The Express Editions weren't meant to build production apps. They're meant to plaay around with so you can get an introduction to the languages they support and the .NET Framework. Those Editions don't even have project templates for Windows Services, Web Services, ..., just Windows Forms.

Just because they weren't ment to build production apps, doesn't mean it isn't happening. My article is on the windows setup project. I never did one on the web setup. So from my perspective it still make sense since all you have is a windows project. You probably want a way to deploy it. I can understand the windows services not being there. Anyway, I guess it doesn't have to make sense. I am sure somewhere somebody said, "hey look if we leave the windows setup project out of the express version it will save us like half a cent somehow and that adds up you know?" I am sure that nobody is going to buy the full version of VS just so they can get windows setup projects.

You can put one together, but it doesn't mean that it'll work. The designer support for Setup projects isn't in the Express Editions.

hmm, should be able to get something running I would think, I suppose I could just use clickonce for the purpose of the program, it'll work well enough, just means I'll have to rebuild all my datasources, as I'm not a fan of having MDF files in a roaming profile, heh, suppose if I'd set up the SQL properly at the start it'd actually work better as click once...

If you use the tool for something that's it's not intended for, is that the tool manufacturers fault?

A problem with an array populating an unbound DGV

True, I guess their logic doesn't match my logic in this issue. I guess I tend to try and look at the big picture and do what will help people out in the long run. But I am not so sure that is Microsoft's objective. I am pretty sure they are in the business of making money anyway they can, but that is in part why they are so successful.

THe error message is:

"Index and length must refer to a location within the string.
Parameter name: length"

Source: mscorlib

The lines causing the error are:

Dim row() As String = {rowBuild(0), rowBuild(1), rowBuild(2), rowBuild(3), rowBuild(4), rowBuild(5), rowBuild(6), rowBuild(7), rowBuild(8), rowBuild(9), rowBuild(10), rowBuild(11), rowBuild(12), rowBuild(13), rowBuild(14), rowBuild(15)}

Me.dgvData.Rows.Add(row)

This is loading data into an unbound DataGridView. The declaration for rowBuild is

Dim rowBuild(15) As String

Each rowBuild element has data in it, so I can't see what is wrong.

Any ideas???????? Confused | :confused:

Re: A problem with an array populating an unbound DGV

Using the code you've supplied, I can't duplicate the problem. I actually can't BREAK it in any way unless I fail to define the columns in the DGV before I add the rows.

With DGV1.Columns
    .Clear()
    .Add("Col1", "Column Header 1")
    .Add("Col2", "Column Header 2")
    .Add("Col3", "Column Header 3")
End With
 
Dim row() As String = {"Data 1", "Data 2", "Data 3"}
DGV1.Rows.Add(row)

Works perfectly. If you don't create the columns first, it'll bomb out with an InvalidOperationException - "No row can be added to a DataGridView control that does not have columns. Columns must be added first."

I'm using .NET 2.0... There's got to be something else about the DGV setup or about the data that we haven't seen.

Hi Dave, I don't have a problem with the column headers, but just so you can see, the columns are created thus:

dgvData.Columns.Clear()<br />
dStartDay = mv_dCurrentAnomDate.AddDays(-2)<br />
iStartDayNumber = Weekday(dStartDay)<br />
dgvData.Columns.Add("Unit", "UNIT")<br />
For iLoopVar = 1 To 15<br />
    dgvData.Columns.Add("D" & Format(iLoopVar, "00"), Format(dStartDay, "dd-mm-yyyy") & Chr(10) & Format(dStartDay, "ddd"))<br />
    dgvData.Columns(iLoopVar).DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter<br />
    dStartDay = dStartDay.AddDays(1)<br />
Next<br />
dgvData.ColumnHeadersHeight = 45

THe only error message I get is this "Index and length must refer to a location within the string.
Parameter name: length"

Source: mscorlib

To be honest I don't actually understand what the error message is trying to tell me!

Hi Dave,

My face is seriously and completely covered in egg!! I apologise for wasting your time as it transpires that the error is actually occuring in the Cell_Enter event and I never saw this because I was stepping over the .add(row)

A sad case of not being able to see the wood for the trees! D'Oh! | :doh:

Thanks again and apologies again.

I would appreciate any strategy that would allow me to locate a string within an rtf document and identify what printed page it would be on.

I am trying to programmatically fill in page numbers for a Table Of Contents within the document.

Thank you,

Brad

That depends on alot of things -

The font used for the text, the dpi of the printing context, the printable area of the printing context, the line height of the text.. there's no straightforward way to do it.

The best way I've found to do it is to actually execute a print on the document and count how many times OnPrintPage is called and the character indices at which the print boundaries get determined.

localhost is a synonym for the local machine. It's IP address is 127.0.0.1

You can use Yahoo or Google as a host, but not localhost (because localhost is local to you)

need to display stdout messages

19-Apr-07 5:00

This is very easily done with the Directory class and it's Delete method.

Directory.Delete(path, True)

The True parameter is necessary to delete everything inside the target directory, all of it's subdirectories and files.

Hello,

I'm writing a kind of editor app to design and execute batch processes. I need a control (or similar) that would allow me to display stdout messages on the lower part of the screen, like VisualStudio does when compiling etc. (Where) can I find something like this ?

Hope the question makes sense, I'm just a .net beginner.

Thanks,
Miguel

A TextBox??

It sounds like the problem you have isn't displaying the messages, but getting them from the Process that you're launching??

When a process writes text to its standard output(stdout) stream, that is normally gets displayed in the console window. You can redirect the StandardOutput stream property of the Process class, you can manipulate or even supress the text. To use this you have to set RedirectStandardOutput property of ProcessStartInfo to True.

Here I ll give you some sample code (..)

Dim oProcess as New Process
Dim oProcessStartInfo as New ProcessStartInfo("some executable name")
oProcessStartInfo.UseShellExecute = False
oProcessStartInfo.RedirectStandardOutput = True
oProcess.StartInfo = oProcessStartInfo
oProcess.Start()

Dim oStreamReader As StreamReader = oProcess.StandardOutput
Dim myString As String = oStreamReader.ReadLine() ' Or here you can use ReadToEnd() method

Suresh
