctly (0x0150002)" no appeared other time.

Hello
Is there anyway to force the background of a dialog to be visible? For some reason all my dialogs have lost their bgs although I can't find a call within my code that uses WM_ERASEBKGND.
In order to see whether if was the dlgs themselves, or something else I constructed a basic one. It was created using all the default settings in the VS resource editor. The problem still occurs. I can attach the code for this basic dlg but the post will be quite long.
If there is no way to force the background to be visible, does anyone have any idea of what might have caused this? The buttons and other items in the dlgs are visible, just not the background or title-bar.
Many thanks in advance for help offered.

So what is visible?

Visible:
- buttons
- text in text-boxes (editable and static)
Missing:
- dialog background
- text-box background
- static-text
- title bar
Other:
- space where dialog background would be renders whatever is immediately below it
- space where text-box background would be renders desktop background
Hope that clarifies enough to assist

I'm clueless. It almost sounds intentional rather than accidental. What version of VS are you using?

Did you set the property "transparent" to true?
|
|
|
|
|
What is the border property of your dialog box?
If it is None, change it to Dialog Frame.
|
|
|
|
|
I would also ask:
Does (eg) notepad show this problem too, if you use the help | about box?
If other programs are fine, then it's something you did. Make a copy of your project, and start ripping out whole sections until you find the "clever" thing you did at 2am while drinking too much beer last night...

Hi All,
I really need help on working with USB. I cant find the answer anywhere
and I am starting to get really frustrated.
My problem is that I am trying to get a handler for a USB device so
that I can read/write to it. I was already able to compile my project using
Visual Basic 2008.
I followed these instructions to get Visual Studio 2008 to compile using winUSB libraries.:
1. Get Windows DDK.
2. Copy the following header files from DDK directory to your project
POPSHACK.H
PSHPACK1.H
SETUPAPI.H
usb100.h
usb200.h
usb.h
winusb.h
winusbio.h
3. Get Visual Basic to use those header files and pertinent libraries by:
1. Project > YOURAPP Properties --> C/C++ > General > Additional Include Directories : PROJECT_DIRECTORY
2. Linker > General > Additional Library Directories : WINDDK_DIRECTORY\lib\wxp\i386
So now everything compiles perfectly. But when I run my code, setupapi is not returning me the Interface Data.
I know the device is physically plugged in.
I know the GUID ID is valid because is written in the INF File which installs winUSB.
I verified that Windows Registry knows the device is there, and also verified the GUID is the same.
I verified Device manager sees the device with WinUSB driver and it is not showing any problems.
This is the code I am using. I took it from the How to Use WinUSB document
written by microsoft. I marked where the Interface is still empty.
<br />
BOOL CUSBDevice::GetDevicePath(LPGUID InterfaceGuid, PCHAR DevicePath, size_t BufLen)<br />
{<br />
BOOL bResult = FALSE;<br />
HDEVINFO deviceInfoSet;<br />
SP_DEVINFO_DATA deviceInfoData;<br />
SP_DEVICE_INTERFACE_DATA deviceInterfaceData;<br />
PSP_DEVICE_INTERFACE_DETAIL_DATA detailData = NULL;<br />
ULONG length;<br />
ULONG requiredLength=0;<br />
HRESULT hr;<br />
<br />
deviceInfoSet = SetupDiGetClassDevs(InterfaceGuid,
NULL, NULL,<br />
DIGCF_PRESENT | DIGCF_DEVICEINTERFACE);<br />
if (deviceInfoSet == INVALID_HANDLE_VALUE){<br />
return bResult;<br />
}<br />
<br />
deviceInterfaceData.cbSize = sizeof(SP_DEVICE_INTERFACE_DATA);<br />
<br />
bResult = SetupDiEnumDeviceInfo(deviceInfoSet, <br />
NULL, InterfaceGuid, 0, &deviceInterfaceData);
<br />
<br />
if (bResult == FALSE){
DWORD tError;<br />
tError = GetLastError();
<br />
<br />
return FALSE;<br />
}<br />
<br />
SetupDiGetDeviceInterfaceDetail(deviceInfoSet,<br />
&deviceInterfaceData,<br />
NULL, 0,<br />
&requiredLength,<br />
NULL);<br />
<br />
detailData = (PSP_DEVICE_INTERFACE_DETAIL_DATA)<br />
LocalAlloc(LMEM_FIXED, requiredLength);<br />
<br />
if(NULL == detailData)<br />
{<br />
SetupDiDestroyDeviceInfoList(deviceInfoSet);<br />
return FALSE;<br />
}<br />
<br />
....
<br />
<br />
<br />
Thank you everyone, I really appreciate all the help i can get.

Use CreateFile() to get the handle. You can then use ReadFile() and WriteFile() with that handle.

Hi, Thanks for your responese but could you elaborate a little bit more?
The device I am trying to connect is my own.. and I have read that to be able to do that
it needs to be a generic device, like a COM1 port or a HD device.. how do I open it as a file
or what would the file name and location be?
Thanks!

Have you tried:
CreateFile("COM1", ...);

Hi ,
I am using MS Access Database . Which has GUID as its one of the column. I have to fetch the data from this database using supplied GUID's . I have written the query like this
SELECT * FROM Images WHERE GUID = 'First GUID" OR 'Second' OR .. ..OR .. OR
This query can be long to N numbers of GUIDs passed. This query is working fine. But I have the doubt whether this query will fail at certain point due some buffer or limitation on query lenght. Is there any limitation on Query Length. Is there any other solution to make this query compact ??
Thanks in Advance

Hi,
I have a dialog with some edit controls and a property sheet with three pages. When we take the dialog the focus is on one of the controls in dialogf outside the property sheet. when i switch the focus using tab key, the focus first goes to the controls inside the sheet and at last comes to the tab of the sheet. but i want the order such that it should first go the tab before going to the controls inside that. Please tell me how i can do that.

If you are using resource editor, you can set the tab order there. It is available in "Layout" menu in VC6 and "Format" menu VC9. Shortcut key is Ctrl + D (in VC6 keyboard shortcut map). Then you can see the tab order indication for all controls. You can click on each controls to sequence.
If you are creating the controls dynamically, the creation order sets the tab order. You can change it by using SetWindowPos().

I want to be able to #define CSHARP if the dll detects a c# app, and not define it if its c++
if there is another way of doing it I would be open to that as well... I just cannot afford the time it takes to change this each time i build it with a different application
#define CSHARP
#ifdef CSHARP
typedef void (__stdcall *callBack)(unsigned char* buffer, int size);
#else
typedef void ( *callBack)(unsigned char* buffer, int size);
#endif

Do you build two versions of the same DLL? Really?
