[2005] Pass Excel.Application Object To Shared-Addin By .Net?
Jan 22, 2009
I currently need to build a Automation Add-in for Excel. This add-in will load a recordset from Database to Excel. I would like to have function A() that I input in Cell as a formular. This function A() call a the add-in to load the data from Database to Excel. The data should be a matrix. So that means I would like to set in Excel worksheet a range of data by just calling single function in a cell. (I am sure there should be some way to implement it)As I know if I develop a shared Add-in by VB(or VB.Net) and in the add-in, I can get an Object of Excel.Application. By this Excel.Application object, I can get full control of Excel inside the Add-in. That means if I define a sub that load datamatrix from database and using the Excel.Application object I can populate the data matrix to the Excel.
I have done much research on internet and I now have built a shared Add-in for excel. I should say this add-in works fine without invoke the Excel.Application Object that I have tested. But when I call the Add-in function that invode Excel.Application Object from Excel I got an error as below:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Run-time error '2147467262'(*)
Unable to cast object of type 'System.String' to type Excel.Application

I'm trying to upgrade an Excel VBA workbook to a VSTO Excel Add-in in VB.NET using VS 2010. In the original (i.e.- VBA) version I have a modeless UserForm (called frmMain) that floats on top and is visible at all times while the user is still within the Excel application, but is not visible if the user moves to another window outside of Excel.
For example, within Excel the user can click on any worksheet tab, select any cell, etc. and the UserForm is still visible. This is exactly how I'd like it. The problem is, that in the new VSTO add-in, I can not get the Windows form to mimic this same behavior. I use frmMain.Show() to show the form as a modeless form, but the moment the user clicks an Excel worksheet (i.e.- activates a worksheet) the form becomes hidden behind the worksheet.

I've developed shared addin for Microsoft Word. I distribute this addin with my application and using Inno setup for installation. The Inno setup installs my application and then runs "myAddin.msi" file in order to install addin.

Right now, in order to uninstall addin, the user has to to it manually through control panel.

I am writting a VB .net (3.5) applivcation which references a COM object. I can call methods on the COM object fine provided that they don't require any variables to be passed. I have been told that you can only pass a maximum of one varaible to a COM object, I really don't believe that it true
for example
objsession.connect()
works fine

I have created a shared add-in in Visual Studio 2008 and using the shared add-in wizard and am coding in VB. When run the add in in Access 2003 I want to check if the user has a database open, so I set a AccessApplication variable to be the application object in the OnConnection procedure and then on a button click I check if AccessApplication.CurrentDB Is Nothing If there is no database open Access will close correctly after the button is clicked. But if a database is open then I have to stop Access in the VS debugger.

I wrote a C# Excel automation addin (Excel 2010 64bit, VS 2010) to provide some additional user-defined-functions in Excel. Now, the addin works fine besides the fact that the two methods "OnDisconnection" and "OnBeginShutDown". are not called when I close Excel which is a problem for me. Also, while Excel seems to shut down properly, the instance is still running in the background after the excel-window has disappeared. So, apperently the problem is that Excel is not shut down properly.

Just asking for personal preferences, pros,cons on the following situation. I have a class(classA) that has some shared members in it. I have a procedure in a form that needs to execute a function in a separate class(classB). This function requires some of the shared member values from classA. I can either pass these values as parameters from the form to classB, or in classB I can just access them directly by referencing classA. As a general rule I've tended to try to use parameters to pass all the information a function needs but it starts to seem a little unwieldly when passing several parameters to multiple procedures.

Problem:I am not getting the cursor (4 arrowheads) for moving the form.I am using the Panel1_MouseHover to display the cursor. Right now if I choose any other cursor then it is working but the same cursor also displays when I hover the mouse over any other control. I want the cursor to show only in the areas of the Panel where there are no controls.How do I show Tooltips for the images? The play,stop,next, previous,playlist,Hideme(with the smiley),volume are all images and not buttons?

I would like to automatize 1) and 2), so that the user just needs to run an exe-file in order to use the addin. 1) should be no problem, but how can one automatize 2)?

I've been trying implement Constructor method in passing variable between two forms.Just a rough user interface guide - issue Invoice. User would type in all the Customer Name, Document Number. Once he reached Item Details, a Child Form would pop-up for the User to select/search the Invoice's Item; Once selected, the selected item would showed in the primary Form.
What I had tried is, the Constructor method worked perfectly when it is self-contain in a new project, yet to be implement in my application.But when I implemented, there is an error: Reference to a non-shared member requires an object reference.

For some reason I am not able to use DoCmd.OutputTo with my access object in VB.net 2005. I get the following error: 'OutputTo' is ambiguous because multiple kinds of members with this name exist in interface 'Microsoft.Office.Interop.Access.DoCmd
I am referencing the Microsoft Access 12.0 Object Library and using Imports Microsoft.Office.Interop
Dim objAccess As New Access.Application
objAccess.OpenCurrentDatabase("C:Database.mdb", False)
objAccess.DoCmd.OutputTo(
A similiar command Docmd.SendObject seems to work just fine, so I don't know why I am getting that error or how to fix it.

With vb.net I would like to select 4 cells in Excel and then pass those cell values along with 1 button tag to a formula in Excel.I press a button with a month, say "May" as text. I want to grab a cell in Excel labeled "May1t" the value of which is the number of hours until may. This is the code I'm using.
xlsWB.Worksheets(2).Range(Month1 & "1t").Value I am able to set a variable with this as the value but,
I want to pass this cell (which will be updating as the time counts down) and 3 other similarly specified cells along with the button tag to an Excel formula.I have something like this:
Private Sub F_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles F.Click
xlsWB.Worksheets(4).Range("B2").Formula = "=MyFunction()"
xlsWB.Worksheets(1).Range(Month1 & "1t").Select()
End Sub
The formula takes the parameters in the order: MyFunction(Cell,Tag,Cell,Cell,Cell).

I am working on a application that has quite a few functions involved and have been thinking of the following: If I have a function that has a few paramaters, is it more efficient to pass the objects to the function(Example 1) or reference the objects in the parent(Example 2)? Does it matter if the objects are large or not?
Example:
Class mainform
Public myGenericList As New List(Of String)
Public myDatarowArray() As DataRow

The CLR has been unable to transition from COM context 0x1b3008 to COM context 0x1b3178 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time.To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during lonunning operations.

I've implemented the localization in my windows application with no problem for the label or command button which have a fixed text.
My problem is related to the label which text is merged with some variables or object properties.
E.g.: vb label1.text = "There are " & myDataGridView.Rows.Count.ToString() & " items"
So, how can I set (if it's possible) the localization for these labels? I've this kind of assignment in modules and not in the form. It's possible to set a resources file also for modules?

I want to create a subclass of a class that has some shared methods. These shared methods all call one specific method. But I can't redefine that specific method in the subclass. If I try to make it overridable in the parent class, it says that shared and overridable can't both be used.
