To create and an Automation When I got the Class wizard I selected Create Class from typelib
I the selcted the excel.exe
The Wizard create a number of Class I slected to include all of them in my project
After getting a Clean build I decided to add some ole code
So I included "CAppliction.h"
I coded CApplication app;
however I got a whole slew of build errors

i am working for windows 8 wrapped credential provider .i did every thing in document which is provided by Microsoft .i implemented ICredentialProviderCredential2 interface with GetUserSid(__deref_out PWSTR *ppszSid) method,i am able to get sid .but my credential provider showing like other user tile ,but widows default credential showing password text box only,why my credential showing username text box and password text box. please help about this
my dll is custom credential provider .this dll provide a link in windows logon screen,this link will display win32 dialog with custom control.this is working for windows 7 32&64 bit and windows 8 32bit.but 64 bit windows 8 every thing is coming fine dialog only not displaying .
Problem is this || IID_ICredentialProviderSetUserArray when i call IID_ICredentialProviderSetUserArray interface through Quareyinterface dll is crashing without implementing ICredentialProviderSetUserArray interface dll is working is fine .
CSampleCredential **_rgpCredentials; // Pointers to the credentials which will be enumerated by this
ICredentialProvider *_pWrappedProvider; // Our wrapped provider.
DWORD _dwCredentialCount; // The number of credentials provided by our wrapped provider.
DWORD _dwWrappedDescriptorCount; // The number of fields on each tile of our wrapped provider's
ok but that is not problem when i called ICredentialProviderSetUserArray ==riid probblem is occurring
if (IID_IUnknown == riid ||
IID_ICredentialProvider == riid ||
Are you certain that the old object is not getting out of scope when you create new. When you create multiple objects, chances are that you are not maintaining reference counts correctly so there is a small chance that object is actually removed or marked for removal when client attempts to access ...
But for e.g. HrIsProtected() I need to provide an implementation of ILockBytes. Has anybody experience how to correctly implement ILockBytes in managed code? I am a bit at a loss as to what is expected here.
For unmanaged code I found a sample that uses CreateILockBytesOnHGlobal(). This returns an unmanaged instance of ILockBytes. Is there any chance of using this unmanaged instance from managed code (probably not...) or marshalling it into a managed structure? Or is there a similar method for C#? In that case I wouldn't have to implement ILockBytes, which would save me a lot of time.
Of course, I could implement this part in unmanaged code, but I'd prefer a solution in managed code, if possible...
Does any one knows how to compile COM for VB6, my application contain one .Fig file as interface and .m file containing code and
one Excel file for data.
My problem is how to compile all together in dll which i can call
I recently upgraded my project from .net 3.5 to 4.0. My Word Interop Assembly was working on client machines just fine in .net 3.5. After upgrading to .net 4.0 I changed the Embedded Interop Types property to false. Now some clients are looking for Interop.Microsoft.Office.Core when previously they weren't. My question is how come the clients are looking for this assembly with .net 4.0 when they weren't in .net 3.5?
I have created a class in c# to replace a vb6 class used in an asp web page. Note I said asp and not asp.NET. I am running this in IIS 7.5 on a 64 bit Windows 7 machine.
I compiled the program and all its support dlls as x86 and believe I got all the correct tags and check boxes for COM. I can create and use the class in VB6 but it still bombs in vbscript with can't create object. I found some articles on going to do tweaks in the registry to get it to work on 64 bit but alas no avail.
The web application will run with the old VB6 object just fine. The configuration is an application with a separate pool set to pipeline mode classic, no managed code, enable 32 bit applications = true;
Initially I was getting a can not create object when trying to use the new c# object but I copied the dll and its support dlls to the sysWOW64 directory and it changed it's tune to
MaxRecall.Shared error '80004003'
Object reference not set to an instance of an object.
/mr/mrq.asp, line 193
the structure of the project is thus
the object I am creating with createobject is dependent on a single assembly, MaxRecall.CORE, which is dependent on two assemblies, MaxRecall.CLIENTS and MaxRecall.Shared. None of the support assemblies are com exposed so this error is not a COM error at all I think.
MaxRecall.Shared is totally static with zero objects to create. It only had two static doubles that were class scoped that were not instantiated but I set them to 0 in their declarations. To my thinking there are no objects in MaxRecall.Shared to gain an instance to so the error is odd.
Sigh. Any and all insights are desperately welcomed. I cross posted this in the ASP.net section.
I hope I'm asking in the right place.
I don't have Win8 machine available and my computer can't run Win8 in a virtual machine, so I'm asking for help from someone with Win8 machine to find out why my code doesn't work in Win8.
I received request for a small project, namely Explorer thumbnail shell extension for OpenRaster (*.ora) files saved by the MyPaint application.
OpenRaster files have the same structure as OpenOffice files (*.odt, etc...), the thumbnail is stored as "Thumbnails\thumbnail.png" inside the zip file.
I've made similar thumbnail shell extensions before and I have working code from previous projects but it's a bit more complicated.
This time I got inspired by article I found here (Google translate FTW!): http://eternalwindows.jp/installer/zip/zip02.html
Apparently you can use CompressedFolder zip storage handler COM object (from zipfldr.dll) as described in the article, pretty elegant and lightweight even though it doesn't support Unicode file names inside zip.
My code finds and extracts thumbnail.png inside the zip and loads it with ATL::CImage.
I've made this activex dll (ATL project, source + 32/64bit binaries): https://dl.dropbox.com/u/61407853/orathumbs1002.zip
I use VC2008 Express + Win7 SDK + ATL7 headers (from WDK) and I started off with VC6 ATL project skeleton.
Everything compiles without warnings and everything worked fine both on XP and Win7 32/64-bit but I'm told it doesn't work on Win8 x64, the dll is registered and thumbnail cache cleared but no thumbnails are generated, and I couldn't say where's the problem without access to Win8 machine.
Here is a small Win32/ATL dialog project that tests the extracting code: https://dl.dropbox.com/u/61407853/ThumbTest.zip
Inside the zip is the source, compiled exe (debug release) and 2 test files (1 good and 1 with invalid thumbnail). The dialog accepts dropped files and shows the thumbnail if successful.
It pops up a messagebox with a description of HRESULT error and calling location in source file (just hit Ctrl+C to copy text from messagebox).
I don't know what is the problem, is my activex dll code broken or is the extracting code broken, do I need to compile with VS2012/WinSDK8 or something else, so if someone could help me track down the problem (compile and debug), it would be greatly appreciated.
My apologies if my post is chaotic, I try to describe in as much detail I can.
I would think you'd be extremely lucky if you found someone here with time and the setup to do what you suggest - not impossible, but a good deal of the inhabitants here do have day jobs

When I read these, I thought surely its no different from a standard deploy to (remote) customer setup - the bit you have missed, it seems to me, is trace/debug logging - can you log trace/debug statements/results (etc) to a file, and get that sent back to you ?
Ideally you'd also have a snapshot of the things like the event logs etc or a crashdump from the machine so you could analyse it
see i have created the com dll for shell context menu ..
if (DragQueryFile((HDROP)medium.lpszFileName, i, path, MAX_PATH))
szFileName = g_szSelectedFiles[i];
from here i am getting the path (szFileName )i want in exe code so that i can proceed this my doubt ..
the variable is decalred as static in header file of the dll .i link the library of dll .the scope is not remaining .....
the path(Szfilename)is useed in dll .Now this szfilename path i want use in the application code .
i explain how i tried i linked the dll lib to an application code and then i included the header file of the dll in an application code so that i can use the path(szfilename).
this szfilename is declared in static so its scope remain in application code also ..
I have the following code sequences whose pourpose is to display a .txt file in a Excel Spreadsheet, however the .txt file is not being loaded after I execute workbooks.opentext
a workbook is loaded but there are no sheets displayed let alone text
I get good return codes from IDispatch->invoke and good return codes in excpInfo
I have changed the file name to a bogous name and the same thing happens
Then you should provide a LPCTSTR in your call, rather than providing a LPCSTR, and then telling the compiler to ignore the fact that the string may not be in the correct format. Lookup the use of the TEXT() macro and make sure your strings are generated correctly, and read the documentation on the correct use of casts.
Use the best guess
