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 have a textbox on a form that is set to allow dragdrop operations from txt files.Basically you drag a .txt file onto the txtbox, the content of the text file is displayed in the textbox.All is working fine, however after the textfile is displayed in the textbox, the text box text is for some reason is highlighted.I don't want the text to be highlighted (or selected) after it's being displayed on the textbox.Second issue, after I close the file that I dragged, for some reason even if I didn't make any changes to the file, it is acting as if the file has changed.In another words, if I open a text file using my MenuItem Open item, and if I do not change the file, If I close the file it's fine it closes.However, if I close a file that I draged into the text box and then close the file without changing anything in it, the stringcompare function is telling me that the file has changed... I can't understand why.

View 11 RepliesI am trying to create a console application that allows me to read the contents of a text file and saving the data by specific name in a set of files. For example, the text file I am going to read is a tab delimited file. Some content of the file includes full name, school, location, and whatnot. I want to save the content by school name in a set of files that have the school names. In this case, everyone that attends "Central" will be saved in a file named Central.txt.Everyone that attends "Central Park" will be saved in a file named Central Park.txt.These are the sub procedures I came up with so far:
Readfile()
'Use StreamReader
WriteFile()
And I think I am on the right track of reading the text file:
Dim objStreamReader As StreamReader
Dim strLine As String
'Pass the file path and the file name to the StreamReader constructor.

Im learning Visual Basic 2010 on my programming class and we reached the part of file handling. Here i tried to make a simple program that can create a text file with the content of what i type on the textbox, basically i create the file if it doesn't exist, and if it already exists i append the content to it. Once the file is saved i can read it using the "Open" button. Unfortunataly, whenever i try to create the file, the compiler gives me an error saying that it cannot modify a closed file, although i've followed up the execution instruction by instruction and i can't find the error.

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
