VB Human Resource Database Connection?
Apr 22, 2011
This is a homework assignment, but i want help, not answers. I made the form for this project, but my instructor supplied the code, the problem is, it doesnt work haha I have been trying to troubleshoot this for the past couple of hours but my problem is that when it comes to VB, my major weakness is database connections. When i run the code the form does not pull any data as it is suppose to. My thought is that it might be outdated because the instructions i got told me to "open Visual Studio 2005" so i dont know if the VB code from 2005 to now has changed? I have VS 2010 and SQL server 2008 R2. My first thought was that maybe my connection string was wrong, but i put in the same information that i use to connect in sql server management studio and i read that if the connection string was wrong VB would throw an error, is that right? With all the code entered in VS, it doesnt show any errors such as syntax errors etc.
It does error out when i run the program though, im guessing because when i click update, or edit, it cant because there is no data in there to edit or update. I'm wondering if someone could review this code and tell me why it isnt pulling data and explain it to me so i can understand. I will attach my whole project instead of pasting the 500 some lines of code.

After running the following sub (VS debugger), I try to detach the database in SSMS, but it shows the connection open still and won't let me detach. If I close program in debugger, the database shows no connections. I check the dataadapter's connection in the finally block and is shows closed. What gives

i am using access database for my program. now i have connected to the database in MDI form of main exe, and ir also works, user can log in, it gets verified etc etc etc. now here is the problem, when i load a form from dll and try to use any sql query on that form, i get message, "database connection is not opened". so what i did was, i added the connect() (a function i designed to connect to database) in the load part of the dll's form, it made the trick, query's started to run, everything went fine, and when i reload the form i.e after closing the form, i load it again from MDI form, i get error, connection already open..

I have a app that is multi-language.I'm already using the GlobalizationLocalization and one resource file for the strings.In the application i'll have several groups for the users, but i don't know in the beginning how many groups the application will have, this groups will be added to the database.I thought in adding to the resource file generic names, but like i said i don't know how many groups i will have neither the name, so i'm kind of stuck.

I am trying to simulate human temperature taking. Basic I just need a button, a textbox , a progress bar and a timer. What I want to do is that when the button is clicked, the progress bar will slowly increment and after it reaches maximum, a random number in the range 35-40 will be generated in the text box.
Now so far, this is what I've done:
Public Class Health
Private Sub Health_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Start()
[Code] .....
So this is suppose to be a temperature gadget for kids and therefore when a certain amount of temperature is reached...an alarm is sent to the parents. So the progress bar is working fine. The random number generator too. A "sent" dialog box is open if the temperature is >38.
1-The number is working. But I would like the number to b e generated AFTER the progress bar reaches maximum.
2-The sent dialog box is open basically the moment I click on the button to start the progress bar (if the num generated is>38). And it keeps up looping and opening.

I need to refer to some strings using an "indirect string" in the registry. It should be in this form:
@filename,resource
MSDN: "If the resource value is zero or greater, the number becomes the index of the string in the binary file. If the number is negative, it becomes a resource ID."How can I find out either of these numbers for my resources that only have names in VB? I also need the ID/index for the exe's icon.

Greetings, I'm looking for a way to encode a string into HTML that uses human-readable tags such as ê (=ê). At the moment, I am using the HttpUtility.HtmlEncode() function, but it appears to return numbered tags instead of human-readable ones. For example:
Dim str as string = HttpUtility;HtmlEncode("vente - en-tête")
'Expected: vente - en-tête
'Actually received: vente - en-tête
Is there a setting or function in ASP.Net to encode a string into HTML resembling the first comment?
EDIT: I am looking for this kind of functionality because the text is saved HTML-encoded in the database. The text comes from a bunch of MS Word documents that have been converted to HTML.

I have USB device that is detected as human interface device (HID). The device has one button on it. I want to have more of same devices attached to one PC. I would like to simulate a click on that device (it is not a mouse!). It should be simple using Windows API, but I just can't seem to find an example or at least function that does that (I successfully found code that takes position of a MOUSE, and sends click to a MOUSE, but I need that for my HID). What i really need is an example how to simulate click on HID (something like joystick).Second question is a bit more complicated and I can't find a solution. The HID when button is clicked returns data (5-6 bytes). But data returned is immediately printed to the screen (like i typed it on keyboard) and it is followed by CR, however no data is left on clipboard. I don't know how to get that data to my program. Detecting keystrokes using Windows API (something like keylogger), or to make a control (richtextbox) and retrieve data from that control? Thou important notice is that my program is complicated, involves multithreading (cross-thread operations are a mess) and is TIME CRITICAL (as much as it can be on Windows - you get what I mean), so cross-thread access of control will slow me down a lot or even just won't work. Something like this:[code]Even if this problem is solved it still makes it buggy because user should be able to use GUI all the time.

I am trying to copy a table in a database into another database on another connection in VB.NET, using OleDb. If they were on the same connection I would just use SELECT INTO, but they are not. I have two different OleDbConnection and cannot see an easy way to do this.
Right now I am attempting to just copy the database into a DataTable using an OleDbDataAdapter, and then loop through the DataTable and insert every record into the target database one at a time. This obviously takes a ton of time for the large DB I could potentially be dealing with, and I have to deal with escaping strings, null values, etc.
edit - just to make this more clear: I have two OleDbConnection objects, one is linked directly to a local .mdb file on my computer (JET). The other is linked to a database on our servers (SQLOLEDB). I am wanting to do this:
"SELECT * FROM fromDB INTO toDB"
But I can't because fromDB and toDB are on different connections, and the OleDbCommand object is only attached to one. The only way I can see how to do this is to connect to fromDB, copy it into a DataTable, connect to toDB, and copy all of the data in the DataTable row by row into toDB. I was wondering if there is an easier way to do this.

I have a resource file that I include in my shared code library that has all of my re-usable classes in it (all the resources go into their own namespace). Now, what is the best practice regarding resources... should I include them in the same DLL, or should I have a seperate resource DLL and/or are there any benefits from seperating them out into their own file.
