Multiple FontStyles For A User At A Time
Dec 19, 2009
I've got an application in VB 2008 with, 1 richtextbox, 1 toolstrip and 1 menustrip. My toolstrip has many buttons, 5 of these being a: bold button, italic button, underline button, strikeout button and a regular button. However it is only possible to have ONE fontstyle at a time. If you want Bold AND Italic, it is impossible.
[Code]
Make it so that the user can have more than one fontstyle at a time. Make it so that the user can click the button again to remove that fontstyle instead of clicking the "regular button".

I have a program that allows a user to select a program to run at a certain time for a specific amount of time all choosen by the user. Everything works with the exception of if my program has launched the other program, my program become non-responsive. Meaning I am not able to look at that window again. Not that one really needs too, because when time is up my program closes the program it opened, then closes itself. I just want to be able to see my program when the other program is running. how to do this and perhaps drop me some links, that would be wonderful. This is what I have coded, but like I stated there are no code errors.

I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?

I'm using
Days = Dat2.Subtract(Dat1).Days
where
Dat2 = today
Dat1 = installed date
to trace the days of a program installed in user's computer.However, the user can changes the system time of his computer to a advancing date. How can I get a SNTP time from internet to solve this problem?

I have a oracle database. I use the OracleDataAdapter(Oracle.DataAccess.dll) for select, update, insert, delete operations. I don't set any (table) locks on my own(I only start a transaction). I have a oracle table named "test" with the entry "test1".
Now my question: Can Person A read the entry "test1" while Person B is updating/deleting the entry at the exact same time? What happens in the worst case? An old match/empty match or can it cause any kind of exception/error(e.g. "TableLocked-Exception")?

writing user info such as user, computer name, date, and time to an acces database using a button click event. Then use a query to check if the user has accepted the aggreement. If the user has accepted the aggreement then call a vb.exe that display the aggrement. I have a login script that runs the vb.exe and uses a button click that records the user info to a csv file, but if the user has already agreed to the policies I do not want it run again.

I thought I postet this yesterday but I can't find my thread so if this is a duplicate please point me at the original one. Background: I need to create a user account and Modify it's registry before the user logs on the first time. Creating the account is done by using the Winnt provider (works great). To create the profile I'm trying to use Process.start to launch a process as the newly created user. With the use of loaduserprofile property the users profile gets created and i can do my regwrites without problem.

I'm designing a PC-based app that has a little local database. I'm using VB.NET with SQL Server Compact Edition. The user will only ever have access to one database file, because it's all about storing a user specific data. However I'm thinking of the situation where there could be multiple users that access the PC, each with their own Windows account. So ideally I'd need separate database files for each User.
I'm not sure how to implement this. I was hoping to deploy the 'empty' database as a ClickOnce deployment, but I can't see how I can have a database per user doing this. Also I'm not sure where to store the database files anyway. perhaps in MyDocuments for each user? Or perhaps I need to stick to just one database, but add a 'User' column into every table, so it can hold data for every user. I didn't want to do this though - because I wanted to keep the nice separation between the data offered by physically separate files.

How can i code my application so that it can handle two sets of key events at the same time? For example, if I was making a game where one player used the WASD, and the other the arrow keys for moving, how can i make it so that both can move at the same time? The code I used only allows one to move at a time.. (key press event, If e.KeyData = Windows.Forms.Keys.down then.... etc)

Here is the code:
CODE:
What I want to do is I want to post to different referers one at a time and of course the links will be provided by a richtextbox(i.e. richtextbox1.lines(i) ). I will use only password(which will be chosen by the user from a combobox(combobox1.text)) because the username is harcoded. This is what so far ive come up with but it always gives me the result of the first line(or referer) from richtextbox1. I think there might be a problem with my "FOR" code.

The code is a long one and is there any other way to code all of them at the same time or should I code it by copy and paste? The names of the button are in sequence, Button1 - Button2 - Button3 - and so forth until Button80

Is there any way to download multiple files at the same time from a remote server? How I am doing it currently is I get a list of files from the target folder on the server then I loop through that list & download each file 1 at a time. For 100 small files it takes about 45 seconds. I'm guessing that the bulk of the time it takes is logging in to the server for each file to download, so 100 files means it has to login, download & logoff 100 times. Is it possible to login just once, download the 100 files then logout?

I'm writing a scripter using VBScript, that should be able to execute multiple scripts at same time, running on own threads.
The issue is, I DO start those scripts on different threads, but their sleeps still seem to affect the other threads too.
For example, let's say I start 2 scripts
In the Main event
NewScript1
NewScript2

A couple of questions about the FolderBrowserDialog in VB .NET Express 2005...
1. How can I make it so this control allows selection of multiple folders at a time?
2. It remembers the folder I selected last time (in the same session), and highlights that folder, which is good, but that selected folder appears near the bottom of the window. Is there a way to make it so the previously selected folder appears in the middle of the window (i.e. the scroll bar is further down the window)? See screen shot attached for how it currently looks when the window opens.

When I setup the event using DDay.ical I can successfully send the events to a user's outlook. The problem arises when multiple events are setup at the same time. When this happens all emails are updates to the original task, not new tasks.
I tried adding a name to the event using the .Name property, which results in the event email being an unsupported calendar invite.
