How do you reinstall and write over the previous dataset from a click once app? I assume that in a purchased version there are some added features with deployment and install. I am needing to delete the previous dataset when I uninstall. Currently,I am getting the first dataset AFTER I reinstall which leaves me with the mistakes and reason for reinstall not being fixed.
View 1 RepliesI had created two button for the previous and next function. I think my logic is correct and the programming did not have any error but still, i failed to navigate through the data.[code]The problems are when i hit the next or previous button, it did not jump to the respective record and it keep on showing the 'end of record' or 'beginning of record' as programmed.
View 1 RepliesI have the following code which is linked to a previous and next button, however I need to have a loop so that if a next button doesn't exist then it does nothing as it currently ends the program with an error when it gets to the last record and I click next or previous.

View 1 RepliesHow do you restore a dataset to the previous state before updating the database with a data adapter? I have a concurrency update problem that I believe to be caused by this. The update fails during the update and a rollback command is issued using a SQLTransaction object. However, now the rowstates of the rows that did not have errors have been changed to unchanged. So this record is no longer availible to be inserted into the database. When I updated the value that could not be null and then test the second update which runs just as the first does then I get a concurrency error. The update code is below:

I would like to make data binding using BindingSource whereby whenever either Next Button or Previous Button is click the BindingSource position will change to display the data at that position.
I know that if I want use a loop of the BindingSource I could do somthing like vb code below but I am not sure if of binding it seperately. I usually bind it through the properties but this I cant because is an image column which I want to bind and I have to us memorystream to display it to reduce memory usage, so I asign it to arrPic so that whenever the BindingSource position changes the image column will be asign to arrPic.
Dim MyRow as DataRowView
For Each MyRow In dtView
'only use non-repeating names
CurrentPicture = Trim(CStr((MyRow("FileName"))))
If CurrentPicture <> LastName Then
[Code]...
The BindingSource filter the picturenames and add to a listbox. One name may contain about 4 or more pictures so when you select a name from the listbox the bindingsource populate only the pictures have the selected name and you can navigate forward and backwards.All what I want is how to bind a column to a textbox or picturebox by code. I know if it is a dataset I can declare a datarow and bind anything to the columns.

View 4 RepliesSo although we have plenty of keys from our subscription, to minimize tracking and confusion we just want to use2 or them over and over as we install, test, extended test, wipe and reload. Eventually we would have to recycle any way. Much of this will be scripted /automated and we were wondering what kind of problems we will run into for the activation cycle (human intervention required, phone call, etc.) Mostly working on Win7 (all versions) but still need to do some Vista and even XP.

View 1 RepliesI am using a dataset control on a form to store and read data from XML files. So far I use the following to write info.
VB
Dim drow As Data.DataRow = DataSet1.Tables("item").NewRow
drow("path") = strFilePath
drow("id") = strCreationDate
[Code]..
The problem is I need to APPEND data to the same file. What I do now results in the same file being overwritten. I am dealing with large amounts of data, so I would love a way to append to the file without the need to re-read it with each save.code lines 1-4 are in a loop so that at one time, they add a few hundred rows to the DataSet. After that loop is when the save takes place. However, I want to run that loop again and again every so often to update that same file.
I loaded a dataset (just one table) from the database. Then I modified f.e. the rows from 5 to the end and add 4 new rows. Now, I would like to write back the dataset into the database.

One method I used was to fill the textboxes from an xml, but now how do I write it back to the xml once the user has changed the data in the textbox?

im creating a high score table. Although i dont know how to write to a text file.What i did first was i created a text file in vb's resources and thats about it.What i want the program to do is:when a user clicks e.g. Button1. then the programs gets the score from textbox1.text (currentscore) and textbox2.text (out of)
then saves it to the text file.I tried the following
Dim oFile As System.IO.File
Dim oWrite As System.IO.StreamWriter
oWrite.WriteLine(TextBox2.Text(""))
EndClass
I have the following code, which I run everytime I want to add a new line to my text file, but it is deleting the previous data in the text file every time I do it.
Dim stFilePath As String = "C:file.txt"
If File.Exists(stFilePath) Then
Else
File.CreateText(stFilePath)
End If
Dim ioFile As New StreamWriter(stFilePath)
ioFile.WriteLine("{0}: {1}", DateTime.Now, "test message")
ioFile.Close()
i would like to be able to double click on a label for a text box and write a value into the .tag property and then change the color surrounding the label.for example.. if the user double click the default label..(which looks like the stardard label) then I would write a "1" to the tag property for that label, and at the same time, change the line color surrounding the label to red(maybe even changing the thinkness of the line).
when the user would double click the label again.. I was see that it was already selected and change the setting back to the default.
So basically i need to make a loop that only lets the user click it ten times then gives the answer to them.i was gonna use a DO loop that looks like this so far.
Dim counter as integer
counter = 0
Do until counter = 10
loop
and after that i'm kinda lost on what to do, i know that its needs to be if you click btnenter 10 times give the right answer and then your done.
