Jan 26, 2012
Im trying to get softehci.interop.dll to show up as a com library in vb.net how do i get it to show up because im trying to use it but it doesnt even show up in vb.net or i could use it as a dotnet library.Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth. - "Sherlock holmes" "speak softly and carry a big stick" - theodore roosevelt.

I have been doing a lot of reading on this topic and most folks seem to agree that having Excel is required to use the COM Interop libraries. However they are never specific as to where that should be installed. Does it need to be installed on the machine I am developing on or does it need to be on every machine that I deploy to?
Edit: I should mention that this is desktop development/deployment targeted for all Windows machines.

I have no intention of using "My" for anything in any of my projects. I haven't done anything with it (that I know of). But every one of class libraries shows a "My" namespace in Reflector and NDepend. This adds a lot of unnecessary clutter.
1) Why does it show up?
2) How can I remove it?

SQL statements:
SQL = "SHOW TABLES;"
Try
conn.Open()
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

This 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 have added it as a reference and added an Import statement

I then initilalise it with

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:
[Code]...
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.
I use this two classes , that compile and register OK. One Class QBitems return a nongeneric collection of QBItem but when I tried to use the Add and/or Remove Method, I receive the following error in Excel VBA :
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.
NEW: When I replace the QBItem object with a string in the Collection QBItems everytthing works OK. It looks like interface doesn't like to pass an object like QBitem class
Excel/VBA:
Sub Pru()
Dim obj As New CollectionCOMClass.SimpleClass
Dim Itms As New CollectionCOMClass.QBItems

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.

The Current Setup:So, I can use the following code to save a file as an XLS:
_myWorkbook.SaveAs("FileName.xls", Excel.XlFileFormat.xlWorkbookNormal)
I can also use the following code to save a file as an XLSX (Since I use Office 2010):
_myWorkbook.SaveAs("FileName.xlsx", Excel.XlFileFormat.xlWorkbookDefault)
I have tried (unsuccessfully) to save the file as an XLSX using the following code:
_myWorkbook.SaveAs("FileName.xlsx", Excel.XlFileFormat.xlExcel12)Why does this not work? Last I checked, Excel 12 was Excel 2007 (a version that supports XLSX). Am I missing something?
I get a This extension can not be used with the selected file type error)

I'm using the InteropFormsToolkit version 2.1. I'm trying to make sure that when a .NET form loads from an event being thrown on the VB6 form, that the .NET form can stay on top. I've tried many things and can't get anything to work. I've tried everything from z-index, to adding a managed call into User32.dll to push it to the forefront, etc.

I cannot get a handle for managed code to work for unmanaged code. I am successfully getting a a process handle on the managed side and sending it to unmanaged multithread code which is comming back with a zero which is supposed to be the old mask if the call was successful which means it wasn't. Im beginning to wonder if the structures are different. I also think that they are different list lists so of course it will fail.[code]...

I'm working on some interpo between VB6 and VB.NET and I've hit (another?) brick wall.I need to pass an array of "stuff" between VB6 and VB.NET. This contains an ADO recordset and 4 string values. There could be any number of these 5 items passed, so they will have to be an array of whatever.Seemed to me that in VB I should create a Type and in .NET a Struct, then it should be easy. However...
On running the VB app it fails to start with an error "Function or interface marked as restricted, or the function uses automation type not supported in Visual Basic"

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.
