Hi,
I tried several ways to get it to work. Finally, it appears to me that in this case databinding might not be the preferred approach.
So I tried to fill a datatable by an sql-query and this...
-
thanks for the sample code. I'll go through it.
-
yes, that is correct.
the lower grid should show various fields of order positions. In addition the order positions table has a field that shows the status of the order, eg. ordered, confirmed, in...

I went through your codebank and compared. It works for the first part and I believe I understand the mechanism. Below is my code:
'Firmentabelle: Data viewed in Combobox

Hi,
I have three datatables which are related as you can see in th picture.

With Bindings I can select customers (upper combobox), which shows all orders of that customer in the combobox...

I deleted the dataset and added it again, if this is what you suggested. It worked.
thanks

Yes, I have changed from WWS to WWS_Buchung. Below see the corresponding screenshot

Hi
When I make changes in the *DataSet.xsd and run the program I get the error message:
"WWS" is not a member of "<Default>". in WWSBuchungDataSet.Designer.vb.
The corresponding command in the...

HI Guys, thanks for iinput.
I use the timer version where the timer will allway be restartet and it works fine.
-
Hi,
I have set up a client that connects to a server to transfer data in both direction (TCP/IP with TCPclient).
Now, I would like to set up a timer to check if the connection still exists if...
-
thanks for this nice example. I think I now better understand the way to program with sockets. It works now!
-
I have tried it. But this does not seem to send the data. It looks like the connection had been closed, although the networkstream.canwrite and client.connected returned true.
-
Hi,
I have TCPIP connection using TCPclient and TCPlistener in a seperate thread.
It works fine if I allways open a new client after each roundtrip (sending /recieving or recieving /sending).
I...

the application runs in a manufacturing line and includes a planning system (gantt chart). We keep a backup copy at a remote location. So we do one update in the morning when the operation starts and...
-
I am sorry if I could not explain well enough what I am trying to do.
When I start the application that uses a ms access as db I want to make a backup that is sent to a different location. In the...
-
I think I found the trouble maker!
When I start the program I also start an email routine that sends the database in use to an external address for backup. This takes some time and blocks the...
-
I further investigated and there are indications that vb, windows or MSaccess blocks the connection or the datatransfer. I found as follows:
when there is a problem
- I can only open msaccess...

For Each row As DataRow In dt.Rows
MsgBox(row.RowState.ToString)

to call the RowStates helped. It looks lilke sometimes the rowstate is still in "modified" state....
-
thanks for input. I' ll use 'for each' to walk through the table and try to understand the problem
-
I use the automatically generated DataAdapters and their methodes like artikleTableAdapter.update(DataSet.artikle) where artikle is the datatable.
This seemed to work so far without any problem. In...

Hi,
I encountered a strange behaviour trying to update to MS access.
I use VB 2010 express, Datatables are bound using bindingsource to a datagrid. Update is handled using bindingsource.endedit,...

HI,
I want to send a picture to a webbrowser and created the server in VB, which works well.
To get the required MIME format of the picture I loaded it as attachment, sent it to myself opened the...

Hi,
I am an aboslute starter in HTML.
I have programmed a server to show text and picture in a browser using VB.net. If I call the server using local IP adress vom webbrowser in VB text and...

I went through my project and tried to understand what you explained and I found the following code which I am not sure what they are doing:
Form1.designer.vb
Private Sub InitializeComponent()...
-
I went to your Blog: Data Among Multiple Forms. Very good explanation. Based on this I will have to recode a lot, but so what it will make it better.
-
Hey, that's great. Could you kindly give me some hint, how to program, so all forms share the same data. I guess this way all bindings should be updated concurrently as well. This would make many...
-
thanks for input.
So, this means, if I correctly interpret what you are saying, when I copy and paste a table from datasources to a form and tableadapter and bindingsource are created a new table...
-
Hi,
I ran into a strange problem and hope that somebody can explain the mechanism and hopefully help with a solution.
I have one dataset with tables. I also created two forms, form1 and form2, with...
-
I noticed that the unneeded db PPS04a was present in the db explorer. Because I only used the database sources windows I didn't see it. But it was displayed after launching the project, which give me...
-
Obviously, the problem occurs before the form is loaded. Is there a way to catch an early exception, lets say right after the 'main' program, if this exist (I could not find it)?
-
Hi,
When I start a project a data connection is loaded and closed which should not exist anymore.
The PPS04a.accdb is not used anymore and I could not find a place where it is referenced. All...

-
the version control that you propose sounds interesting, but I do not quite understand how to do it. Could you provide a code snipped that explains it, please.
thanks

Hi,
I have a running application based on VB which uses MS access as DB. The application is further improved and tables and fields in the current db are changed due to needs. I am looking for a...

Hi,
I found a wisiwyg editor in the internet. It is called "BlueGriffon". It seems to support a number of controls. Now, I will try to include the HTML-output to my vb-server.
Is there any...
-
Thanks for the hint cordova. I am going to look into it.
-
I you are right. I am developing an application in vb and data should be accessible via webbrowser. I got the impression that asp.net would translate the form into HTML. But I can't get asp.net to...

Hi,
meanwhile I managed to get client and server set up to communicate whith each other and also to receive calls from firefox. I worked with tcpclient, tcplistener and httplistener.
Now, I...
