I recently upgraded a project that did a lot of screen manipulation. Controls (hundreds in different configurations were loaded, aligned and displayed using the ".left" and ".top" commands on the control.
In many places there were alignments done based on other things and an offset, for example,
frachamber(0).Width = ((ID_WIDTH * 2) + (SLOT_WIDTH * 2) + 400)
after the upgrade I get
frachamber(0).Width = VB6.TwipsToPixelsX((ID_WIDTH * 2) + (SLOT_WIDTH * 2) + 400)
I would like to simplify and get rid of the twipstopixels and just go with pixels but am not sure how to convert my offset values (400 in this case) It looks like someone spent a lot of time figuring out all these offsets in the past, something I would like to avoid if possible.
any idea how to convert, say 100 twips is about this many pixels? (I guess they would be needed in both X and Y). In debug mode it will not tell you what the converted value is in pixels.
Thanks
sorry, upgrade from vb6 to .net

That is how it is supposed to work. Is it not doing that?

You write the code to store in the DB, so what is the problem ?

I have a task that i have to synchronize/update both my web(asp.net & SQL 2005) and windows application databases(VB.net & SQL 2005).
My scenario is my web app. and windows app. both accept reservations. I want any reservation happen to my web or windows app will reflect to both databases(online & local) at the same time.
Please help me.
Thanks.

I would look at using SQL Server replication or if that is not possible, writing INSERT, UPDATE and DELETE triggers for each of the tables that need syncronising. Better still why not use the same database for both apps?

Like Steven said, best is to use a single database for both. In fact, it is useless to build a separate windows form. Just make a separate section in your web app with login for administrators / employees, and build the form there.
Using xml could be an alternative approach. Handle web reservations as orders, and have your web app send the necessary information for the reservation in an xml file.
Vice versa, you can send data about existing reservations / open capacity in xml files to your web server.
Obviously this approach would not nearly be as real-time, so you would have to figure out a rule about how to handle double reservations. For example an approval queue.
My advice is free, and you may get what you paid for.

Single database will do and write a webservice which handles database layer and business logic layer. Webservice can be called from web and windows applcation. So even if you change the presentation layer (web or windows) you can do that.

Seeing as you can't do your own job, perhaps you need to pay someone to do it for you ? I mean, we're here to help, not to do your job. What have you tried ? Anything ? Did you google it ? Do you have any idea what you're doing ?
You have asked two questions.
1 - output to notepad. I assume you mean output to a text file ? File.WriteAllText will do that. Process.Start will open the file in notepad.
2 - formatting your data. Your best bet here may well be to read your data, then iterate over it and build the format you want, given that you have to build it into a string to save it in the first place.

Use a select statement (query) or stored procedure to open up a datareader, then open a connection to a text file using the filesystem object. Use a loop to read through the datareader and append a line to the text file for each item you want.
Here's the pseudo code - you fill in the rest.
Open datareader
Open file for Append
do while not datareader.eof
file.write("Name: " & datareader("Name"))
file.write("Designation: " & datareader("Designation"))
file.write("Salary: " & datareader("Salary"))
file.write("------------------------")
loop
file.close
datareader.dispose

Good day! I have a problem using DataGridView. Here's my code.
Public Class MyLibrary
Private _dgv As DataGridView
Private _recordBLL As RecordBLL
Private _dt As DataTable
Public Sub New()
Me._dgv = New DataGridView
Me._recordBLL = New RecordBLL
Me._dt = New DataTable
Me._dt = recordBLL.PrincipalMember
Me._dgv.DataSource = dt
'********* Error is displaying here ********
With Me._dgv
.Columns(0).Visible = False
.Columns(1).Width = 200
.Columns(2).Width = 600
.Columns(3).Width = 150
.Columns(3).DefaultCellStyle.Format = "MM/dd/yyyy"
End With
End Sub
ReadOnly Property MyDataGridView() As DataGridView
Get
Return _dgv
End Get
End Property
End Class
And I encountered this error. "Index was out of range. Must be non-negative and less than the size of the collection." But the data is displayed in the grid.
Pls. help me. Thank you in advance.

Well, I guess you don't have four columns at the point that this code is run. What makes you think that you do ?

I already bound the grid with datatable and the result reflect in my datagridview control. And I saw the columns and rows.
Do you mean I need to create set of columns and bind it with datatable?
Thank you very much to your reply.

No, if you have databound, then you should just have the columns. However, it's clear you do not, that's what the error means. So, you need to work out why, that's what your issue is. Which line blows up ( that is, do you have any columns at all ? )

I'm using a fairly basic Select statement that is bound to a datagridview )SELECT ID, Desc, Default, Name FROM Table1)
The ID column is an auto-incrementing integer column in Table1. The dataset is strongly typed with commands for insert, delete and update.
Winform setup:
BindingSource1.DataSource = dsData
BindingSource1.DataMember = Table1
Datagridview1.DataSource = BindingSource1
I'm confused on how to properly handle inserts (specifically with the ID column). I'm assuming you would insert the row and return the ID to set the ID column in the grid but am a little lost on what method(s) to use (esp. to cancel the addition in the case the user presses escape). Just looking for a little guidance.
Hope this question makes sense.

Unless I am horribly mistaken (and I have been known to be), the database will handle the ID column for you, as you set it to auto increment.
So the user can just go ahead and update, insert and delete in the datagridview = the dataset, and by simply calling dsData.Update() somewhere / somehow, the changes will actually be made to the database. Up until that point the user is free to change his/her mind.
To prevent problems, you could just set the ID column in the grid to Read Only.
My advice is free, and you may get what you paid for.

Incase anyone runs into this, SQLCE doesn't support Insert; Select statements from within the tableadapter.insert command text property (as opposed to your standard SQL connections).

hope a answer. \regard Gerrie

Yes, this does sound pretty easy. Question is, what are you looking for ? If I wrote the code, how would that help you ? XML is manipulated using XPath and the XMLDocument class. Googling those things will tell you how to work with XML.
