Show the trouble code and someone might be able to help some. But don't expect anyone to do your homework assignment for you.

MenuStrip Question

I have an MDI application. The parent window has a MenuStrip (MS1) with the common commands, and the child window has a menu strip (MS2) with some specific commands.

When the child window is maximized, the commands from MS2 are correctly merged into MS1. However, the menu strip itself still gets rendered across the top of the child form, so it looks as though there is one menu strip above the other. Basically, all the menus get moved from the MS2 into MS2, but MS2 still renders, just as an empty Menu Strip.

How can I prevent this behavior?

I would prefer if the menu strips merged as they do now, but when merged, the child forms menu strip was not drawn.

Is there a way to hide datagrid columns

I created a table with 4 column. ProductID is one of them but I don't want to show this column. I set the DataSource of a DataGrid to this TABLE. However, vb.net doesn't like it when I use
mygrid.Columns("ProductID").Visible

Is there a way to hide this column? Any comment would be much appreciated.

Just replace the string with index of column..

YourGrid.Columns(0).Visible = False

Hey all,

Newbie question here that probably has a simple solution that I can't seem to find, but I'm new to programming and am still playing around. Wink | ;)

What I'm trying to do, is create a program that will allow someone to enter data into a couple textboxes. What I want to happen is, to have a button that allows the user to "save" his/her entered data in these textboxes so that when they launch the program again, these changes are displayed until they are changed again. Can anyone give me some sample code that would accomplish this?

Any help or links to appropriate articles would be greatly appreciated.

Thanks!

Oh, forgot to mention that I'm using VB.Net 2003.

Re: About User Entered Data

Hi, you can do this using the registry. Well thats what I did.

To save the settings to the registry you need this code

My.Computer.Registry.CurrentUser.CreateSubKey("name of your program")<br />
<br />
My.Computer.Registry.SetValue_("HKEY_CURRENT_USER\name of your program","textbox name", textbox name.Text)

To load the data back into the textbox you can use this.

textbox name.Text = My.Computer.Registry.GetValue("HKEY_CURRENT_USER\program name", "textbox name", Nothing)

You need to put this code in a button or a timer and something like that.

Good luck Laugh | :laugh:

Just wanted to thank you again for the help. I got it to work properly, although using a slightly 'different' wording, i suppose. Your code was giving me some errors, so I looked for a couple of different ways of doing the same thing and this one ended up working for me.

My code ended up looking like this:

<br />
Dim CompSN_Reg As Microsoft.Win32.RegistryKey<br />
<br />
        CompSN_Reg = Microsoft.Win32.Registry.CurrentUser.CreateSubKey("ACQ01")<br />
        CompSN_Reg = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("ACQ01", True)<br />
        CompSN_Reg = Microsoft.Win32.Registry.CurrentUser.CreateSubKey("ACQ01\\CompSN")<br />
        CompSN_Reg.SetValue(txt_ACQ01_Comp_SN.Text, txt_ACQ01_Comp_SN.Text)<br />

Same idea in theory... but so fickle. Ahhh, I'm constantly reminded why I've always hated programming. Laugh | :laugh:

Anyways, Thanks! Smile | :)

Beside using the registry, you can use My.Settings to store your setting.

You have to create your setting in Design Time
You can set this in Project Properties and point to Settings Tab.
The settings will be save into XML format in your application path

here's the code to change and save the settings
----------------------------------------
My.Settings.UserName = "BrazenSix"
My.Settings.Subject = "About what??"
My.Settings.Save()

to retrieve settings value
----------------------------------------
Dim UName, USubject As String
UName = My.Settings.UserName
USubject = My.Settings.Subject

Creating Remote Desktop Application

Re: Creating Remote Desktop Application [modified]

26-Jul-06 6:12

I cant find any sample code for Remote Desktop in Visual Studio 2005. Does anyone have some sample code to connect to a terminal server or know where I can find some? I have played around with the "Microsoft RDP Client Control", but have not been able to get it work correctly. I would like to be able to connect, change the screen size, etc.

Windows authentication with login form

28-Jul-06 8:22

Have you typed in the IP address or host name in the server box in properties

You need to make the sure that the computer you are connecting to will accept RDP connections and the username you are going to use must have a password and be an administrator or have a password and be in the remote desktop group.

Wink | ;)

Re: Windows authentication with login form

26-Jul-06 5:58

I want to create a program that will prompt a user for a windows user name and password that authenticates against active directory. Once authenticated I want them to only be able to access particular forms based on their group permissions in active directory. For instance once logged in if they are in the Telnet group they can access the telnet portion of the program if not then they get a generic error telling them to contact their system administrator. They way I see it working is that when they log in it also checks to see what groups they are in and stores it as a variable. Each form that they then access checks that variable and if that group is not listed then the user will not have access to that portion of the program.

Thanks for any and all help.

If you're using VB.NET or VB2005. Please spend your time to look at MSDN Help:

From 'My' you can get a lot of information about security, Devices, etc..

Multiple forms+Icons

Automatically adding headers and footers in print documents

26-Jul-06 5:57

I am new to programming in Visual Basic .Net and I am looking to create my first real program. The program will contain a telnet and Ftp portion that I want users to be able to start by clicking on an icon on the main form. I then want that form to run in the main form and still allow the user to start the another form by minimizing the current form. If anyone has worked with Photoshop, I want to basically allow two or more forms to run at the same time (just like you can have to photo projects open at the same time) and allow them to be started by click an icon on the main form. The biggest problem I have is being able to create Icons that appear on a form similar to the picture shown below. I have various icons that I can use in .ico and .png format. I also need the forms to be able to be minimized and still appear on the main form so it can be maximized later if needed. Hopefully I have included all the information needed.

Thanks

Re: Automatically adding headers and footers in print documents

26-Jul-06 5:52

I would like to create a print function that will automatically put headers and footers on the document. This will be used to print out quotes to send to customers. The headers and footer will contain the company logo, address, etc, and needs to be in color. The body of the document will come from a text file that will be imported. I would like to also set a specific line that it should start at when it brings in the text file or prints it off. The way I see it working is that it uses Word objects to create the final document once all parts are put together.

How do I do it?

Bear in mind that if you use MS-Word to do this then your users will need to have MS-Word installed on their machine to print out.

Instead you could create the document template in code using the .NET PrintDocument class - I have written a couple of articles on this site that do that....
