I was thinking a list box? but I'm not all too sure on how to use one. I'd like the user to be able to scroll down through the list OR use a search. How could I search the list?(Id use a textbox as what to search for and a button to search the list.)
Couldn't think of a better title.(Background on the problem/me)Okay, so, first question/post here, so hi. Now that that's done with, the information pertinent to my problem. I'm fairly new to VB (and programming as well, aside from screwing around with C++ and learning assembler(well, attempting is the better word) god knows how many years ago), and have only seriously been programming for about under half a year, and my skill level is about at that stage. Only been using VB.Net, nothing older. Depending on the time of day and if I'm home or at school, I fluxuate between VB express and Vis Studio 08. Umm, this program I'm having trouble with was on a test that I took yesterday (took the problem home with me cause I really wanted to figure out what was wrong with it).
The stipulations of the test were:
No For->Each Loops
No using Built-In Sorting or Searching Functions

I'm developing an app for WP7 and Win7 that will get info extracted directly from particular websites. The app will download the HTML source and parse through it to find the required strings. The strings may not have tags. note multiple instances of the string needs to be found. I've tried a few very rudimentary ways, and although they work, they are extremely slow.
View 4 RepliesI'm working on a .Net Windows application. All the controls arrange fine, but when the user specifies their Windows display text to be larger than the Windows 7 default of 'Smaller', the controls get moved around on the form and makes it unusable.
Is there a way to lock down those controls no matter what the display text setting is at?
How do I display a large amount of fixed text (about 400 words) in a form. I also need to have scroll down bars.[code]...
View 1 RepliesWhat I want to do is display large amounts of text and a few pictures, ideally with hyperlinks between the pages. A lot like wikipedia really, lots of similarly arranged pages, text in categories with in-line hyperlinks and the occasional picture to illustrate a point.But not online, integrated as part of a larger app.
How would it be best to go about doing that? The display method is sortof dictated by the storage method. My thoughts were:
Lots and lots of labels stored in an Access database
Straight HTML as if it were a webpage embedded in an iFrame or something
Labels populated from XML files?
Program the whole lot in Flash or something else (A language I can't speak)
This is only a mockup for demonstration purposes so the priority is user-friendlyness and ease of programming rather than storage concerns or good programming form.
I am trying to put colored text into a list box. I use the following

I am new to VB.Net, but I can tell you so far I love programming. That said, I'm building a tool basically to parse and display simple plain text log files. I'm hitting one stumbling block that really has me frustrated.
Other tools are able to load huge log files (500MB even) in a number of seconds. My tool, basically hangs loading a file that is maybe 5MB.
I'm using the MyString = StreamReader.ReadToEnd to read the contents into a string, and then RichTextBox1.Text = MyString to display the contents. That said, I really want to display the contents in a datagrid, but there has to be a better way of doing this?
How can I get my application to load larger files and display them faster? What am I doing wrong?
I'm using this code to search a msacces db and display the data in a listview.The Search is fired after the text_changed event of a textbox. So each character is a search and also each backspace(here's where the real pain is) it will search. When I use backspace its very very slow! When I use 100 or even a 1000 records no problem but this db has 10.000 + records.Whitch event can I use to solve this problem or how can I adjust the code for faster search? ALs o when I test on a windows7 system, dualcore, 2gb memory, when I press a key it will take time before I see the character in the textboxs? Its a new system and only runs this program.I use a texbox to enter for example an artist name and a combobox where the user can choose to search on artis, title, genre etc. [code]

I'm working in a program that need to do the following.An airplane has 15 rows (1-15), with six seats (A, B, C, D, E, F) in each row. I need to write a program to display the seating chart in a list box, when the person clicks on the desired row in the list box, the row number and the status of the seats in the row are displayed in seven read-Only list boxes.Now, I know how to create a listbox and the make the text boxes, my problem is how to display what is in one row into 7 text boxes.Then the person click on any of the text boxes a second form with 4 radio buttons is poping up. This form will have the status of the seats, (Unoccupied, Low Carb Food, Vegetarian and Regular) if any of these is selected will change the status of the seat at the listbox and the text box..Should I use arrays to fill up the listbox and redim when update is require?
View 2 RepliesI have a 133 Mb file which contains almost a million records. Currently, a user loads this file into KEdit (a great editor for working with large files) and changes occurrences of a dollar sign $ to blank and takes negative numbers represented as such with parentheses and changes that to a negative sign. That is, (5000.23) would become -5000.23. So the leading ( becomes a - and the trailing ) becomes a blank. I believe the only occurrences of ( and ) are around the numbers I want to change, so I don't have to worry about changing something that should have been left alone. Using VB.NET in Visual Studio 2008, is there a "painless" way to do this other than reading the file one record at a time and searching/replacing and writing the record out? While not really painful, I am worried about how long that will take (to run, not to code ). Is that a valid concern?
My long range goal is to automate many of the routine file preparation tasks my users do. We get an input file from 15 clients. The file can be in any format the client has chosen to give us, and it is our burden to reformat any errant fields into an acceptable format for insertion into our database.
Build a small application that fills a collection (list) with 10 sequential numbers, and then prints the collection(list) in reverse order, skipping every other member, until the entire collection has been displayed. For example, if the collection contained the numbers 1 through 10, they would print as:
10, 8, 6, 4, 2, 9, 7, 5, 3, 1 The print out should be in that order no matter what sequential numbers are in the collection (list). If it were 21 through 30, output would be 30,28,26,24,22,29,27,25,23,21 and so forth.
Note: you must use a collection - do not write down the numbers directly to produce the output. Loops should be employed but the loop control variable should be used as an index or subscript number. Your code should work even if I change the list of sequential numbers to something else. Remember that indexes count from 0 first -- the first item in a collection has index 0, the second item in a collection has index 1, and so forth.
I've got the first part of the problem, getting the numbers in the list box, done with no problem. It's the second part I am struggling with. I cannot get the numbers (I am using 1-10) from the list box to display in reverse order in an adjacent text box.[code]...
I have a list box with information that needs to be displayed in a text box. Each of the lines in the list box has 2 types of information-Name and setup data. When I click on the line I need only the setup data to be displayed in a text box. This data on all lines begins at the 42 column. I can display the information using SelectedIndexChanged but the entire line is displayed. In other words I need to display only the data from the 42 column to the end of the selected line.

My program creates a array of numbers as entered by a user and then finally adds them up. The form should be able to display the numbers typed in by the user. I know how to put one of these numbers into separate labels and could display each number that way but I wanted to know if there is a simple way to display the string that is created as a list in perhaps a read only text box or similar?
