Creating Windows Form Control?
Feb 24, 2011
I'm trying to create a windows user control project that has a textbox placed on it.I want the textbox to fill the user control window.I've built the control and added it to another project, but it isn't behaving the way I want it too.When I drag and drop the control from the toolbox onto a windows form and try to resize it, because the textbox.multiline property has been set to True, the Textbox resizes horizontaly and not vertically (just like normal textboxes do) however the underlying user control window resizes which is undisireable. How can I get the user control window to stop doing this.

I have another question (and anticipate that I will have about two more before I'm done with my class project). Here is my issue (and I'll copy and paste my code for clarification). I need to link up the control from the form on either side of the current form that I'm working on so that if I click on the buttons that I'm titling previous and next that I can click on the proper button and either go directly to the previous form or the next form. I was successful in doing this for two earlier forms on this project (with some direction from a couple of helpful people on this forum before), but for some reason, no matter what I details I use the controls do not connect to the previous and next forms.
Option Explicit On
Option Strict On
Option Infer Off

I have a project that will need several forms with a similar structure - a Data Grid View control, a few buttons and some textboxes. They are not similar enough to use just one form and change things programatically so I would like to create a "template" and add several copies of it into my project. My first attempts have failed miserably, ending up with lots of "conflicts" and "duplicate items".
So, how should I save a form from my existing project in such a way that I can then load in multiple copies (giving them suitably different names) without having name conflicts?

I am working on a project. Part of my project requires me to capture data, for example, email address, from certain rows/columns of a datagridview(form2.vb) and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). The problem is the datagridview on my form must be able to display databases by making a connection to Microsoft SQL Server 2005 but so far, i have not been able to do that. I have seen many codes with regards to my problem but i do not know how to implement it.
Below are my codes that i have written so far. My program's limitations are not being able to display databases from Microsoft SQL Server 2005 so i created the statement below to add columns and test my codes.
DataGridView1.Columns.Add("CustName", "CustName")
DataGridView1.Columns.Add("Email", "Email")

Suppose I have a label control on a windows form called "UserName". How can I refer to that label programmatically using the label name? For example I can do:
For each ctrl as Control in TabPage.Controls
If ctrl.Name = "UserName" Then
' Do something
End If
Next
This seems quite inefficient. I would like to do something like: TabPage.Controls("UserName").Text = "Something" I did some googling but couldn't find a satisfactory answer. Most suggested looping, some said .NET 2005 doesn't support direct refenece using string name, and FindControl method was asp.net only...

I have a VB windows application and I need a way to control input output from this windows application to a batch file.The batch script is quite complex so converting to a VB console application is out of the question because it will too much time.An simplified example is this:I have this batch file test.bat(just for example)
@echo off
set /p choice=name : %choice%
echo Hello %choice%!
In this batch file the user input the name which is then stored in a variable and after the user press enter on the screen will appear Hello + user input.
1. Is it possible to enter the name in a textbox from the windows form and by pushing a send button pass the name to the batch application and then the batch file to continue the operation of displaying the Hello message?
2. After the batch file finishes the operations it will open another console windows (3) with status of the various operations that take place on the system(in my case connected users to a server)Is it possible to hide this child console windows that are generated after my main .bat application finished the operations of opening connections?Can this be done from the windows application or I need to modify the .bat script?
3. Is there a way to collect the console windows output in a textbox from the windows application?One idea that came to me was to redirect the console output to a textfile and then read the textfile in the VB application but I want to know if there is another way.
4. Is it possible to hide this batch file inside the windows application exe?

I have a spreadsheet control on a windows form that I would like to populate with data from an existing worksheet (myworkbook.xls, sheet1). The best solution for me would to be to actually open the workbook on my form (not sure that is possible?), the next best solution would be to fill the spreadsheet control.

I have a customer which as a Visual Basic Project in single instance mode with a wired presentation logic.
The main form contains a TabControl with mutliple TabPages.If I click on TabPageA another form is shown in front of the Form and resized to have the same size as the TabPage.
If I click on TabPageB the first form is hidden and another form is displayed.So basically for the user it looks like you have a TabControl with different TabPages which is not the case.
I tried converting the Forms to UserControls and put them inside the TabPage, but, thanks to the SingleInstance app, this would take a whole lot of refactoring. I tried it but eventually gave up because of many many runtime errors and I don't want to put any more effort in this.

I am writing a Windows form application where a client has the ability to add as many chart as needed in the form by clicking at an icon in the menu bar at run time. These charts will have the same format, and I will have them linked to a text box for the client to select which entity to chart.I have no clue where to start. I did a web search and I have found articles that show how to add user's control at design time (I don't think it is what I want).

I'm trying to create my own control to build a custom planning on it.After trying it with loose controls I got an error but after advice on my previous post, I redraw everything.I have now the header of the control finished, the header shows the days of the month for as many months that fit in the window.Now I want to put the list of data below it, but it will be more than the windows height, so I need to have a scroll bar that will scroll the data but not the header.I would not like to design my own scrollbar and rather use the scrollbar control for it, but when I put it in, I cannot use the NEW keyword.example:
Dim sb
As
ScrollBar
with this I get the error message: 'New' cannot be used on a class that is declared 'MustInherit'.How can I get a scrollbar on my form to scroll the list only (so not the header)?

I'd like to use a TreeView control to display database data in a windows form with VB2008. All the information what I found is related to a website design, but I'm working on a database program (sql2005), where I'd like the user to see the structure what he/she make up with a TreeView like control. Just something like that when you explore your hard disk. How can I do that?

I have my forms all set up, I want a button on my main form that says Volume. When clicked it either opens a window above the current form with a volume control. Or opens another form that has the volume control in the center. When the slider is moved up to 100% windows is at 100% volume, when moved down windows volume moves down also.
