Where can I get some good advice on using the IMAPI2.dll. Pickens are very slim and limited in VB 2008 Pro, and if there is an abundance, I just haven't came across it yet. I will follow-up on all links. My OS is Vista, and everything is up to date, except me.
View 4 RepliesI start making program that will burn CD/DVDs, and everything is okay. I found way to burn with IMAPI2 API, but now I have problem: I can't get progress bar of that burning.
Here is code:
[Code]...
I'm trying to understand how to route the events of my IMAPI2 burning progress but not sure how to do it. I've coded event handling before, but just not familiar with the IMAPI2 library so having some trouble.
This is their sample code in c#:
[Code]...
I am implementing IMAPI2 into my vb.net project but ran into a wall. I am getting the message Unable to cast object of type 'IMAPI2FS.FsiStreamClass' to type 'IMAPI2.IStream' when trying to start the burn. I googled around and found this is something that microsoft hasn't fixed.. which basically renders IMAPI2 useless in vb.net.
I found a post on codeproject.com by eric hadden who combined the IMAPI2.dll and IMAPI2fs.dll into an c# interop file. I also see the IBURN interop in microsoft SDK samples. I'd like to use either, but it's in c# and I'm using vb express. Does anyone know a way to get the interop into visual basic or a way around "Unable to cast object of type 'IMAPI2FS.FsiStreamClass' to type 'IMAPI2.IStream'"?
Am using visual studio 2010 vb. Using .net have added a reference to microsoft.office.interop.outlook type=.net version 12.0.0.0 copy local = false path = ...microsoft visual studio 10.0/../pia/office12 Using regasm.exe microsoft.office.interop.outlook.dll I have registered this assembly. Using the /regfile option I have viewed the contents. The clsID that it can't find ( CLSID={0006308B-0000-0000-C000-000000000046}) is not in this regfile. I would think that it should be.This classID on the MSDN site brings me to the Office 2010 Outlook.Namespace Class. For Office 2007 no clSID is listed.In the GAC there is microsoft.office.interop.outlook.dll version 12.0.0.0 is registered.When I run my application I get the above runtime exception.
View 3 RepliesThis might be a bit of stupid question but I need some clarification. I'm somewhat new to .NET and have created a EXE that had to reference an existing COM DLL. In doing so, Visual Studio 2010 automatically created an "Interop" DLL that it needs/uses to work with the legacy COM DLL.
I have deployed my project and included this Interop DLL with it (in the same folder) and everything is working fine. However, I have other applications that will need to use this same legacy COM DLL. Is it okay to reference it they same way in each application and keep deploying the "Interop" DLL with each application? Unfortuantely, all of these small applications go in the same folder and each use the same Interop DLL (so it will already exist there if it's used by another app.) I'm forced to having them in the same folder because these applications are being called as a way of customizing a parent application. As such it only looks in it's local folder when it wants to run a "custom" app. I'm just concerned if one the EXE's is ever removed and they take out the Interop DLL, then the others that still depend on it will fail.
So, I was wondering if it is possible or a good idea to put that Interop DLL in the GAC? I went ahead and installed the Interop DLL into the GAC and then removed the Interop DLL from the folder where my EXE runs and it failed to work. I get an error that says "Could not load file or assembly". I'm stuck on getting this working.
Do I need to reference the Interop DLL in my project differently such that it's now from the GAC? or Do I need to add something to my .NET code like Assembly.Load to make it work? Do I need to create that Interop DLL myself using TLBIMP?

I'm kinda new to using VB.NET and certainly with the Excel Interop.I have the impression that I'm doing something wrong in these simple procedures. I keep getting errors on them:

The first procedure fills a combobox with all the worksheet names of the workbook.The second procedure copies all cells in the selected worksheet to an array.The error is the following: System.NullReferenceException: Object reference not set to an instance of an object.I think the error is in the cleanup part, when I set the objects to nothing and close everything. Can someone confirm if this is good or wrong code and maybe point me in the right direction?
I Programe a COM Library in VS2008 to use in Excel , but I'm stuck with an error that I don't understand.

Run-time Error '438': Object doesn't support this property or method.
I added a class (SImpleClass) in the library and I called from VBA it returned the QItems collection without problem.

I have a .NET application that interops with a VB6 COM DLL. After installing the application on a Vista machine, I try to execute the code that consumes that COM component and I get an error attempting to read or write protected memory. The system's DEP is set to only essential programs and services, but apparently that automatically applies to .NET applications. When I tried to exclude the application from DEP, it said that DEP must be on for this program (could not be turned off). I had to use the bcedit.exe program to manually turn DEP off system wide and then reboot. After that, the application ran without a hitch, but this is not the route we want to go for our users. Are there any solutions/recommendations for this? It seems as though DEP has been more of a headache than not.

I'll like to know something about the option "Register for COM interop" into the project Compile screen from a project.
Is this check box do the same job as RegAsm.exe?
I'm asking this because since I've enabled this option the compilation of my project take 30-45 seconds instead for 2-3 seconds. And I've really need the .tlb file.
If the RegAsm program do the same job, then I will only rebuild my .tlb when needed instead of every compile.
