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

how to link of two forms in vb

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.

here are my sample of codes i write a program that make an addition if checkbox checked or radio button checked i tried to show all of it with "toplam" but it gives the result 0 where i did something false any ideas???
Public Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
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
ElseIf RadioButton5.Checked Then
toplam &= Ayarlar.TextBox18.Text * baskisayi
ElseIf RadioButton6.Checked Then
toplam &= Ayarlar.TextBox17.Text * baskisayi
ElseIf RadioButton7.Checked Then
toplam &= Ayarlar.TextBox15.Text * baskisayi
ElseIf RadioButton8.Checked Then
toplam &= Ayarlar.TextBox19.Text * baskisayi
ElseIf RadioButton9.Checked Then
toplam &= Ayarlar.TextBox20.Text * baskisayi
ElseIf RadioButton10.Checked Then
toplam &= Ayarlar.TextBox21.Text * baskisayi
ElseIf RadioButton11.Checked Then
toplam &= Ayarlar.TextBox16.Text * baskisayi
ElseIf CheckBox1.Checked Then
toplam &= Ayarlar.iccizim.Text
ElseIf RadioButton12.Checked Then
toplam &= Ayarlar.rcilt.Text * forma
ElseIf RadioButton13.Checked Then
toplam &= Ayarlar.cilt.Text * forma
ElseIf CheckBox6.Checked Then

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.

Like I said, it seems possible that you're multiplying by zero. I also don't see any code that should show the result. I also am not sure if &= is what you want, this does a bitwise AND. At least, it does in C#. What does it do in VB ?
You should set a breakpoint and step through the code, to work out what is wrong.

no no it's not multiplying with zero i give a more number then 16

&= concatenates strings, doesn't it ? Have you stepped through the debugger to see what it is doing ?
VB totally sucks, your problem could be to do with the implicit conversions that are going on.

Briefly looking at the code, and as Christian has eluded to, there are a lot of potential problems that could be eliminated by making the code type safe. To do this include Option Strict as the first line of the code file. You can do this at a project level in the compilation options.
Once you have don this you'll have to cast all those TextBox.Text values to integers, for example:
forma = TextBox1.Text / 16
becomes:
forma = CInt(TextBox1.Text) / 16
Assuming forma is actually an integer.
Once you've done this, if something is wrong you should get a runtime error tring to cast the the text in you textboxes that will point you towards the next step of your debug process.
Hope this helps
Tom

forma is single and i could't look step by step in VB 2005.i didn't know how to do it and it gives no error

Put a break point in on the first line of code that you want to step through. To do this put the cursor on the line and press F9.
Then run the code. It will stop at that point, press F11 to step through each line of code and put your cursor over the variables to see what's in their values.
Cheers
Tom

to convert textbox text to single:
froma = cdec(textbox.text)
Note that if a non-numeric character (a letter or a symbol) is entered into the textbox it will cause an exception error, to get around that use a validation technique such as
if isnumeric(textbox.text) = false then<br />
messagebox.show("you did not enter a number!")<br />
textbox.focus()<br />
end if<br />
what this does is alerts the user to his/her error and forces them to correct it
now as for the step-by-step.
The step-by-step shows you what the complier is actually running, so if it never gets highlighted it never has been called
Example:
if true= true than<br />
'this code will always run<br />
else if x = 10 then<br />
'this code will never run<br />
else<br />
'this code will also never run<br />
end if<br />
Hopes this helps
