what you have tried so far? it's not that difficult as you think.

I'll give you another hint; you could replace[^] an old value with a new value.

Hi, how can i make these two functions in my form (Zoom in or Zoom Out)?
i wish to increase or decrease size in my form
|
|
|
|
|
You'll have to be a bit more specific than that. What exactly do you want to "Zoom In/Zoom Out"?? A picture being displayed? The contents of the entire form, including all of it's controls?? What?
|
|
|
|
|
without knowing what you are trying to zoom in or zoom out from I would start having a look at the ScaleF methods
System.Windows.Forms.Control.Scale[^]

Hello Commmunity,
I am very new to VB and would like some help with a small project. I am trying to modify a column in a csv file and save my changes to a new csv file. Here is a sample of my file:
firstname, lastname, phone, email
john, smith, 1111111111, jsmith@someone.com
brad, green, 2222222222, bgreen@someone.com
I would like to search for value 'phone' in the column and replace it with 'cell phone' or change any existing column name with a new value.
firstname, lastname, cell phone, email
john, smith, 1111111111, jsmith@someone.com
brad, green, 2222222222, bgreen@someone.com
I found a few examples to import the csv into a datatable but I have not found a solution that would allow for an empty value from the orginal csv file into VB datatable. Here is an example:
Import File:
firstname, lastname, phone, email
john, smith, 1111111111, jsmith@someone.com
brad, green, 2222222222, bgreen@someone.com
sam, brown, 3333333333, ,
mike, black, , mblack@somesone.com
Export File should be this:
firstname, lastname, cell phone, email
john, smith, 1111111111, jsmith@someone.com
brad, green, 2222222222, bgreen@someone.com
sam, brown, 3333333333, ,
mike, black, , mblack@somesone.com
Thank you,
Mike

It'd be faster to do this using Notepad++, since the column-title is only present on the first line of the CSV-file. That's also the easiest way to build your project; read the content of the file, replace the word, write it. Take a look at the classes in System.IO.

If your purpose is to replace all data placed in a certain column (for example, the "phone number" field), you can do it programmatically.
The following function can be useful for that purpose:
' This function returns a token based on its place.
Public Function GetToken(new_txt As String, delimiter As String) As String
Static txt As String
Dim pos As Integer
' Save new text.
If new_txt <> "" Then txt = new_txt
pos = InStr(txt, delimiter)
If pos < 1 Then pos = Len(txt) + 1
GetToken = Left$(txt, pos - 1)
pos = Len(txt) - pos + 1 - Len(delimiter)
If pos < 1 Then
txt = ""
Else
txt = Right$(txt, pos)
End If
End Function

Hi, Please help me in checking the condition.I am displaying information in a html table.

If I select same status then it shouldn't through an error message.
I have code like below. Here rs means the number of records in the second grid.
If rs.RecordCount > 0 Then

Dear Expert,
I have a Listview with subitem which i add populate data in listview which is lengthy, i want to shorten the code, i tried For loop but it give me error at run time. With Do loop it working.
Do Until rs.EOF = True
Set LI = ListView1.ListItems.Add(, , rs(0))
LI.SubItems(1) = rs(1)
LI.SubItems(2) = rs(2)
LI.SubItems(3) = rs(3)
LI.SubItems(4) = rs(4)
LI.SubItems(5) = rs(5)
LI.SubItems(6) = rs(6)
LI.SubItems(7) = rs(7)
LI.SubItems(8) = rs(8)
LI.SubItems(9) = rs(9)
LI.SubItems(10) = rs(10)
LI.SubItems(11) = rs(11)
LI.SubItems(12) = rs(12)
LI.SubItems(13) = rs(13)
LI.SubItems(14) = rs(14)
LI.SubItems(15) = rs(15)
LI.SubItems(16) = rs(16)
rs.MoveNext
Loop
|
|
|
|
|
LI.SubItems(i) = rs(x)
What is the value of i in this statement?
|
|
|
|
|
Dear Sir,
is this the right path to display listview subitems with for loop
Li.SubItems(x) = rs(x)
|
|
|
|
|
What happens when you try it?
|
|
|
|
|
Dear Sir,
It work. But i just want to know it will affect the other program when compile or not.

In what way affect other program? All you are doing is adding items into a list.

Can you help me for the vbcode for the game grow island or grow valley ? Thanks !
|
|
|
|
|
Nope.
VB6 is dead and, from what I can find, Grow Island is a Flash game, not VB6. if you want to write it yourself, go right ahead. We're not going to do it for you.

i was looking for the code of upgrading or evolving an object to another or maybe animation for it what code can i use ?
|
|
|
|
|
That code is custom written for you game objects and environment noone is going to write it for you and you really haven't defined what you mean by an "evolving object".
Seriously, drop VB6 and use something more modern, like XNA studio, C#, C/C++, and pick up a bunch of books on game programming.
Oh! You'll find that NONE of them use VB6.

We have 2 VB.Net 2008 programs.
They are not 'related'.
They are in separate folders.
If I change a module in 1 via VisStudio and save it, then the other gets
This File has been modified outside the source editor.
The module is NOT in the Solutions Explorer of the 'victum' program.
It happens on more than 1 module and both ways but it does not seem to be for all modules.
How can I stop this form happening???
