So, you need to write queries that only return the records you want to show on each tab. That's just some basic SQL filtering you need to do.

OK, well, it's pretty straightforward. Did your query return anything ? Did you bind the data to the grid.
detective_girl wrote: actually now i don't know what kind of queries to write
Well, I don't know what to say - your comments are all so vague. Do you mean you don't know any SQL ?
detective_girl wrote: where to write them in tabcontrol or in tab of each page
Your data layer should be seperate to your presentation layer. Then, as each tab is selected, it would have a datagrid which calls the appropriate method in the data layer.
The first step is to write and test the SQL. The second is to put methods in your data layer to call the different data base methods. The third is simply to bind the grid to the right method, according to the selected tab.

Hi could anyone please tell me how to get the size of an image on the internet, without downloading it first.
Basically I want to check if it's a certain size before I download it. At the moment I am getting the image links of a web page via the Webbrowser control and then loading each image into a picturebox control, set to autosize. If the image is a certain size , I will then save the picturebox contents to file. This is very slow though as I am downloading lots of images that aren't big enough just to check their size.
I Have seen a program called 'Get File Size' http://www.unhsolutions.net/GFS/downloads.shtml that can do this very quickly.
Thanks in advance,
Darren.

You can't. There's nothing in the HTTP specification for retrieving file size. You'll have to start the file download, look at the headers of the response from the server to get the size, then cancel the download.

Thanks for that. Is that how the program 'Get File Size' would do it. They get the size back in about a quarter to half a second? Would the response come back that fast?
|
|
|
|
|
That depends on the response time of the HTTP Server, but yes, it can.
That's the only way I know of to do it.

Sorry to be a pain, but I'm just confused myself. How do I look at the headers when then response coming back is just for a jpg file in the webbrowser. I've just been trying it and I cant seen to get the file size without still loading the image?
Thanks again.

You can't use the WebBrowser control for this. You have to create your own using the HttpWebRequest class to make the request. You'll get back a WebResponse object that has a Headers collection property that you can examine, or you can look at its ContentLength property.

OK, mouse is clear, and combox probably stands for combobox, hence the answer is: yes, you can select combobox items with the mouse.

Dear All,
does anybody know how to set the decimal point in smart device ?
I write code like the following lines:
Imports System.Globalization
Imports System.Threading
Public Class frmDecimalTest
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim ci As New CultureInfo("it-IT")
Dim nfi As New NumberFormatInfo
nfi.CurrencyDecimalSeparator = ","
nfi.CurrencyGroupSeparator = "."
ci.NumberFormat = nfi
'Thread.CurrentThread.CurrentCulture = ci
End Sub
End Class
I don't know how to set the current culture (in smart device application, there is no Thread.CurrentThread.CurrentCulture event. Thanks a lot for helping

Your header is the name of the forum, and your question would have made a good header. What do you mean by 'link' ? Do you mean pass information between them ? You can put properties on a child form and access them from the main form, but delegates are the best way to communicate between forms.

forma = TextBox1.Text / 16
End Sub
Dim baskisayi As Single
Public Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged
baskisayi = TextBox2.Text / 500
Call isaretliyi_bul()
End Sub
Private Sub isaretliyi_bul()
If RadioButton1.Checked Then
toplam &= Ayarlar.TextBox1.Text * forma
ElseIf RadioButton2.Checked Then
toplam &= Ayarlar.TextBox2.Text * forma
ElseIf RadioButton3.Checked Then
toplam &= Ayarlar.TextBox3.Text * forma
ElseIf RadioButton4.Checked Then
toplam &= Ayarlar.TextBox4.Text * forma

I have no idea what you're asking, but this code is incredibly nasty.
Use a switch instead of all these elseifs, assuming there's no other way. And, for goodness sakes, give your checkbox variables meaningful names. If the code for checkbox9 and checkbox8 are the wrong way around here, how would you tell ?
alpdoruk wrote: forma = TextBox1.Text / 16
If TextBox1 ( there are those variables again ) has a value < 16, the return value will be 0. and so, the result will be 0.
alpdoruk wrote: Ayarlar.TextBox1.Text * forma
It looks to me like you have a form with public variables ( textboxes ). Don't do that. Expose the strings only if you need to.
