View 1 RepliesI dont get this. I use code from one project that works and paste into anther and now its full of errors.
I have no clue how to solve this (See attached image).All of the errors have to do with Excel and Outlook applications.The info for "Imports" section is the same as my other project and all the "Dims" are the same as well. (These are two separate projects).Basically, I copied a form from one app and made a stand alone app for that form.

View 1 RepliesI'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.
Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

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).

View 3 RepliesTo correct this error I use the given help that microsoft provides below and i am still getting the error messages can anyone assist me with the source codes if i send some code snippets?Check that the type definition and its reference both use the same spelling.
Check that the type definition is accessible to the reference. For example, if the type is in another module and has been declared Private, move the type definition to the referencing module or declare it Public.If the type is defined, but the object library or type library in which it is defined is not registered in Visual Basic, click Add Reference on the Project menu, and then select the appropriate object library or type library.
