I found one solution that , if change user rights manually then this problem solved.Follow these step to change your account settings.Control Panel-->User Accounts and Family Safety-->User Accounts-->Change User Account Control settings-->Never notify(Set tab to never notify).After this change need to restart system.Now can make all changes like windows XP into Windows 7.can also make changes into program files.
Its working fine, but need to make these changes manually in OS.but its not efficent solution. So if any one knows how can make these changes by coding that will nice.
i was just wondering if there was a way that i could compare data stored in a text file such as usernames and passwords with data input into text boxes in visual studio vb2008?
View 6 RepliesOur application is using VBSQL.OCX on Sql server 2000 to create temporary tables and load pipe delimited data from a text file with predefined format into the tables. It is failing intermittently doing this. 99% times it works perfectly. But on occasions it does fail with error. Once the process is rerun with the same input file it runs successfully.Basically the architecture is of Store/Head Office where there are around 200 remote stores sending set of data files to the Head Office. At HO our application sequentially processes each store which has all the set of files received, creates a corresponding table, loads the data from the file into the table and moves onto the next store.If it is for some reason not able to load the file for a store, it gives a failure message and continues with next store.Error which the OCX throws is "Attempt to convert data stopped by syntax error in source field"

View 2 Repliesi have a project that requires me to make a unit converter. the units should be defined within the program. i have reached a point where i save the defined units in a text file for a simple example converting meters to kilometers where it gets divided by 1000 i made the program to save the a string in a text file to represent that as:
meter,kilometer,0.001
which means it gets multiplied by 0.001 anyway the problem that i'm facing that when i want so save another units in the same file the previous units gets deleted. how to make the program update the text file that it adds the new defined units in the same file but before that it looks in the test file if the unit is already exists and if it does it will replace it with the new value
is it possible to read a string just before the second comer? foe example if the string in a file is: meter,kilometer,0.001 it will read it as: meter,kilometer and is it possible just to read the last value? 0.001

I'm writing some text to a memory stream and need to modify it once in the memory stream The reason I can't modify prior to adding to the memory stream is that it is from some 3rd party component. Here is an example:ms = New MemoryStreamdoc.Save(ms, SaveFormat.Html)I need to do some modification to the resulting text that ends up in ms. Is there a way to convert the contents of ms into a string, and then back into a memory stream once modified?

View 1 RepliesWhat I am trying to do may be better for use with SQL Server but I have seen many applications in the past that simply work on text files and I am wanting to try to imitate the same behaviour that those applications follow. I have a list of URL's in a text file. This is simple enough to open and read line by line, but how can I store additional data from the file and query the data?
E.g.
Text File:
link1 - 0
link2 - 0
link3 - 1
link4 - 0
link5 - 1
Then I will read the data with:
Private Sub ButtonX2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonX2.Click
OpenFileDialog1.Filter = "*txt Text Files|*.txt"
If OpenFileDialog1.ShowDialog() = DialogResult.OK Then
Dim AllText As String = My.Computer.FileSystem.ReadAllText(OpenFileDialog1.FileName)
Dim Lines() = Split(AllText, vbCrLf)

Am I going completely the wrong way about storing the data after importing from a text file?
I'm looking for a way to mirror text (like how Stack Overflow provides a preview of the text being entered, as it's being typed). I also need to be able to modify the texts output environment (whether it be a textbox/messagebox/etc.) for background/text color (selected from a dropdown menu). Suggestions on the best way to go about this? FYI I'm using Visual Web Developer 2008 Express and it's an aspx page.
