Dear,
I start programming a very small project called "CD Collection" for my self learning which is using C Sharp 2005 and MS Access 2007. I would love you to instruct me if possible. I can insert into table (eg: tbl_user (uID, username)) normally but I've no idea how to load these data to combobox (in other form - tbl_cd (cd_id, music_code, uID, cd_set_id)). So, what do I've to code?
1. How to load data from db to combobox?
2. After successfully loaded, I want to know how do I insert uID(from combobox) back to uID in tbl_cd?
Many thanks,

If you set the datasource of the combobox to be the dataset you get back from the DB, you set the displaymember property to set which column the combobox should show.

I have written a C# class which I wish to use in other projects. I have not been able to sift thru the MSDN or code sites to find an example of what I need to add to my code to enable it to be registered and added to a .net project as a reference. This class will be used by other programmers in there project and I do not wish to provide the source, I would rather provide a DLL for them to use.
Can anyone give me some guidance?

just set in project properties "Application type : DLL", just compile it, and you can use it from another application as a reference. It is so easy.

stancrm,
I am using C# VS 2005 and it does not have the DLL option for Application (Output) Type, only 'Windows Application', Console Application', and 'Class Library' - which is what I have selected believeing that a DLL is a Class Library. After compiling for release, I get a "Failed to find 'DLLRegisterServer' function" in DLL error message when I try to register with 'Regsvr32'.
I do Thank You for your assistance!!!

Hi,
yes, class library results in a DLL, however a managed code DLL does not need registering, and can't be registered with regsvr32; you can use it in another project by adding a reference to it (solution pane, right click project, add reference...)

Okay, Vista seems a big mess when using TransparencyKey...If I set BackgroundColor of a form to Red as well as TK to Red then I can't click through the form(invisible area). But if I set BackgroundColor and TK to Magenta or Lime then I can click through...wow but thats just not enough. If BC and TK of form is Red and I drag a Label set its BC to Blue and Text to empty then Label will appear with Blue color but if I click on it then the window behind it in z-order will get activated however if I click the invisible part of form that then it doesn't a click through. Whats that ? any idea ? 'coz everything working fine in XP SP3

Hi
I have created a graphically heavy windows forms application and when I minimize this application to system tray and bring it back, the form flickers for two seconds. Form contains over 5 transparent PNG images.
I am using this code to minimize to tray:
this.WindowState = FormWindowState.Minimized;
this.ShowInTaskbar = false;
TrayIcon.Visible = true;
TrayIcon.ShowBalloonTip(2500, "GameSec hala çalışıyor!", "GameSec hala çalışmaktadır, tekrar görünür hale getirmek için tıklayın.", ToolTipIcon.Info);
and this code to show it back:
this.WindowState = FormWindowState.Normal;
this.ShowInTaskbar = true;
TrayIcon.Visible = false;
I am aware that Hide() and Show() can be used in normal situations but it doesnt work for me because this form I am talking about is owned by another form.
Here is a video that I've created for you to see the problem by yourself:

Thanks in advance.

This article Flicker free drawing using GDI+ and C#[^] has some hints.
Also if you are drawing on to panels, you can sub-class the standard panel, and just add the following to the constructor.
SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.OptimizedDoubleBuffer, true);

I think thats normal 'coz GDI+ is slow. BTW did you notice something, when the form was flickring a magenta type color shown, I think you should change that color to gray or something similar to that form.

As Blue_boy has said. Post your code. Show us what you have tried so far.
If you do not wish to do that, then I would suggest that you search the MSDN Documentation, where you will find loads of examples.

The message and title of the MessageBox use the system font,right?when i sent unicode string to the MessageBox,the message and title didn't appear normally.I am writing unicode based code,the string is unicode based(Uyghur language). This is the same on the title message of the Form,uyghur text is shown normally in the other controls. Is there any way to solve this problem? I know i can replace the system font with other fonts by modifying the desktop property. Is there any control that fix this,like RxLib(supports Delphi),or is there anything can set the MessageBox font?any help will be appreciated,thanks!!

how to make server which 10 000 clients and more?
|

I presume you wanted a server app that can hold 10 000 Connections?
The app is not main issue, you need a fast server with enough memory. App is same as it would hold 2 or more connection
