Can somebody be kind enough to tell me what I'm doing wrong.
I cannot run my (vb.net) applications in any computer but my own. What am I missing?
What am I doing wrong?
I am new with vb.net, in fact I have never had any training at all,
all I have is books, and a lot of help from message boards.
what do i need to run my vb.net app. in different computers?
P.S. Please, do not be
an A.H. if you consider this insulting,
I do not need any lessons in life,
all I need is help with vb.net

Check to make sure the computer has the .net framework installed.

*grin* this made my day. FWIW, it seems a lot of people use the .NET framework and miss the bit where they need to distribute it with their apps. I don't see why the books fail to make this clear, but it's apparently the case.

You've probably built the assembly on your machine whilst logged on with admin rights and thus don't see a problem. However running the code on a different machine (probably with a different userid) - even over the network - will result in a different set of permissions being applied. I've fallen foul of this myself.
There are many objects in .NET that are security conscious (spelling?) and the user running the assembly must be logged on with the correct access permissions etc.
Review your program for anything that could cause a security exception. Also check the framework security settings in the .Net config utility ( Start -> All Programs -> Administrative Tools -> Microsoft .NET <version> Configuration ).

Thank you, Steve.
The problem was that I had the wrong version of framework, I was using ver. 1.0 When It should have been v1.1, on the other hand, I did not know that security play such a major roll in vb.net.

Can somebody tell me why? everytime I finish a project, I have such a hard time to run it in different computers? what am I missing? what am i doing wrong?
I am so embarrassed about asking these kind of questions, but I am new using vb.net, actually I had no formal training, or schooling, all I have is all kinds of books (not all the books are good) and a lot of good help from guys like you, on these message boards.
According to most of the books, one should be able to build a solution and run it anywhere, but everytime I do that; for instance, I try to setup my new app in a different computer and I have all kinds of problems. What am I missing?
Most of the computers where I tried to setup my app. have ".net framework" (according to microsoft that's all I need)but I still have all kinds of problems.
I do not think that I have to installed Vb.net in every computer, Do I?
P.S. Please do not be an A.H. if
you consider this to simple.

But do they have the same version of the .NET Framework installed that you developed the app against? For instance, If you're using Visual Studio .NET 2003, you'll be using the .NET Framework version 1.1. If the computer only has the .NET Framework 1.0 installed, this could cause you some problems.
Other than that, there's really not much else you need to install, short of keeping the computers up to date with the latest security patches.

No, not at all.

I am trying to write a tooltip that can display a hyperlink or change the color of one word in a string. This what I have
Dim MainString As String = "This word is a different color"
Dim stringToChangeColor As String = "word"
Dim range() As CharacterRange = {New CharacterRange(MainString.IndexOf(stringToChangeColor), stringToChangeColor.Length)}
Dim format As New StringFormat
format.SetMeasurableCharacterRanges(range)
format.FormatFlags = StringFormatFlags.NoClip
Dim region(1) As Region
region = e.Graphics.MeasureCharacterRanges(MainString, Me.Font, New RectangleF(0, 0, Me.Width, Me.Height), format)
Dim rec As New RectangleF
rec = region(0).GetBounds(e.Graphics)
Dim stringB As New StringBuilder
stringB.Append(MainString)
stringB.Replace(stringToChangeColor, " ", stringB.ToString.IndexOf(stringToChangeColor), stringToChangeColor.Length)
rec.Width = rec.Width + 10
rec.X = rec.X - 2
rec.Y = 0
e.Graphics.DrawString(stringB.ToString, Me.Font, Brushes.Black, 0, 0)
e.Graphics.DrawString(stringToChangeColor, Me.Font, Brushes.Red, rec.X, rec.Y, format)
' e.Graphics.DrawString(MainString, Me.Font, Brushes.RoyalBlue, 0, 20)
The problem I have is that I have to manually set the number of spaces in the stringB.Replace.
Is there another way?
Please help.
Thanks in advance

My suggestion of the Rich Edit control will be no use in this case. I hope someone else may be able to help.

When connecting a combobox to a datasource like this:
ComboBox2.DataSource = DataSetMainWindowStatusCodes1
ComboBox2.DisplayMember = "statuscodes.name"
And then when you select an item in the combobox how can you automatically allow the record pointer in the combobox's datasource to move to that selected record?
|
|
|
|
|
ComboBox2.ValueMember = <yourkeyvalue>
In combobox2_selectindexchanged(...) get the key value and look it up in your table.
Hope this helps...

Thanks.
When looking up the value in the table I use a For Next loop to go row by row until I find the sought after row. That works but is there a better way to do this?

I have a combobox on a form with the following code:
ComboBox2.DataSource = DataSetMainWindowStatusCodes1
ComboBox2.DisplayMember = "statuscodes.name"
ComboBox2.ValueMember = "statuscodes.statuscodesid"
When an item is selected in the combobox the following code runs:
DataViewUserNames.RowFilter = "departmentsid=" & ComboBox2.ValueMember.ToString
This code throws the error "Cannot find column [statuscodes.statuscodesid]"
If I use this code instead it works fine:
DataViewUserNames.RowFilter = "departmentsid=" & "1"
How can I use the ComboBox2.ValueMember for the DataViewUserNames.RowFilter?
Thanks in advance for any help on this issue.

So you set the property to be statuscodes.statuscodesid, then you asked for it back, and it hasn't changed.

Get the value of the selected item, instead of the valuemember name itself.

I have a single selection ComboBox with only 4 entries which is contained in a VSFlexGrid. I need to have the ability to replicate 1 of the selected entries across several of the rows. It will show up correctly if I manually click within each of the affected cells. Can this be automated???

Anyone out there know a slick way to get a label to display a decimal numeric value, limiting the value to only 1 decimal place to the right of the decimal? I.e.- show 125.5 instead of 125.5665 I've tried designating as currency and single but the only way I've limited at all was to assign the numeric value to a string with limited length, i.e.- x as string * 5. But while this correctly displays the 125.5 it also allows something like 32.34 to display as well.
Any thoughts?

Dim MyDecimal As Double = 125.5665
MyLabel.Text = MyDecimal.ToString("#.#")
will display 125.6
********************************************
Dim MyDecimal As Double = 125
MyLabel.Text = MyDecimal.ToString("#.#")
will display 125
********************************************
Dim MyDecimal As Double = 125.5665
MyLabel.Text = MyDecimal.ToString("#.0")
will display 125.6
********************************************
Dim MyDecimal As Double = 125
MyLabel.Text = MyDecimal.ToString("#.0")
will display 125.0

You ROCK!
Thank you so much for the assistance!
Don't suppose you know what size I should make my forms so they fit PDA screen? I know my PDA has a 240x320 pixel screen but the form sizes in twips. Can't figure out the conversion.
Thanks again for the decimal solution.

If you are using VB.NET which I assume from your previous post, then all control sizes should already be expressed as pixels. VB.NET does not support any coordinate system other than pixels.
In VB6 there are TwipsToPixelsX and TwipsToPixelsY functions that will convert twips to pixels based on the current screen resolution.
