I have a list of names, and what im trying to do is write parts of their names into a combobox. If i press the arrow it should show all the names, but each letter i use should narrow the names to those starting with that letter, until i end up with the name im looking for.
View 7 RepliesI am trying to parse a very large text file for certain strings. The text file is part of a level-making software for an old game I play. The text file basically contains all the information the level designer software needs, but the only important bit is the 'texture information'. Basically what I'm trying to create is a little program that parses the text files and shows the user a list of every texture in that text file. The problem is, the strings denoting textures are not really easy to find, and I can't think of any sensible and fast way to get them...

I tried different methods like FindItemWithText, but it will not work. My challenge is that I have a textbox (txtSok) for the search word, and a new ListView (frmTelefon) that I will populate with the result from my search. The search routine are using data from another ListViewItem on another form (frmOPS).
I would like to have the search done by using the TextChanged on txtSok. My frmOPS have 5 columns, but the search is going to look for items similar to txtSok.Text in column 2. From the result of the search, I will populate frmTelefon with the Add method in three columns (name, address and phonenumber).
I have extended an Entity Framework 4 entity class with a calculated property in a partial class. This member is not available on the client to which the entities are exposed via WCF RIA Services.when using C# appears to be changing the extension of the partial class file from .cs to .shared.cs. I tried this with my VB.Net solution (.vb to .shared.vb) and got a long list of errors. I believe what happened is that the partial class lost its association with the entity on the client - it inherited from object rather than EntityObject.
My best guess is that this is related to the way that VB.Net handles namespaces.Each project has a 'Root Namespace' which is prepended to anything that is defined within a code file. C# has a 'Default Namespace'which is the namespace into which new types are placed by default - via a namespace statement within the file.The partial class is probably having the client namespace prepended to it which puts it into a different namespace than the entity with which it is associated on the server.Is there any means of extending an entity in such a way that those extensions are available on the client via WCF RIA Services and VB.Net?
I am making a project in which if SID 001 is saved .after this SID textbox should display 002 automatically .I am using an Access Database. My code is as shown below:

What I'm attempting to do is create a Form with two Panels:
Left - A autosizing panel with a dock fill richtextbox
Right - A constant size panel with buttons and features for editing the text
Effect desired: When scaling the size of the form you cannot scale smaller than the initial size of the form, but when expanding the panel on the right is anchored to top right while the richtextbox in the left panel will scale infinitely in either height or width dimensions.
I am sure this is likely some simple property of the textbox or the panel, but cannot seem to locate it. I have the panel on the right anchored at constant size, but cannot seem to get the panel left to autoscale on dimension change.
I have a richtextbox that I paste a HL7 msg into and then harvest the message instance manually from the text, what I would like to do is automate the harvest of this integer to automate the selection process.
example of message:
OBX|1|TX|^13971.8498.Report Text||Examination: Right elbow series
OBX|2|TX|^13971.8498.Report Text

View 39 RepliesHere's the weird problem I am trying to solve but cannot get my mind around it. In a text box 1, the user enters 2 or more strings separated by comma. then in text box 2, the user enter 1 or more strings separated by comma. The output then puts the strings from text box 2 between the strings in text box 1

I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?

I am sending some data in a Serialized Structure across a TcpClient Stream to a Client. Now, sometimes the results get through, other times however, it does not. I've noticed this is true when the data I'm sending gets rather large. The server locks up at sending it and can't continue on.I'm sending this structure:
<Serializable()> Public Structure SearchResults
Public Property Results As String
Public Property Search As Boolean
End Structure
When Results gets kind of big (say, 411,000 characters in length), the server fails to send it, I get no error, and I end up timing out completely. If I connect via localhost", I get it instantly, so I know my code works. My problem is I've sent different structures with more data (2 million characters) way faster (nearly instantaneously) across the Internet (not localhost) in less than half a second.

View 4 RepliesSo in my window onLoad method I am pre-populating a grid with values retrieved from a database. Here is the method below for the window load:
Private Sub winMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
''#Load Grid
Dim dt As New DataTable
With dt
[code].....
What happens is, when I press F5 to debug, the program loads, and the grid is still empty, just as it is without a datasource. When I try to step through the code, it actually reaches down to the line that reads
Budgets = BudgetManager.Process.Budget.GetAllBudgets()
and then stepping over this line...the window loads and it doesn't go any further in the method. What the line of code above does is eventually make a execution call of some SQL to a SQLite database, and the code gets to the point at which it calls the execute method, but doesn't even make the query yet. All the objects up until that point in the code are set properly as well (found through debugging and checking locals.)Edit:Exception is this:
"Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.
I have cooked up my first iteration of a code generator which creates the basic Entity models from a SQL Database Schema. Currently, It will scan a SQL Db Schema, and create .vb code files complete with private members and Public property declarations for every User table in the Database. My next step is having it add the basic CRUD procedures as well. Are we mere mortals able to access whatever technology allows the Partial class files created by vs to be hidden/Linked to their "parent" files, such as the Partial Class files for Windows forms or any other designer-generated control? My thinking is that it would be handy to be able to re-generate code files from the database if necessary to reflect changes in the schema, without overwriting any other properties or methods added to a class in addition to those derived from the database. SO I am hoing I can have the Auto-generated output go to a Partial Class file, and then use a regular class file of the same name for the rest of the code. My Concern is the multiplicity of files that might result, so I was hoping it is possible to "tuck them in" to the parent code file in the Class View.
View 7 RepliesI have string which is:
document1.txtdocument2.txtdocument3.txt
What I would like to do is split it so it shows in a listbox as
document1.txt
document2.txt
document3.txt
I have come up with a solution which may work. Its preety over complicated too me but this is the only way I could think of?
What I need help on is a code so that after every ".txt" it will place a "/" so the string will look like this:
document1.txt/document2.txt/document3.txt/
Then I would use this code to split the string:
Dim I3() As String
I3 = I.Split("/")
For g = 0 To I3.Length - 1
ListBox1.Items.Add(I3(g))

how I can select the text in a textbox/richtextbox that is between two designated strings? Like, for instance, lets say "<b>" is the first string, and "</b>" is the second. The text entered in the textbox is "<b>hello world!</b>". How would I get it to programmatically select the "hello world"?
Also, I would like to know of a way to select the text between the two strings and the strings themselves, so that, inputting "Hello <b>world! I'm</b> awesome!", "<b>world! I'm</b>" would be selected.

I guess my question has two parts:
1. My program has to read text out of a text file. I use some HTML tags to preserve the formatting. For example, I might have the line "this is a <b> line </b> of <b> text </b>" where "line" and "text" are bold. How do I make it so the string prints to a RichtextBox, but only "line" and "text" are bold? I would use a RichTextbox.SaveFile method, but the program works by reading a group of richtextboxes in a flowlayoutpanel and appending them to a single text file.
2. How would I extract the text from between two strings? For instance, I have created special tags for use in my program. These tags tell the program where to add controls. Say my string was:
"[IMG= "dog.jpg" /] this is a picture of a dog. [IMG= "cat.jpg"] this is a picture of a cat."
For each occurrence of the string "[IMG=", I would need it to find the corresponding "/]" and extract the text between the two. I could maybe do something with a substring function. I don't know.
I am looking for a control to load text strings into. I want to be able to use different font sizes and perhaps font styles for each text string. I also want to be able to select each text string. I am using a rich text box to obtain the formatting I need but I don't know how to set this up so that I can select each test string independantly. Alternatively I coulg put them into a DataGridView and get rid of the lines but this would look to structured as the cell width is contant for each cell in the DataGridView.
