I'm currently trying to delete data from a dataset/datasource/database using visual basic. So here is the run down: I've built a program that can add, delete, and modify customer information from an Access database and I just got the add function working. Meaning, I can now add customers to the database and it is sticking to the database. I re-ran the program and even restarted the computer the computer and the data is in the database. This works fine. However, now I want to get the delete button working but I'm not sure why it isn't deleting some of the fake entries I made just to test out the add feature.Here is the code I am using:
Dim delCompany As UMD3.CompaniesRow delCompany = UMD3.Companies.FindByCompany (NOT SURE WHAT GOES HERE) delCompany.Delete ()
I have a listbox that loads all text files in a set folder on form load. From those files in the list box, I want to permanently delete a file from my pc, thru a button that I'll eventually add a yes/no msgbox before deletion.

I have a form with a datagridview on it. I would like to use the same grid with two different datasources (not at the same time). If I call the form this datagridview is on with one routine, I want the source to be a list (of Class). If I call it from another routine, I want the source to be a dataview. The problem is once I set the datasource the first time, it keeps that same source even when I try to change it. I'm using this code in the form with the grid:
[Code]...
I can pick either one of these and they work, It just doesn't change if I run it again with the other one.
if anyone had managed to configure BDP as a datasource inside Visual Studio 2008 ? I have added references etc and can query the database at runtime but I seem unable to configure it so I can add it at design time to be able to use LINQ etc, if someone has managed to do this can you let me know how as having to manually check tables etc outside of visual studio is time consuming.

I can't get is to save variables permanently. For instance, say you run your project and in the source code you have Button1_click s=textbox1.text (s is the variable I declared) Button2_click s=label1.text. Say you type some thing into textbox1 then click button1. Then you click button2. Is it possible to make it that the next time you run the program the text you typed into textbox1.text last time is displayed when you click button2? I am using windows form.
at my collage we have to rename all buttons and labels to represent the type of thing the button, label or text box etc do For instance if I had an OK button I would change the Text and (Name) of the button in the Properties section from Button1 to BtnOk, if it is a Label I have to change it to LblOk etc I was wondering if there is a way to change the default (Name) Button1 to (Name) Btn1 and so on so that I only have to click on the 1 and type my description, rather than having to type the abbreviation for the type of object every-time also ?
created a class that adds a TextBox with some custom properties to the toolbox. But it's only available when the project I created it in is opened itself. I'd like to have available it in the toolbox at all times.
I made a customized TextBox that I'd like to permanently add to the toolbox. But when I close the project that I created it in, my new control also disappears and I have to copy/paste or import the class-code every time I want to use it. Is there a way to get the control in the toolbox "forever"?I tried to enclose the class in a "Namespace CustomClasses" statement and changed the root namespace in the project properties to "CustomClasses", but nothing of what I tried is permanent. I prefer to store my classes in a "real" root namespace, in the same root as the microsoft and system namespaces.
Im using the webbrowser control in my application, but i want to permanently change the user agent when im navigating to sites.
I have tried the extended use of the .Navigate function for the webbrowser, but when the user navigates the browser, or when im beeing redirected by the site it goes back to the vb user-agent info.
Alternatly: Is there any way to catch the postinfo and http headers when the webbrowser control navigates to a new url?
I need to permanently store a string or maybe a object in my application. And yes, I have tried the application settings (My.Settings).
My.Settings.something = "hi" will save "hi" into something, and when i use msgbox to output the data, it works. The thing is; when I copy my application to somewhere else on my computer it is gone. I guess the settings is saved to some file at the filesystem, and when I move my file it also creates a new settings file. How can I store a string inside my application, and also move the application later on?

I binded a datagridview with datasource, But its order was changed then I used Columns("ColumnName").DisplayIndex property to arrange the columns of DatagridView. Now I am exporting this DataGridView to Excel, All things are right but problem is about the column positioning, Columns in excel file are shown in wrong order (it shows order before I applied Columns("ColumnName").DisplayIndex property to arrange the columns of DatagridView). My question is that how I permanently change the Column index of DataGridView......?
Public Sub gererateReport(ByVal dg As DataGridView) Dim oExcel As Excel.Application Dim oBook As Excel.Workbook Dim oSheet As Excel.Worksheet Dim oMissing As Object = System.Reflection.Missing.Value [Code] .....
I created some custom controls which I use quite often and I thought if I add them once to my ToolBox they just will be there next time I start up VS2008; however, that does not seem to be the case! Each time I start VS2008 I have to re-add that controls (which is quite annoying!). Is there a trick / way of having them there permanently?
I'm trying to figure out how to do this as I'm not sure what's the proper way of doing this.

1.) I dragged my detail view over to the form window to create a bindingnavigator, fields, etc.When I press save on the form, the database is temporairly saved.However, if I save my visual basic project, I lose all the changes I have made to my database.Is there a specific save command that updates the access file permanently?The default command added by dragging over the dataset does not work.
2. My database is accessed with the following string:[code]However, doesn't this mean that the database MUST be placed in that specific folder on any PC? Is there a way to simply build the database into the compile so the program automatically generates the database when installed on anyones computer?
3.) This might be fixed by fixing the previous two issues, but if I compile my program and try to install it, I get an error message "Could not download the application.The application is missing required files."

I've done most of my testing under vb2008 debug. Now that I'm doing higher level testing with the executable I've found that I have to set the build output path every time I start the project - in fact, If I don't keep the project properties window open, I have to change the path back after every build.
I'm working with several projects whose executables interact, therefore I am constantly switching projects to tweek one of the other modules and I have to configure the build output path again every time.
Is there a way to tell it to remember the path "permanently" until I change it?
This works fine, unless I have Windows Explorer open and I'm looking at the 'MySubFolder' directory. Then I get an IOException The directory is not empty. - clicking OK dismisses this and then the folder structure is not deleted. Any thoughts on how I can get this to perform correctly (i.e. delete), even when running this code while having the folder struture open in Windows Explorer?
