Its a good idea. But how do you do this in VB.NET Window Form Application? Can you give me some sample solution?

Exactly what I said. Add a settings file to your project properties. These get added to the app.config at compile time, but if you have an instance of this class, you can change the settings and call the save method to update the app.config

Ok,thank you Mr.Christian Graus. Sorry to disturb you about this my friend. I'll try to find it out. Sorry~~!

Look under MyProject in Solution Explorer, enter the setting under the setting tab
In your code use My.Settings to modify the user settings - once you find them they are really simple.

I'm sorry,can you give me further explanation about this? What code should be include for changing the value in my app.config file?
|
|
|
|

Did you read the response, do you know what Solution Explorer is, have you opened the VS IDE? 
Read the bloody response, try and follow what was suggested, I told you want to type in you code My.Settings. Intellisense will do the rest for you.
You don't manipulate the config file directly you use the My.Settings class to do it, it's built into VS, use it!

Yes,I am still running with my Visual Studio 2003 here. I didn't found any Setting tab on my Solution Exlporer. This is the things I create inside my Project now>> 2 Form, 1 Module and 1 App.Config file. And another Reference file which auto generate by VC2003. So,what should I do next my friend?
|
|
|
|
|
: Look under MyProject in Solution Explorer
NOT Settings tab that is under My Project - btw try double clicking.

This is all the file inside my Solution Explorer. What should I do next to create some files or add in any code?
Thanks~~!

I'm wondering if someone might be able to help me. I've spent a bunch of time on this, read everything I could find, but still can't seem to crack it.
I want to load an assembly .dll into a separate appdomain, from the root directory c:\.
The assembly asm is loaded into the new appdomain fine, BUT ONLY IF ShowForm.dll is in the application default path. I've monkeyed with Applicationbase to request that the load look elsewhere, to no avail. Do I need to specify a security policy?
In any case, is this really the way to load an application into a new appdomain (one which I can subsequently unload)?
Thanks in Advance
Dim Asm = System.Reflection.Assembly.ReflectionOnlyLoadFrom("c:\ShowForm.dll")
Dim ads As New AppDomainSetup()
ads.ApplicationBase = "C:\"
Dim ad As AppDomain = AppDomain.CreateDomain("App2", Nothing, ads)
Dim Asm2 = ad.Load(Asm.fullname)

I need to create an application in VB.net that will be used for printing sheets in a printing press company. the critical points that are required are:
1. The placement of the printing figures and characters on the sheet has to be very precise.
2. Printing of rectangles with rounded shapes with exact precision.
Will this be possible through a reporting tool or is there any 3rd party tool in VB that I can use?
|

You can do this with your own code. Any code will print with precision of location. The issue is how precise the hardware is that feeds the paper through.

The client will be using HP laser printer. Can you give me a clue on how to do all this with my code?

Again - the code will position with accuracy, they are at the mercy of the sheet feeder on their printer.
You can't NOT position stuff exactly. The problem is the printer needs to feed stuff exactly.

Hello. I am working with VB.Net in Visual Studio 2005 in a PC Windows Forms project. I have a DataGridView control that has a checkbox column. Some of the rows in the grid are not valid to have a checkbox. My hope is to have a column where, based on the value of a field in the row, the column sometimes contains a checkbox and sometimes contains a link. Has anyone done this or have an idea of how to do it? I've done something like this in a web project before, but the DataGridView is a very different control and does not appear to be as flexible. Any advice would be greatly appreciated.
|

This would require you making a couple of controls. One would be a composite UserControl that would show either a CheckBox or a Link control, then second would be a custom DataGridViewColumn implementation that uses the first control and supplies all the checks required.
This is a large undertaking. Creating a custom DGVColumn is not something you're going to get described in a couple of forum posts. It's really quite alot of work to get it working. Here[^] is an example of hosting a datetimepicker control in the DGV, but there is very little explanation of the code.
Normally, you wouldn't have two seperate controls representing values in a table. Either the column in the table is a boolean column, or it's not. What you're describing is pretty unusual.

I know it's kind of an unusual situation...My grid contains records that have a status of open or closed. When the record is open, the checkbox is valid to be checked and actions performed on the record. When it is closed the user must first "re-open" it. In terms of functionality I can have the re-open feature in another column or somewhere else on the screen, but the screen is already very busy and it seems much more natural and user friendly to combine it with the checkbox column.
Although I think you found exactly what I was needing, due to time constraints, I will not have the time to make my own custom DGVColumn. I had a thought the other day as something of a cheat or workaround. I'm going to play around with making an image column and displaying an image of a clear checkbox, checked checkbox, and underlined word to represent a label. Hopefully it won't look too weird or different from an actual checkbox column.
Thank you for your advice and help on the matter.
