View 5 RepliesI have a program where I don't want the UI going white and unusable while processing some SQL queries. So what I did was set the two long queries into a Thread and put a ProgressBar in Marquee mode just to indicate something is happening.
My issue is that I need certain Buttons enabled and disabled at certain times, so the only way to do this is to, after the SQL statements are run, do the proper testing to see which Buttons need to be Enabled. However, I obviously can't put these after the Thread execution or it happens immediately after the .Start() command. So, they need to go in the thread. But, I'm not understanding exactly how to go about changing the state of the Buttons from a different thread. Here is my

Is there a way one can edit sound, say for example you have an mp3 sound it is 12sec long, but you want to fit it into 10sec. is there a way one can write a code that automatically adjust the sound so that it only play faster and save it as mp3 again? I am not talking about existing programs to do it. rather a standalone app?
View 1 RepliesI am creating an VB 2008 application which uses 2 connections strings in according in which computer is running (my test machine, and the production server). How should i manage the connection string in order not to change manually the connections string which are many inside the code??
I have read that you can read them from an external line, or if you put both connection strings in an external file, according in which machine the program is running can actually the correct string?
I would like for my program to navigate via textbox1.text with multiple lines and multiple url links inside of it. I know how to make the webbrowser1.navigate via textbox1.text with multiple lines, however I want my webbrowser to navigate to each url every 1-1.5 seconds once button1 is clicked. Yes, my webbrowser1 will navigate to the specified urls via the textbox1.text (multilines) with a button click, but I need the webbrowser1 to navigate in a order sequence from top to bottom of Textbox1.text (multiplelines) every 1 second. Here is the current code that I have to navigate via multilined textbox1.text control in order sequence:

View 2 Repliesim working on a small application that lets you input a phone number with "-" hyphens, and then copy that number to a label control minus the hyphens. So for instance 111-234-567 would become 111234567, i have accomplished this using the string.
replace command, however i was wandering if it would be possible to iterate through the string with a for next loop looking for the hyphens and then removing them with the string.

I'm familiar with creating tables, updating, deleting, etc. etc. using a seperate VB program and a MS Access database.
However, I would like to know how I can start manipulating reports.
For example:

The user selects a radiobutton to determine how the report is ordered (ascending by what field)

I have a program that will register you for a certain website using textboxes and stuff but I have an invisible web browser and it just enters the text into the right spots and clicks the button.I was told that I can get rid of the web browser and do the whole thing faster and easier using "HttpWebRequest and HttpWebResponse".
View 2 RepliesI understand that there are several ways of Inserting, Updating and Deleting records in a database such as DataAdapters, DataSets, TableAdapters, SqlCommandBuilders, Parameterized SqlCommands, StoredProcedures, etc, etc,etc. According to David Sceppa Sprocs are the most preferred. Ok, I go with him on this one (who am I to challenge him anyway?).
My question is, apart from Sprocs, which of these options is the BEST for a large commercial database application and why, taking performance into account? What are the benefits and drawbacks of each option?
I have eight text boxes each can have any numerical value only consisting of the numbers 1-8 up to eight digits each. No 0's or 9's.I am using a timer to loop through the sequences of text boxes at a given rate. This is already configured.Now here's the hard part so bare with me.I need to output the first value of a text box, wait some time then output it's counter letter (below the number on the keyboard), go to the next text box and repeat.

I'm looking for a SIMPLE and easy to use, very basic, image editing library. All I need to do is check the size of jpeg and png files and rotate them by multiples of 90°.I can develop my app in VB.NET or preferably VB5 and I'm not using any other library.
I tried the Advanced Image Library (based on Free Image Library), but I can't get the dll to correctly register and I'm afraid that I will also have problems when distributing the application.Is there something simpler? If it's not free it's fine, as long as the cost is reasonable.
I wanted to know if it's possible to remove a paticular item in my collection and then add it back at a certain location? e.g. say I use RemoveAt and remove the first item in the colleciton; after, I want to add it back at a particular location (index)? Maybe this isn't possible with this type or any other type collection?

I'm developing my first SQL Server database app (for 30+ users) and could REALLY use some advice particularly because the app's design is pretty complex so please bear with the long explanation. My app eventually will display an always (hopefully) up to date list of files (and some related metadata) for a variety of purposes (open file, modify file's metadata, etc). The users deal with (open files, modify metadata, etc) dozens if not hundreds of files everyday so developing an app that making it all super quick and easy would really save company time in our environment over the course of a year.
The list is always enormous so my plan at the moment is to never close the app once it's running.The app will have schemes (TBD) for updating the list (modified data, new files & deleted files).It takes approx 45-60 seconds to load all the data which would make my app unusable if I were to allow the user to close the app.The design gets complicated because the list is a merging of two folder structures that share
some relative folder structures and files. The main list comes from a document management system (DMS) and the secondary list comes from a specific local folder structure (e.g. C drive). As with many DMSs, the user cannot modify documents directly in that system.

First thing I should point out, i have looked all over, especially on DIC for examples, have found some, but none that i could get to work for me. I made a program that inserts data into a DB and then on another form it shows a gridview with the data from the DB. My first issue is im not sure how to insert items into the DB when the DB has an auto number field. I have seen on the internet to just not specify that field and let the DB handle it but its not working for me. This is what i have for that part:
