Hi Melanie,
is the sqlquery-text correct (I mean are the values you are using correct).
Next question I have i, why aren't you using the db1Reader like this:
<br />
while(db1Reader.Read()) {<br />
<br />
}<br />
I don't see the point where you putting the Values from the db1Reader into the db1table. So I assume that db1table has no rows...
Hope this helps.
Regards
Sebastian

Aside from the other post, you really need to not build SQL queries like that. You're very prone to someone injecting something that would compromise the system.
Do some searches on articles here at CodeProject regarding SQL Injection to find some tips on how to resolve the above issues.

You can use controls in a loop using FindControl(string name) (self made method).
However i would like do a loop with objects like:
string str1 = "test"
string str2 = "test"
string str3 = "test"
for (int i = 0; i < 5; i++)
{
str[i].Text = "test2";
}
Also tryed:
string new = (string)str[i];
Also didn't work.
Any idea/methods for doing something like this?
Thanks

No, you can't create a few objects named like this and then try and iterate through them like they are in an array.
Either add them to a collection, and iterate through that:
String str1 = "test";
String str2 = "test";
String str3 = "test";
List<string> strings1 = new List<string>();
strings1.Add(str1);
strings1.Add(str2);
strings1.Add(str3);
for (int i = 0; i < 3; i++)
{
strings1[i] = "test2";
}</string></string> Or create an array of them to begin with:
String[] strings2 = new String[3];
strings2[0] = "test";
strings2[1] = "test";
strings2[2] = "test";
for (int i = 0; i < 3; i++)
{
strings2[i] = "test2";
}

Hi
Thanx for that link but it uses file to store and retrieve.Is it same for database retrieval.And also i want that image to display in some specific area of my page .
|

It stores data in database. In order to show it on form you can use Image.FromStream method to construct the image after you read data from database in stream.

HID devices uses in and out -put reports.
Not really an answer but i hope it helps you a little further.

hi,
how to add control like button from one Form to another Form at runtime?
i have tried this one :
Form2 objForm2 = new Form2();<br />
objForm2.Controls.Add(this.button3);
i think button3 add on Form2 with successfully but.......new added control "button3" not shown on Form2 why?

A GUI control can't appear on two forms at the same time.
Just like you can't have the same button appear twice on one form. A GUI control has only 1 visual representation at a time. If you want two buttons you need to create 2 buttons, not try and use the same button twice.
(You can create 2 buttons and attach them both to the same event handlers if you want them to call the same code)

i used following code:
frmTimetablePopup objfrmTimetablePopup = (frmTimetablePopup)Application.OpenForms["frmTimetablePopup"];<br />
DataGridView grd = new DataGridView();<br />
grd.Name = "grd";<br />
grd.Location = new Point(310, 300);<br />
grd.Size = new System.Drawing.Size(600, 600);<br />
DataGridViewTextBoxColumn grdCol = new DataGridViewTextBoxColumn();<br />
grdCol.HeaderText = "Days";<br />
grdCol.Name = "Col1";<br />
grdCol.Width = 50;<br />
grdCol.DefaultCellStyle.BackColor = Color.CornflowerBlue;<br />
grd.Columns.Add(grdCol);<br />
objfrmTimetablePopup.Controls.Add(grd);
but fail ........

You're code works fine for me. You're setting the location to 310,300. Is this off the edge of your form.
grd.Location = new Point(310, 300); Try setting it to 0,0 instead.

Well the code is fine and it works fine for me, so it is something you are doing wrong somewhere else.

I just gave you a suggestion:
I wrote:

Have you tried that?
Did it work?
What happened?

Ok, what I assume you want to do then is create a word document dynamically and allow the user to download it. You will still probably need to use VSTO to create the word document. You will need to have word installed on the server (which by the way I don't think is supported by MS).
Why do you want to make it available as a word document? This ties your users to MS. What if one of your users doesn't have word? You would probably be better going for a more universal document format like PDF. There are plenty of commercial and free PDF libraries available for .net
You need to ask in the asp.net forum for how to go about doing making the created document available for download.
