Dim objWorkBook As objExcel.Workbook = CType(objExcel.Workbooks.Add, objExcel.Workbook)
Dim objWorksheet As objExcel.Worksheet = CType(objExcel.Worksheets(1), objExcel.Worksheet)
I am back with new problem using TabControl in VBNET2008 Window Application I am trying to figure out how to determine logically either TabPage1 or TabPage2 header button is clicked on.
The TabControl has 2 Pages:
TabPage1 Text = Display Orders
TabPage2 Text = Edit Transaction.
I need to know which one is clicked on in order to write the routines.
We are currently running a 32-bit VB.NET 2005 application with a 32-bit SQL 2000 data store. The network guru is going to be upgrading the server and SQL to a 64-bit version on both. Will the 32-bit application still connect to the 64-bit data files? I am guessing I will somehow need to tie in the 64-bit drivers somehow, but will those work on a 32-bit development system?
View 4 RepliesI wrote an application in VB.NET 2003 and would like to upgrade and use VB.NET 2008. Is there anything I should know before hand when converting my application from 2003 to 2008? Didn't know if it was like converting a VB 6.0 application to VB.NET.
View 2 RepliesI have an application that was developed and is maintained in VB.NET 2003. Is it possible to convert the 2003 files to Visual Studio 2008 and maintain the program in 2008? If so is this fairly easy to do?
View 4 RepliesI am trying to retrieve the data from EXCEL 2003 spreadsheet from row 8 onwards because from Row 1 to Row 7 the row is merged columns from A1 to K1, A2 to K2, A3 to K3, A4 to K4, A5 to K5, A6 to K6, A7 to K7.
View 28 RepliesI am back with new problems relating to TabControl Page. On the TabControl there are 2 Pages which are : PagDisplay - Contail DataGridView (ReadOnly)PagEdit - Contain TextBox controls for editing data from PagDisplayThe System Analyst specification is after editing the data at TabPage2 when the user click on PagDisplay on TabControl it will activate the Function FCheckData to validate all the textbox data on PagEdit. If there are invalid data, Function FCheckData will return FALSE.When FCheckData = false, it should return to TabControl1.PagEdit page but I don't know how to do it. Here are the incomplete coding.
dim bolEdit as boolean = false
Private Sub TabControl1_SelectedIndexChanged(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles TabControl1.SelectedIndexChanged

Final step in my application. I finally got all the requirements working, but now I need to have the application run in the background.
The application was written in Visual Studio 2010 VB, Win form app.
The requirements are as follows:
1.) run the application at start up
2.) no icon
3.) always in focas
4.) always runs in the background.
Here's the full code I have right now (working! whahoooo)
Public Class Form1

View 1 RepliesMy boss gave me an MS Access application that was developed by our former colleague. He wants me to convert that application to VB.Net Windows form application. I went through the MS Access Application. It contains tables, queries, forms, reports and macros. I could not find the programming (Where is the code written in MS Access?). My boss wants the windows application to be same as the MS Access Application (both in design and logic). I don't how will i develop the windows form. How can I achieve this?

I have been developing a VB 2008 application which has been using Access as its database. The app is very far a long with about 30 forms and 45 DataSets I now must change the application to use SQLServer. Unfortunately all of the Table & Attributes names have changed in the new DB. Almost all of the data model has stay the same.
I have a few questions on the conversion.
The ConnectionString is currently pointing to the Access DB. I have entered the new ConnectionString into the Setting tab. What is the best approach to make the change?
I have done some testing to change the Table & Attributes names by using Quick Replace. It seams that sometime when I would do the rename I would lose the TableAdepter on some screens.
What is the best approach to performing the renaming task?
After converting a Asp.net website to web application, I receive 'Type MyNameSpace.MyMaster is not defined' error on pages that use the MasterType directive.

Public Shadows ReadOnly Property Master() As MyNameSpace.MyMaster
Get
Return CType(MyBase.Master, MyNameSpace.MyMaster)

Basically I have an application that has 2 textboxes and a button. What I am trying to do is when the button is clicked, it takes an entered string from box one (which is validated to only accept numbers) adds 235 to it then converts it to hex and finally reverse the string and sets textbox two equal to that value. Note that the final string has to be eight digits so the string may needed to be padded with zeros before the string is reversed. With that said how could I go about doing this? Also I do plan to add 2 more textboxes and another button to undo this process but I am thinking if I can figure out do it one way writing the code to undo the process shouldn't be too hard.
View 12 RepliesI have an application that I created a while ago. It's a forms based application that runs on one of our servers at work. The app works well, BUT at the moment, requires someone to manually run it, which means having the admin account always logged in, but having the server locked.Although it's a forms based application, for the majority of the time I don't need to see the forms, so can I safely make this run as a service (by adding the appropriate code), and hiding the forms?Also, is there some code I can put in to test whether the instance of the program was started as a service or from a user double clicking on the icon? If so, I'd like the user initiated instance to run with the forms visible.
View 2 Repliesmy goal is to
1.Take an file(exe,dll,etc)
2.Convert it into hex
3.place that hex values in a stack
4.Execute the values inside the stack to its original form(i.e. take the elements out of stack and then convert it to a compile format)
Imports System.IO
Sub Main()
Dim fileName As String = "ABC.exe"

I have what might be a dumb question, and/or discussed at length back in the 2005 days, but I could not find anything on it. Sometimes Google Fails me I am moving a old vb 6 application to .net and I hit a roadblock on ADODB. Now I used the converter to see what the effort was going to be and the first thing I noticed was that I could no longer bind my Text Data source like I used to.

I have visual studio 2010 Ultimate, but I cant convert a vb6 project easily. I just downloaded and installed the vb2008 express because I know it should have the capability to upgrade/convert it with reasonable accuracy.
I am getting this error:
unexpected exception occurred during upgrade engine operation: not able to bind to the source (exception from hresult: 0x8004000a (ole_e_cant_bindtosource))
I was converting my VB6 codes to VB 2008. There is a section i use a third party application (Microsoft Excel) to print report. But now VB 2008 is not accepting one of my statement. the statment is shown below in bold letters.
oSheet.range("H" & Row & ":" & "J" & Row).Value = Array(InvoiceNo, , Today)
it works in VB6 but fails in VB 2008 because of the Array statement, is there any replacement for this in VB 2008.
I have been converting my VB6 programmes to VB 2008. many of the problems that came up I have been able to solve; mostly by trial and error. However, I have one problem that was easy to handle in VB6, but I don�t see how to do it in VB 2008. I have checked Google, but didn�t find anything exactly similar to what I want to do.
On my form in VB6 I added two text boxes, each with it�s own name. I then copied these two and pasted them back onto the form, under the original textboxes, 5 times. Each time I was asked whether I was creating an array; I confirmed that I was.
I could then code as follows:
For x = 1 To 6
BidderName(x) = txtBidderName(x)
BidderCommunity(x) = txtBidderCommunity(x)
[Code]....
I tried to do the same thing on my VB 2008 form, but it does not ask whether I was creating an array, and in fact the array of textboxes on the form, is not an array!
how I get around this. The form has to show an array of textboxes, which are entered in order.
I converted vb6 project to vb.net 2008 but I got some error first one :Name 'VarPtr' is not declared.I got this one two times :Value of type 'Projectname.Func.EXPLICIT_ACCESS' cannot be converted to 'String'.
