Make Only The Administrator That Can Add Or Edit Users To System
Jan 3, 2012
I have written a program and everything works fine, but I want to make sure that only the administrator can add or edit users to the system. As I see it, I need to add an argument (if statement) to my login button code to disable the add / edit users button on the main form if the user is not Administrator. [Code] I have tried putting my If statement in but it doesn't happen the button is still active even when I login as admin.

I've been wondering, how would you make a vBulletin system that checks what users are online and displays them?
I already know how to make a login system, but can't figure this out.

Every time I make a application and distribute it, Vista users always have to set it as "Run as Administrator" for it to work... Is there any way to make it to where they don't need to do this?

I have a DataGridView bound to a non-SQL Server database.I need to allow users to edit existing records but under certain circumstances I need to intercept the edit and instead of committing and updating the dataset I need to delete the edited record and re-add it as a new record.I have tried using every event I can think of to do this but haven't managed to get it right. [code] This almost works but sometimes completely messes up and re-adds rows twice and all kinds of other bad side effects.

I have tried using every event I can think of to do this but haven't managed to get it right.
The closest I have got is with this:
Dim theRow As DataGridViewRow
Private loading As Boolean = True
Private rowLeft As Boolean = False
Private WithEvents cm As CurrencyManager
Dim copiedRow0 As String
[Code] .....
This almost works but sometimes completely messes up and re-adds rows twice and all kinds of other bad side effects. It seems a really simple thing to want to do but I just can't get it working.

I Fill a DataTable using a SQLDataAdapter then use a BindingSource as my DataGridViews DataSource. My DataGridView contains a ComboBoxColumn named "Status". There are two ways to update the Status column. One, the user can change the value by clicking a cell in the column then the combobox appears and they make their selection. Second, the user can click a button on the form and the Status for all the visible rows are changed to "Exported". I use a stored procedure as my adapters Update command.

i currently have a project that needs to edit a few files in the startuppath folder. on a non administrator o.s., if my app. is installed in ( c:program filesmy crappy little app ), i cannot write to those files. in win7, it does not even ask for administrator approval, just the option to save to my documents.. this can be quite a hassle to work with, specially on closing the app, since i have quite a few files that need to be updated.

I have been getting a lot of crash reports sent from my application that describe System.Web not being found.
I was able to reproduce the problem, and at first it seems that it would be caused by not running .NET 4.0, however, my test machine is running Windows 7 SP1 with .NET 4.0,
How would I go about fixing this problem? Was System.Web deprecated?

This will be my first post on this site, so I thought I would make it a doozy. I have an web application on our site at work that allows users to login to the system, and submit filings for dockets that our state agency governs. Without getting to involve with what that means, they basically upload mostly .pdf files, but there are others that are acceptable to upload as well. The current system that is being used, uses a simple FileUpload and saving it to a folder on the d: drive of the webserver. I ran into a problem that with anyone outside the building/network, the upload is extremely slow and seems to be limited files no larger than about 1.4MB. There have been a few cases where larger file have made it through, but those ar few and far between. I've tried a couple different 3rd party components, but seem to run into the same limits. So, I install the FTP server on the box with the IIS and am trying to go the FTP route using ftpwebrequest.
Below is what I have put together so far:
Imports System.Net
Imports System.IO
Partial Class _Default
[CODE]...
This seems to work as it is at the moment, but I know it has a long way to go for catch exeptions, speeding it up...
1.) The first problem I have run into is if you try to upload to large a file, you get Out of memory error. I'm needing to change the buffer so that it is buffering chunks instead of the entire file. I've googled over and over again and seem to find several good options in C#, but can't seem to convert them to VB. So, could some one give me some idea how to take what I have and change the buffering to use smaller chunks.
2.) I need to catch an empty UploadFile field.
3.) I will eventually be changing this so that it handle multiple file uploads like my current system uses. (Did I mention that I'm new to the ASP.NET and have been programming in .ASP)
4.) As you will notice from my list of acceptable file types, I might have a problem with some needing to be upload as Binary and some not. So I'm going to have to come up with a way to test and change the Requested.UseBinary = False as needed.
I'm sure that I'll find other items as I progress or the big bosses will find other things that they want to add, but for now.... I know that given enough time, I will get all of these items worked out.
By the way, we have a network adminstrator that leave a lot to be desired and most IIS and now FTP I'm having to learn, implement and configure. I'm wondering if there is anything else that could be causing these limits in file size. Since I've tried 4 completely different forms of uploads and they all seem to run into the same limits, I thought there might be something in a router, firewall, server configuration.... that I might need to look into as well.

I haven't been doing a programming for awhile now. But, I was a VB programmer before. I will be creating a tool to log issues encountered by the users of our system. It will be a web based. I'm planning to create it in VB.Net. Any resources that you could share is greatly appreciated. I'm looking for a ready program that I could start with to speed up my programming.

How to get the sign that is used to indicate decimal digits?
For example: in England a number would look like 4,000,000.04 In The Netherlands however the same number would be 4.000.000,04
How can I find out if the users system uses the . or the , to specify decimals?

i have a program where the high scores will be saved in a txt file. of course, if the file is already in use, saving the text file won't work. is there an if statement i can do to check if it is in use? or could i check the last access time, and the last modify time and if the modify time happened after the access, i know its closed, and if the access time happened after the last modify time it is still in use?

I am currently creating an application to track timekeeping (a clock in/out system) and I am trying to work out the best way to do this.
I have a Main Form which contains buttons to ;
- Log in
- Out for Break
- In from Break
- Log out
When a user presses the "log in" button the logon form appears, the user then enters their username and password. What happens next is where I would like the help.
Process is as follows:Click Logon Enter Username/Password Check Logon Form for errors (eg no password etc) Check User is in Database (using SQL query) If user is in DB and username and pass are ok then refer back to the main form to perform Stored Procedure for what the user wants to do (eg logon or or out for break etc). Set label on main form to show user as logged on My question is should I be using a public variable and calling the main form again or in the user logon form having 4 options and using an IF ELSE to select the appropriate Stored Procedure?

I'm making a really complex program that will run only on windows XP (it will synchronize more 100 computers just like a net cafe). How can i make the executable run at startup? For every user not only e.g. Administrator...
1. This is the path for the application startup: Environment.GetFolderPath(Environment.SpecialFolder.Startup) Does the same path exists but for all the users ?
2. Is this possible through modifying the registry ?

Isn't it time to make a separate section for Visual Basic 10 users? For example when looking for the MID string function there are a lot of complaints that it is not implemented in VB, whereas in VB 10 it is.Perhaps a good idea to filter out the VB6 items in a VB10 section?

look at this picture of my index form. It's resized, now you can't see the full labels text.
Example: under the first cover, there stands "Hardbass Chapter" and accetly it is "Hardbass Chapter
21 (2011)". It's not a problem that a peace cut off, but, I want to make that clear to the users,
with adding some points.

In my listbox I get a collection of strings in this format:02406L101G0,967S or 12010C2100,978U. I should get this list on a regulated manner.haracters in the seventh,eighth and ninth place (from left side) always make the numbers eg: 101 or 210. Is there a possibility to edit the list of strings (in listbox or a listview) in accordance with the number obtained as a substring (7, 8 and 9 character)?

I have an app where i have two list views
[Code]...
I clone the information to the empty listview2 from populated listview1 adding quantity via a numeric up/down. That works to a certain extent but problem is it adds another instance of the added item each time I press buy. I would like the items to appear in listview2 according to their index value in listview1. And when I press buy the app change only the quantity in column 2 if the item is already in listview2, if not just add the new item.
