how can i call this function in my button click event?
i never use this method before, after google it i just find call function
from other developer software like javascript, c and c#
plz help me..

How do you call other functions at the moment?

I encountered a project a few years back written by some indian guys in vb (they "apparently" had some c# background). everything was written as a function, no "subs" anywhere whatsoever.. All these functions returned nothing.. Their idea of code reuse was to bung everything into one huge global class and define it in every single page they wrote, even if no functions were used from that class (this was their idea of code reuse) . It was a joke.
On thinking back, this entire project qualifies as a coding horror!

since your function(as you specified in sample code) return image so suppose your button name is "Save". so on click event of this button use following code
Private Sub cmdSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSave.Click<br />
dim ob as image<br />
ob=merge(byval anyVaribale as object)' you can put anything in place of object datatype<br />
<br />
End Sub
hope this helps

My app displays the following two error messages. I have an unhandled exception sub to catch these, but its displayed anyways. When run locally (both as build or debug), I see no error messages. Am I missing some sort of .Net configuration?
1st[^]
This is a result of running:
Try
Dim HowManyCities As Integer = SQLCount("SELECT Count(LCF_Info_Market) FROM " + cboMarket.SelectedItem.ToString, Database)
Dim Cities(HowManyCities - 1, 1) As String
Dim i As Integer
Cities = GetCities("SELECT LCF_Info_Market, LCF_Info_Code FROM " + cboMarket.SelectedItem.ToString, Database, HowManyCities)
For i = 0 To Cities.GetUpperBound(0)
cboCities.Items.Add(Cities(i, 0))
Next
PopulateCodes()
Catch e As Exception
MsgBox(e.ToString)
End Try
2nd[^]
This error is simply from:
Application.Exit()
|
|
|
|
|
I need to be able to validate the list View. I need to know how to check and see if the user did not check a box.
|
|
|
|
|
Just have a boolean value set to true or false based on if a box has been checked. Set the boolean value in an event procedure that is fired when the box is checked. That is my quick stab at it, without any detailed code or description of what you are trying to do.

This is my validation if statement. When I debug I get an error. Can you give me an example of how to check for a checked item using the boolean value?
If lvwRent.CheckedItems(0).Text Is "" Then
|
|
|
|
|
why would you need Text? just look at the count of the items in lvwRent.CheckedItems

Thanks, Luc, you saved me from some code typing

When code does not feel good, I'd prefer to remove some, rather than add some.

i hav window service app. when i start the method call by onstart method fire only once
|
|
|
|
|
The OnStart[^] method only fires once, so any calls in it will also only be fired once. Start a thread in OnStart if you want something to loop. (Don't do a loop in OnStart as the service won't finish starting until the loop completes.)

i did not do a loop . already have a loop please look at the code

My guess is the System.Threading.Timer is not keeping the service running, as opposed to a thread[^] which will keep the service running.
The last time I made a service, I created a thread in the OnStart event and I put the code for what I wanted the service to do in the thread. The service would keep running until that thread was terminated.
Someone else feel free to correct me if I am wrong.

I'm in need of a quick answer to a problem. I am trying to parse a tab delimited file for the purpose of feed it to a check printer. I am using a stream reader and the issue is that the reader is dropping the first char of each line. Here's the code:
Do While strRead.Read <> strRead.EndOfStream
strTest = strRead.ReadLine
strWrite = strTest.Replace("""", "")
ListBox1.Items.Add(strWrite)
Loop
Can anybody help?
Thanks

ok I found a solution this method from the MSDN worked. I'm not sure why at this point. When I figure it out I'll let you know.
Using sr As StreamReader = New StreamReader("TestFile.txt")
Dim line As String
Do
line = sr.ReadLine()
Console.WriteLine(Line)
Loop Until line Is Nothing
sr.Close()
End Using

Hi,
I would guess strRead.Read really reads something, maybe one byte or so, and you
don't process it. Did you care looking at the documentation of the classes you use?
|
|
|
|

Come on now read documentation? Who does that? No your right under the pressure of an angry ap clerk I did not research class well. Since I have been doing this since vb3 you'd think I'd know beter by now.

Real people.

Well, let's see the angry ap clerk do a better job, which I doubt

He obviously didn't and can't believe the attitude he gave you in his reply about reading documentation.

Did you get that he was poking fun at himself in his reply?
Did you see the "Red face" emoticon?
He wasn't giving any attitude. He was saying "Doh!".

Looking back at it, yes.

strRead.Read reads the first character of every line.
do while not str.Read.EndOfStream
...
loop
