The answer to that is self evident, the DAL either takes instances of entity classes that contain the data needed, or parameters that contain the data required. Just like any other function you'd write, in any program.

Hi

I've been trying to create a custom textbox control using Visual studio 2005(VB.Net) with the properties that a normal texbox have with additional appearance and functionality that looks like this |_|_|_|_|_|_|_|_|_|_|_|_|.

If I need to use it for title it will be something like this |_|_|_|_|

For an address |_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
etc.

The has to be only one entry in each box and be able to set a colour for the lines and this lines must touch the textbox borders and not live spaces between like on this message.

I've been using the Web Costom control in the Web Control Library to do this and read GDI+, but something is just missing,

Can anyone please help me out with this I need it for my peoject.

Thanks

You can't use graphics with a web control. A web control is rendered as html code, so that is what you are limited to.

He answered you. For a web page, you can't.

Can you do it in a Windows Application then

Yes. You just override the Paint method. That will be called whenever the control is drawn, so you call the base implementation of the method to do the original drawing, then you can draw whatever you like on the control. The event arguments sent to the method contains a graphics object that you should use for doing the drawing.

Guffa is right, but the caveat is that the underlying text control in windows draws itself outside of the paint event often, so doing a custom text control, while possible, is a real PITA.

I have two forms in vb.net2003. first form is welcome screen & 2nd form is login form. I must hide the welcome screen. then the login form must be appear. my login form's back ground is in transparent. when load my login form,the welcome screenform is hide but that is appear behind the login form. when load my login form, the welcome screen form might not appear.
How can i solve this problem?

Christian Graus30-Sep-07 22:45

30-Sep-07 22:45

I can't follow this. The login form is covering the welcome form ? Don't show it until the welcome is closed, or make the welcome screen topmost.

don't know if this is what you want but you can put you'r welcome screen as splash screen
in the properties of you'r project
then the welcome screen will appear as first screen for a few seconds and after that the project will start

If my help was helpfull let me know, if not let me know why.

There's no such thing in VS.NET 2003. That stuff only showed up in 2005.

I keep getting the message that the file MSADDNDR.dll could not be registered each time I try to reinstall VB6.0 on my computer. What can I do to overcome the problem?

Hi
I need to build a web application with log-in controls (txtUsername, txtPassword, btnSubmit).
My problem is, if i click submit, it should automatically log me in to another site (a web mail) with pop-up authentication (just like the pop-up box when using basic authentication)

So basically, what i'm trying to do is i'm logging in to that page using my own page. The pop-up should not be shown anymore since i have my custom log-in controls.

Is it possible to get the control names/id of the pop-up box, pass the values from my page to these controls and execute click commands externally?

What if the web mail i'm trying to access doesn't have a pop-up authentication just like yahoo mail?
I found an article that this one is possible using the WebBrowser control but it seemed that this control is only available in windows applications.

Please help i'm new to .Net. I would appreciate it so much.

Thanks
berd

If you're talking about the credentials box put up by the browser, no. That pop up box is no part of the web page. There's no way for your ASP.NET (which runs solely on the web server!) code to put anything in the browsers login box on the client side.

True. The web browser control doesn't exist in ASP.NET apps, for obvious reasons.

Web Forms (ASP.NET) apps run their code entirely on the server, NOT on the client. Your ASP.NET code cannot establish a login session for another web site that doesn't run on your server.

I'm writing a .NET version of Panorama (it changes your backgrounds in win98 but has Issues on XP/Vista -- i dont maintain it... i just like it)
I have to handle It as a single instance application because i call the "ChangeDesktopBackground" command in user32.dll alot -- anywhere from 6 SECONDS to 4 HOURS... and i dont want a user going crazy because the desktop just changed 3935974958607367 times... it takes some doing too...

I was considering DDE, but its dead. OLE automation is near imposible without killing the filesize (its 200kb right now -- and only takes up 400kb in memory.)

I would like to have a command line param, say -a, that adds files to a listbox.

Heres how i have it set up:
FormMain
FormMain.Desks(ListView)
FormMain.AddSingle(Button)
FormMain.AddDirectory(button)
FormMain.RemoveItem(button)
formMain.clearAllItems(button)
FormMain.Timeout(spinCtl)
FormMain.TimoutTimer(Timer)
FormMain......

I want to be able to have it set up so that when the user calls something like
"PanoNet.exe -a C:\Epic Files\Some File.jpg" "C:\Mpre FIles\Some Other FIle.BMP" the new instance tells the old instance to add the two files to the top of the end of FormMain.Desks.Items

Can this be done?

"Pinky, are you thinking what i'm thinking?"
"I Dunno brain, who really came up with the idea for cheeze sticks?"
"... apparently not ..."

Dave Kreskowiak1-Oct-07 3:58

Yeah, it can be done. Just search the articles for "single instance" and you'll find a few that describe passing data back to the original instance of the app.

You may want to check into .NET Remoting (older) or WCF (newer) if using the .NET Framework 3.0. Basically, your app is exposing a server that a new instance of the app connects to as a client.

Updating database

Mr Oizo30-Sep-07 5:23

30-Sep-07 5:23

Hi. I have 2 tables named 24HourTemplate (with a primary key 24HourTemplateName) and a table called GenreTemplate(with a primary key TemplateName) joined to a composite table named 24HourGenreTemplate(both the Field 24HourTemplateName and TemplateName are primary keys for this table) The problem is when I update the Composite table it gives an error Message saying that Template name is constrained to being unique. It doesn't update obviously then. it is correct for the TemplateName and 24HourTemplateName fields to be unique but that is only for the tables 24HourTemplate and GenreTemplate. There will be duplicate values in the composite table. What am i doing wrong? I'm using an access 2002 database in vb.net2005. (each 24 hour template will have 24 genre templates applied to it)

- Do you mean a composite primary key comprising of 24HourTemplateName,TemplateName.

Mr Oizo wrote:

Sounds to me like you need to understand database design, as a primary key is unique i.e. you cannot have a non unique primary key.
It could be a foreign key as it joins to 24HourTemplate and GenreTemplate.

You always pass failure on the way to success.

Hi yes it must be a composite primary key. sorry. It holds the primary keys from 2 tables:"GenreTemplate" and "24HourTemplate". This "composite table" named "24HourGenreTemplate" has only the 2 primary keys from the other tables(set as the primary key) and another field called "time". I have other tables with the same structure and relationhips as this that do updat fine. this just doesn't want to? do i need to create a different primary key for the composite table?

Mr Oizo

GuyThiebaut30-Sep-07 10:55

GuyThiebaut

30-Sep-07 10:55

Ok I understand now - what I would ask is are you absolutely sure that the primary keys you are creating in 24HourGenreTemplate are unique?

Output the rows, via debug.writeline, inserted into 24HourGenreTemplate to double check that the two fields that make up the primary key only appear once.

for instance:
if the primary key is comprised of field1,field2

field1 field2 field3 
dog    big    alsatian 
cat    small  persian
dog    small  border
dog    big    bloodhound

The rules set up for a primary key are broken as the 1st and 4th row have identical keys.

Does this help?
