VB App Results Affected Negatively By Windows UI Language?
Dec 16, 2010
I created a VB application in VS2010 using Win7 x64 that performs numerous integer type calculations and displays various results to the user. I have discovered that users running Windows with a different language pack than I developed the App in have problems with how some numbers are displayed and with some of the calculations. Can someone point me to suggestions I can take to ensure the calculations work and numbers display properly regardless of the Windows UI language of the user?
I'm using VS2008 with all updates current. When programming with VB, I set the MSDN Help language to Visual Basic, but I very frequently get results for C#. Why does that happen and is there a reliable way to prevent it? I know C# and can adapt the results to suit my needs, but I thought using the filters was supposed to restrict results. Apparently, it doesn't. I'm just curious; why does that happen?
As I said, I have a vb.net application which runs perfectly fine on Windows XP EN. However, it becomes problematic when run it under Windows XP in German Language. I have a string type in app.config file, it stores a color's RGB value "0,102,255" as a string. When the application starts loading, I will grab that value as a string and use ColorConverter object to convert it to a color as shown the following
Dim oConverter As New ColorConverter
Dim oColor As Color = CType(oConverter.ConvertFromString(My.Settings.MyColorString), Color)
If i want to create a vb.net windows application in multi-language (EnglishArabic). Is there any steps i need to do?I installed the Arabic at my windows XP and I am able to write the labels and the the textbox for example in arabic but is there a way for the controls to shifts automatically?
I want to know if it's possible to change the display language of Windows 7 ( in Spanish) to English and if so how to do it.
I'm having conflicts with non-unicode applications and showing error codes. This is a new computer with everything in Spanish, I'm attempting to put all possible in English.
In my winform app in VB.NET I want to use the localization option. But i have a few questions/problems. I'm using a menu strip to select an other language. But it seems that is doesn't change my menustip text to my selected language. It does change my labels, buttons, and textboxes but menu strips don't seem to change when I choose another language. Also is it possible to get those resx files such as MyForm.fr-FR.resx compiled so it isn't an external file outside my app? Or to get those files in an Language folder at the same location of my app, so i don't have all those fr-FR & nl-Nl folders in the same location as my program?
Everything I know about .Net programming tells me that the behavior I see here is completely impossible. Simple code:
Structure WKSTA_USER_INFO_1 Dim wkui1_username As Integer Dim wkui1_logon_domain As Integer
[Code]....
When I put a break point in here, I see that after RtlMoveMemory, my wk1 contains a pointer to a username, and all the others are 0. This is consistant. Now, if I change Dim test As String = "" to Dim login As String = "" and run it again, wk1 contains pointers to both username and logon_domain.
If I change it to Dim login As String, it contains a pointer to only the username. Depending on what I change that (completely unused) variable name to, I get a different result.
I have always been under the impression that it cannot possibly matter what you choose to name your variable. And that declaring a variable, and then never using it, cannot possible be different from not having a variable there at all.
I've tried this on 2 computers, with consistant results (one on .Net 3.5 and one on 4.0). When I tried converting it to C#, however, I was not able to reproduce it.
I am aware, by the way, that I can just use System.Environment to get what I need about the current user information; this was old VB6 code that was automatically upgraded (and I've edited it a little to make it more trivial).

I'm trying to update a Access database. I'm new to this and I've reviewed an Ado tutorial early today. I'm trying to apply what is taught but I'm getting an error message and I can't seem to get passed it.
In my code I have an Add, Update, and Delete process. The Add and Delete processes work just fine. It is only when I go to update the database that I get the following message."Concurrency violation: the UpdateCommand affected 0 of the expected 1 records."
I've got a simple mdb database set up in Visual Basic Express Edition (winforms) and I'm trying to update data from a datagridview to a database. I've databinded the textboxes to the columns I want in the datagridview and this works great. After some struggling, I've finally managed to have the values updated in every row of the database. But, trying to modify a newly created record throws this error:
"Concurrency violation: the UpdateCommand affected 0 of the expected 1 records"
I mean, it seems as though the error only happens with newly created rows. Because closing the application and reopening it immediatly, I'm allowed to update the values of the cells. I also noticed that the ID of the row is set to "-1" when I've just created a new row. The other rows don't have a negative number for ID. Could this be the cause? Seems as though the row isn't really updated to the database.
So this is the code for the AddRow button Dim newRow As MusicDBDataSet.SongsRow newRow = MusicDBDataSet.Songs.NewSongsRow() newRow.Name = txtBoxNewName.Text newRow.Genre = txtBoxNewGenre.Text newRow.Rhytm = txtBoxNewRhytm.Text [Code] .....
But thinking about it, the textboxes used to update the values of the newly created row are databinded to the database or tableadapter itself right? Could it be that the UpdateCommand fails because the row hasn't really been created properly yet?
I have created an application which ticks and unticks a routing sequence. But whenever I click on my save button after tickin the required, I get an exception thrown at me stating "Concurrency violation: the UpdateCommand affected 0 of the expected 1 records". My code is as follows:Private Sub OKButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OKButton.Click
'Displaying the rows in the dataGridView.Me.myadapter.SelectCommand.CommandText = "SELECT dbo.WR010130.RTSEQNUM_I, " _& "RTSEQDES_I, SCHEDULESTARTDATE_I, DONECB_I, " _& "CLOSEDBY_I, DATECLOSED_I, TIMECLOSED_I, SCHEDULESTARTDATE_I, WCID_I " _& "FROM dbo.WR010130 JOIN WO010032 ON dbo.WR010130.MANUFACTUREORDER_I = dbo.WO010032.MANUFACTUREORDER_I " _& "WHERE dbo.WR010130.MANUFACTUREORDER_I = '" & MoNoComboBox.Text & "' AND (dbo.WO010032.MANUFACTUREORDERST_I = 3 OR dbo.WO010032.MANUFACTUREORDERST_I = 7)"
I have multilingual application that was done in VB2005.We recently had a request to translate the application to Arabic (Egypt), so I have been happily running through all of the forms and changing the layout for Right to Left format.I have 2 forms that are problematic though.On one form, whenever I select Arabic (Egypt), it will automatically switch the selection to Arabic (Saudi Arabia) and try to add an ar-SA resx file.On the other problematic form, if I choose Arabic (Egypt), the IDE will automatically select Chinese (People's Republic of China), then copy the contents of my ar-EG resx file into the zh-CN file, overwriting all of our Chinese translations and layout changes with the Arabic ones.
This code used to work but for some reason it doesn't anymore. I get the error "Concurrency violation: the DeleteCommand affected 0 of the expected 1 records." I checked to see if the values were in the db and they were, by the way I'm using Access 03. I commented out the try/catch block and got the error when trying to update the ds.
im using a sqldataadapter, dataset and bindingsource to connect to a table. i retrieve all records from the database and i change the data on a field then update changes to database. when i try to change back to original value i get a Concurrency violation error (concurrency violation: The updatecommand affected 0 of the expected 1). this is the
Try Me.Validate() Me.sqlBindingSource.EndEdit() Dim slqCmdBuilder As New SqlCommandBuilder(sqlAdapter)
Basically I'm retrieving all the data in my program through runtime, I was wondering how will I retrieve the number of rows affected after an update so I could prompt the user about it through VB.NET
What I'm actually doing is, after an update, if there are no other rows updated then the user can no longer click on the button
When I run the following code I get the error "Concurrency violation: the DeleteCommand affected 0 of the expected 1 records.", I know that this happens when the data is changed in between pulling it from the database and sending it back but, the database is not being edited.
None of the "answers" that I have been able to find, address the problem. I am using oledb to read and update a MS Access DB in an ASP.NET application.I read the member dataset and fill it using the data adapter.I modify the row of data in the dataset.I then use the data adapter to update the row and get the error shown in the subject.
I am an experienced developer using ado.net on sql server windows application via the data adapter, so am familiar with how this should work.
I have searched everywhere and am hoping that someone here at Microsoft might have the answer.
I have recently taken a liking to programming, and have programmed a few games in C#,my friend has asked me to program an application for him to use in his shop. But I have no idea of what language is best suitable?
I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?
My client recently got this error but I can't reproduce it on my pc. Any Idea what the problem could be. I have a master/detail scenario. So I have a grandparent/parent relationship, so when I select a product from my product combobox it displays the relevant results from the Result_Header table in my first datagridview.
Then I have a parent/child relationship so that when I select a result_header item from my first datagridview it displays the child records from the Result_detail table. If i'm adding a new Result_Header and then click save, I search for existing tests for the chosen product and insert them as new datarows into the Result_detail table. then I can update the child rows and click the second save button and it saves what I edit. Quite complicated.

I am working on a program whereby insert, update and delete of database is required, i have been able to do so successfully but the above error occurs when i tried to insert a new row of data into the database and tried to edit it and update it to the database. The database platform i used is SQL server 2005 and i am using datagridview to display my data, my primary key is "s/n" which is an auto number, however, whenever after i insert data into the database, the newly added row has the "s/n" column blank shown in the datagridview and after i edited that row and tried to update it, the error occurs.
I have been looking at the ADO tutorial on this site and am trying to apply it to my own DB. When I run the code above I get this error Concurrency violation: the UpdateCommand affected 0 of the expected 1 records.
when i transfer the bytes sent by the client program to a string the string length is affected.when i put the bytes sent by the client program to a message box. it returns the corrrect text. but when i check the length it will return 8192 or higher. but the actual size is just 5.
