This involves proper use of each controls Anchor and Dock properties. Also, you may have to put groups of controls in various layout panels such as the Panel control, TableLayoutPanel, FlowLayoutPanel, GroupBox, SplitContainer, ... What and how you do this depends entirely on what your control layout is and how you want it to behave.
Start by creating a new project and dropping a couple of contorls on a form, playing the the Anchor and Dock properties of those controls, then resizing the parent window to see how they behave. Then add a TableLayoutPanel and start playing around with that, dropping controls into the panel.
Noone is going to be able to tell you step-by-step how to do this. You simply have to experiment with the stuff to learn how it works, then make your own decisions on how to layout your form based on what you've learned.

Thanks for your suggestion Dave... I will the same...
I was wondering if there is any com component or something like that available they way it was there for VB 6
|
|
|
|
|
No there isn't. Besides, how would it read your mind as to how you wanted the controls to work?

I have two forms, and what I want is to save the data in both forms to an excel spreadsheet. I want the information in form 1 to appear first, and the information in form 2 to appear after form 1.
e.g. this is the form:
I want the excel spreadsheet to appear like this:
and I want the information on the second form, form 2 to appear on cells J, K, L, M etc... after the first form 1 information.
I have a button that says "Save to spreadsheet" on form 2 and I want to save a spreadsheet with the information in the rext boxes on form 1 and 2 like I showed. Any ideas? I am using VB 2005
In the end we're all just the same

I have a text box on my form called "txtIntrest" and I want it to display the first line in a text file called "Intrest.txt". I also want that, if you change the text in the "txtIntrest", it will ask you for a password and you have to type one in and this changes the information in the text file. If you press cancel on the password screen, it reverts back to what was in text box originally.
Any ideas?
In the end we're all just the same

Hello Dave,
You can try using the following code implementation. In this I have taken a textbox and a button.
On form load, textbox automatically fills with the first line of the file. On button click, it
will check the text box for any changes and then it will do what you require. It will ask for
password and after verifying the password, make the changes back to the file. password is coded
right now. You can use various techniques to read it from a file.
BEGIN CODE
Imports System.IO
Public Class Form1
Dim myline As String
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim sr As New StreamReader("c:\test.txt", False)
myline = sr.ReadLine
TextBox1.Text = myline
sr.Close()
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim tempstring As String
Dim result As DialogResult
If Not TextBox1.Text.Equals(myline) Then
result = MsgBox("Do you want to save changes", MsgBoxStyle.YesNo, "Save")
If result = Windows.Forms.DialogResult.Yes Then
Dim pass As String = InputBox("Enter the Password", "Admin", "")
If pass = "Password" Then
Dim sr As New StreamReader("c:\test.txt")
Dim sw As New StreamWriter("c:\Temp.txt")
While Not sr.EndOfStream
tempstring = sr.ReadLine()
If Not tempstring.Equals(myline) Then
sw.WriteLine(tempstring)
Else
sw.WriteLine(TextBox1.Text)
End If
End While
sw.Close()
sr.Close()
File.Delete("c:\test.txt")
Rename("c:\temp.txt", "c:\test.txt")
Else
MsgBox("Wrong Password")
Exit Sub
End If
End If
End If
End Sub
End Class
END CODE
I hope this will give you some idea to resolve your issue.
Regards,
Allen

hi guys
maskedtextbox1.mask = "##/##/####"
mskedtextbox2.mask = "##/##/####"
i am using maskedtextbox for getting i/p of date. i have taken mask properties short datetime. my data is stored in sql server 2005 where i have taken data type is varchar(10) in dd/mm/yyyy format (28/08/2007 & 31/08/2007).
my problem is that when i execute the sql query for the selected period in maskedtextbox it does not show correct data.
e.g.
sql_str = "insert mdate into xyz (select mdate from abc where " & _
"mdate between" & " '" &maskedtextbox1.text& "' and '"&mskedtextbox2.text&"'"
"and flag= '" & mflag & "')"
or using where condition it is not executing correct data.
can i get where i am wrong ? if is there any more suggestion for me suggest me.
Thanks
bye

As you are storing the dates as text, you can't do any calcualtions on them (including comparison). You could convert every value to a date in the query, but that's very inefficient.
Store the values as dates in the database, not text.

hi
but it is working in vb6. so i think that it is possible in vb.net also. if i use dtpicker then is it possible ?
Thanks

VB6 handles date/time differently than VB.NET and SQL Server. Who cares if it "used to work" under VB6 since you're not using it now.
You absolutely can NOT store dates in the database as strings and expect to be able to do comparisons and math on those dates, when they are not being treated as dates. Instead, they are treated no differently than if you stored "iwjf948fu04f" as your date.
Using a different control will have no effect since you are STILL storing dates as strings and not actualy datetime values in the database.

Change the data type of database columns to datetime and while storing and changing the values of that field try this statement for dates
Date.ParseExact(txtMasked.text,"Format")
format means "dd/mm/yyyy" i think it is in your case. the above statement will return a Date object which can be sent to database and then retrieved

And you're telling me this why??
Yeah, but this doesn't solve the underlying problem of storing dates in the database as strings.

hi friends,
i developed a Vb.net2003 application & i have some crystal reports tooo. & i made i using default report options.. my porblem is i have some currency fields in the report which show the data with 2 decimal places.. but i want that in 3 decimal places..
anybody have any idea..
cheers..
|
|
|
|

Left Click on currency field and choose "Format Object" option, After that you saw a "Format Editor" dialog box and go to "Number" Tab.
Select "Custom Style" from Style listbox then click on "Customize..." button, After that you saw a "Custom Style" dialog box and go to "Number" Tab.
Select an option from "Decimals:" combox box that you want to show figures after decimal in currency value.
After the selection of your requirement the Decimals Combos value look like this:
Decimals: 1.000
By default currency field shows two (2) figures after decimal.

hi,
sorry to late reply... i already tried the method you mentioned.. & i was in research of that for last 2 - 3 days & atlast i found a small solution but big toooo....
sometimes the currency will show 2 decimals even we set the custum style.. so we have to convert that to string & display it.. so the solution is:
totext({fieldname},3,'','.')
if you want 4 decimal place , replace 3 to 4 , also comman (,) instead of dot(.) replace last ( '.' ) to ( ',' )
cheers..

I've built a VB.NET (VS8 2005) program, and I need it to put the program on Mac OSX (the machine is powerbook G4). I know it is possible with the use of Mono framework. But the setup and converting instruction is frustratingly unclear and confusing, or almost none; can anyone here tell me how to do this, please? Thank You.

The .NET Framework is Microsoft's implementation of the Common Language Infrastructure standard. Mono is an open source project that also implements the CLI standard. Mono is modeled after the .NET Framework but is NOT a 100% compatible replacement for it. You cannot expect an app written under the .NET Framework to "just work" under Mono. The windowing system in Windows is not the same as on any Linux machine, therefor the entire System.Windows namespace in the .NET Framework's base class library cannot be expected to run under Linux. There is an implementation specific to Linux under the same namespace name (I think!) under Mono, but it works differently.
Your app will more than likely need modifications to make it work under Mono. What those modifications are cannot be documented because no documentation can predict what your code is going to do or how it will use Mono's base class library. It's a matter of compiling the app under Mono, see what errors it spits out and fixing the code.

You can also set up Mono on a Windows PC and do your testing there before you deploy to your Mac.

I have developed a simple VB 2005 Utility to Automate the backing up of express databases. Just provide me with a address to send it (I do not have a website) and I will send you the exe file with wizip. It reqires xp sp2 and .Net framework 2 to run.

Nice...
You can just publish its code as an article.

Write up an article and submit it. Bear in mind that many people would probably not be eager to run an .exe that they don't know. With your article, send in the source code as well.

I’m not a programmer or a formal student, rather I’m a 48 year old that loves to tinker, and has no programming experience per say. What I need is to know where to find VB6 examples of a program similar to what I have described below to teach me how to create my application in VB6. If none of them exist or are readily available, than I need some basics to get me started and figure out how to create my desired program using the basic examples provided with the hardware I’m working with.
I’m attempting to create a program that will allow me to use the data from sensors connected to an interface board (Phidgets 8/8/8) primarily pressure & oxygen sensors, and with the data I receive from the sensors I will use that information to control servos with the same interface based on preset values or ranges automatically. The Phidgets Interface Kit 8/8/8 comes with software examples / basic software interfaces written in VB6 so you can receive data and view sensor input changes which I’m doing now. It also makes available similar modest software to control the servos. My endeavor is to use the software / code examples provided in VB6 to create a more advanced program that will allow me to monitor, record / document, automate and control my device through the servos based on the sensor information.
Below are examples of the general interface code and the servo controller code provided with the hardware.

' different inputs and outputs!
' - Note that you can adjust the min/max to increase/decrease the
' apparant sensitivity of the sensor (although it may get jittery
' if you stretch it too far)
