In VB6 I could use an asterisk as a wildcard when searching the object browser. For instance, searching on "c*Report" would find "cFooReport" and "cReport". I can't seem to do the same in VS2008, am I just missing something obvious?
View 1 RepliesI want to make a program that searches for a RGB color and clicks on it, WITHIN the program.
View 2 RepliesEDIT: Note. I should have mentioned I'm not interested in using the .Select, DataRowView, RowFind, I wrote a function to search a datatable for terms in an array. I then return the datatable as a dataset so it can be bound to a DataGridView. Does anyone have any optimization ideas? Since this is a real-time search (every term typed instantly searches) I'd like to make the function as fast as possible. The speed is actually pretty good already but I figured I'd be worth asking you all if there was anything else I could change about it.

View 6 RepliesI am very new to VB.net and for a project I am supposed to do some "outside research" and create a database. The database should consist of items (sports players) who have a number of different values (one set is physical: strength, speed, agility, acceleration) and preferably another (technical ability: ball skill, dribbling, shooting, etc). I want the database to classify these and give each traits such as "Power Shooter" if the shooting stat is upwards of 90, etc. I want to be able to bring up characters through this and also through named searches.

So I have a button that users can click to compound. Obviously its a complicated problem to do well, but in any case, on my path to trying to find the best way to do it, I wanted to create a variable that could be either '=' or '<>' depending on the value of some other variable set elsewhere.Is there a way to do that? Or do I have to switch to Expressions?

I'm new to VB and my book doesn't explain sequential searches very well. I need help with the application I'm creating for school. My application has to allow the user to enter a number and then it will verify if the number is valid by searching through the list of arrays I provided.The question:Create an application that allows the user to enter a charge account number. The application should determine whether the number is valid by comparing it to the numbers in the following list: (see code)The list of numbers should be stored in an array. A sequential search should be used to locate the number entered by the user. If the user enters a number that is in the array, the program should display a message indicating the number is valid. If the user enters a number that is not in the array , the program should display a message indicating the number is invalid.

so my program takes what the user enters into a textbox and searches through the data i have stored and if it matchs one of the peices of data it displays the apropriate data to the user. This all worked fine till i changed the textboxes to be added dynamicly to the form when it is load and i put all textboxes in a collection. So now when the text is sent to the search sub it sends the data over but always returns that it didnt find a match. But if i go into the search sub and just tell it what to search for automaticly it finds it no problem.

View 2 Repliesim creating an array that contains something like this [code]Then i need to make it so when i click on a listview item it searches for the same "Application" name and shows the path.I have everything planned out, but im not sure what i should use to do this.Should i use list(Of string), arraylist or just string(,)?I have no idea of the amount of elements it will contain. I was thinking of using a list so i can use .find without having to make a search function.Anyways, what would be the best/fastest way to do this? Its possible i might have up to 1000 rows in this array, so i want something fastish.
View 13 RepliesI am creating a class that searches a binary file for a specific customer number. I am using a binary search that keeps on slicing the file in half until I find the customer number while is sorted. Once it finds it I am positioning it at the first instance of that Customer number as there can be multiple records with the same Cus Number.
Now here is my question. I now need to loop through this Customers records and do some data base searches. Since I want to make my class as generic as possible what should I pass back to the calling class? An Array with all their records. If I do this I have to loop twice, once in the class and once when it passes the array bac to the original calling class?

I have a windows form which to summarize lets the user open a file containing 32 bit hashes, then search for one of them. The hash is then converted to its string representation. The application is giving the results I would expect but I'd like to make it execute faster than it does now; some files can be pretty big > 100 MB.
I'm doing the file read using a BackgroundWorker object to display progress updates and ensure that the UI is available during the process. But for that i need to add a System.Threading.Sleep(1) instruction in the loop; otherwise the application freezes with big files. And System.Threading.Sleep(1) creates a noticeable lag. Any suggestions on how to make searches fast without freezing the UI? Getting speeds comparable to hex editor programs for example.
I need some guidance on the best way to proceed with searching a file content. I have a large file (see attachment) that is in text form, some of these files could be upto 50 times as big, therefore creating a huge file. These files contain information that is produced from another application and therefore I am unable to change the format of the file.

I am trying to perform a simple bound connection between an Access database and a text box on a form. This is actually Chapter 18 of the "Microsoft Visual Basic 2008" book.I get the same error message when trying to create my own project "MY ADO Form" or the "ADO Form" project supplied from the DVD provided with the book. I am running the 90 Day Trial Version of Visual Studio 2008 with SP1 and Net 3.5 SP1.
My operating system is the 64 bit Version of Vista with all updates.The error when I try to run the application in the debug mode is:"A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll"and as a result no data shows up in the text box from the database and the data selection bar is grayed out in the form. The underlying database "Students Data Set" appears to be fine as I have seen the correct data for the fields "Instructor" and "PhoneNumber" prior to running the program and when connecting with the database.
