Hi,
we can set a datatable to datasource.if u want to fill those numbers to combobox we need to loop & then fill datatable & then assign it to combobox.datasource property. Better to use "combobox1.items.add " & a loop .
Display member property is used when we have more no.of columns in a query
for ex: -
<b> SqlCommand cmm = new SqlCommand();
cmm.CommandText = "select Emp_Id,Emp_Name,Emp_Address from Employee";
cmm.CommandType = CommandType.Text;
cn.open();
cmm.Connection = cn;
DataTable dt = new DataTable();
SqlDataAdapter sqldt = new SqlDataAdapter(cmm);
sqldt.Fill(dt);
comboBox1.DataSource = dt;
comboBox1.DisplayMember = "Emp_Name";
comboBox1.ValueMember = "Emp_Id";
cn.close();</b>
While Displaying it Displays employees Name & if u are going to save it in table then we can use
"comboBox1.selectedvalue" property were we get the Emp_Id

i don understand what u mean "min value & max value" ? however i think that in my combo box just store some string values n id. and i want to ask u a bit more... does combo box can store more then 2 colume or fields. for eg: Emp_ID, Emp_Name, Emp_Gender,Emp_Phone.. ?

No Combo Box can store only 2 columns by 2 Properties
1.DisplayMember - This does the work a displaying a column
2.ValueMember - This does a work what value should be returned when a particular item is choose d.
Ex:-
EmpID EMP_Name
1 abc
2 def
3 xyz
when u select a Emp_name - "def" from combo box & if u use "combobox1.selectedvalue" then it returns 2 or if u select "xyz " then it returns 3
doesn't mind if u still didn't get it.Just reply for doubts.

Form has BackGroundColor and BackGroundImage property. Use it.

?? I don't know what you want, but if you want to change background color of a form, just do like this:
MyForm myForm = new MyForm(); // Here is your form
myForm.BackColor = System.Drawing.Color.Red; // Change the background color to red.
|

|
|
No No, i want to set a image file
|
|
|
|
|
Use BackGroundImage Property of ur form!(Singl-Click on ur form, then press F4. and use BackGroundImage Property to set an image.

The BackgroundImage property has been a part of every control since .NET 1.0, so I am sure it exists in yours! Are you sure you have a form, not a console application? Can you open the designer view on it? If so, then check the properties are listed A-Z and that you aren't viewing the events. If really desparate, try using intellisense and check it programatically:
frmMine fm = new frmMine();
fm.BackgroundImage = @"C:\Pic.jpg";
If this comes up with errors, then paste your code here, with the error message.

For Setting the background image of your form
YourFormNAme.BackGroundImage = YOUR-Application-NameSpace.Properties.Resources.YOUR-Resource-Name;

Hi All,
I am using Visual Studio 2005, .Net 2.0. In my application, i am using more number of Designer Host instances, So when i am using more than 36 instances of Designer Host, i cant able to resize the controls. If the number of instances of Designer Host is less than equal to 36 , then it is working fine.
Below is the link of an example given by the microsoft. It is also giving the same problem when adding more than 36 forms(i.e. Designer Host Form).

Can anyone please give me a solution.
Thanks & Regards,

We are working on a .net application that would require to update the inventory tables of Peoplesoft database. What is the best way to do this, i.e, to update the inventory tables of Peoplesoft by an external application?

You asked it twice yesterday and you've started asking it again today. The question is, what does it have to do with C#?! Even though your application is on .NET, your query has something to do with some third party stuff.
You will need to read the Peoplesoft API manual and/or go and ask it in one of their forums. There is no point in reposting this stuff every day here.

Dear Friends,

Sounds trivial to me. What have you done so far ?
