db.Contacts and 3 more classes are generated by sqlmetal, the solution would be to modify this classes to have properties just for database columns I need? (the primary key is in my "column-wish-list"). This probably would work but it seems to me way to complicated and across the program there are about 5 column combinations.
Thanks

I want to set the file of types in Open File Dialoge to a specific type such as ".bmp"
|
|
|
|
|
Why don't you read the documentation? OpenFileDialog has a property called filter which allows you to set file type.
|
|
|
|
|
could u please give me an example on how to use it !
|
|
|
|
|
As I already said in my first reply, why don't you read docs? Or google? Or search here, on codeproject? No one is going to do it instead of you. Learn googling.

Through code behind with the save button. You'll have to code it yourself since no one knows what your database looks like.

Use ItemTemplate Field and use Combox in It!! your problem will solve
Steps
a)add a column to the gridview which is a TemplateField
b)Edit the templateField and drag ComboBox into the template!

Hi sindhutiwari,
1) First retrive the data from database to DataTable.
DataTable objDataTable = new DataTable();
objDataTable.Columns.Add("DataColumn1");
objDataTable.Columns.Add("DataColumn2");
dr = objDataTable.NewRow();
dr[0] = "data1";
dr[1] = "yes"
objDataTable.Rows.Add(dr);
2) Now you can bind this datatable to datagridview. You should set the "DataPropertyName" property of datagridview column.
grdView.DataSource = objDataTable;
this.grdColumn1.DataPropertyName = "DataColumn1";
this.grdColumn2.DataPropertyName = "DataColumn2"; // grdColumn2 is comboboxcell it contains 2 items (yes/no). other values not accepted.

I am developing a simple phone book application and i need to save the contact photo when adding new contact
and retrive it again when searching for them later.
|
|
|
|
|
This is very simple to do. just upload image corrosponding to the contact person and disply it from database.
you can store image in database as binary format
or
you can store image in a folder and store the path with data base corosponding image
e,g:
ID Name Address ContactNo Image_Path
------------------------------------------------------
1 MyName MyAddress 123456789 d:\AppFolder\MyName.jpg
2 UrName UrAddress 987654321 d:\AppFolder\UrName.jpg
Just Do in this way !!
While retrive with id, or name use image box to show the image
Any more query ??? Always welcome !!!

hi
my code is not working .can any one suggest me.
private void Form1_KeyPress(object sender, KeyPressEventArgs e)<br />
{<br />
if(e.KeyChar==(char)27)<br />
{<br />
this.Hide();<br />
}<br />
}

You are hiding your form, not closing. If you want to close your form use this.Close()
Also, if you have controls on the form, make sure that your form is processing key press until they reach the controls
