Store In A String The Name Of A Component?
Feb 11, 2009
I want to store in a string the name of a component without using the component itself. I tried the following
Private Sub CmbPriceList_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles CmbPriceList.KeyUp
Dim test As String = sender.GetType.Name
End Sub
The above code returns the type of the component (here it returns 'Combobox'). But I want the name of it.

I found this piece of code which works fine for my input (a string of CSV). The package runs fine, but instead of getting 5 columns of output, I only get 2 columns. I added additional columns in the Script Component and also changed their data types to the suitable ones. The input is 643492,PV STRIP 1X1 UTILITY UP,,67.5,393446. Out of this entire string, I only get 643492 in one column and PV STRIP 1X1 UTILITY UP in another. Rest of the string comes out blank no idea why. I dont know anything about .net and I am new to SQL Server as well.
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
Dim strRow As String
Dim strColSeperator As String

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()
End Sub

I am converting an old Vb6 solution to .net 2.0 in vs2010. I've been working in C# for about 3 years now and .net for 5. I don't recall having this problem in C#, but if I want initialize a readonly collection of DerivedControlFoo Is there a clean way to do it besides creating a sub to do it all off somewhere else? I'd love to be able to do it at the class level at the declaration for readability and simplicity.

I've created a component whose name I'd like to be able to change while editing in the component tray. I've added a Designer action for a name property, but now I'm stuck.
Looking at the property grid, I can see that the name property is parenthesised, indicating that it's not a regular property.

I was wondering how you can copy information (from a webpage, for example) and store it in a string?Also, how would I take only one word of the string if there are spaces between words and I will always be removing the word with the same location in the string (for example, the last word in string).

I need to permanently store a string or maybe a object in my application. And yes, I have tried the application settings (My.Settings).
My.Settings.something = "hi" will save "hi" into something, and when i use msgbox to output the data, it works. The thing is; when I copy my application to somewhere else on my computer it is gone. I guess the settings is saved to some file at the filesystem, and when I move my file it also creates a new settings file. How can I store a string inside my application, and also move the application later on?

I am working on a VB.net winform application which makes extensive us of a mssql database. For the most part (almost exclusively), I have used the Visual Studio dataset for accessing the data. This means that the connection string was created as a program setting, and is saved in the app.config file. The problem that I have, is that I need to move this connection string to the system registry because it has been deemed by the powers that be that a config file is not secure enough.
I think that I can figure out how to access a registry key, and I know that I can save the string to a registry key, but the problem that I am running into is that I don't access the connection key in the code anywhere to easily swap out the registry key for the existing program setting. When VS creates the connection and dataset, where is the connection string referenced? Is there a simple way to swap these out? is it possible even to just reference the registry key in the setting so that I don't have to find where the setting is used and switch it out?

I have a question about static strings and so forth, in an ASP.NET MVC.I need to hold a string(a value), when the user goes through the application.Problem is, I feel like that would be a violation to the MVC. I just need to store a string per user, so it seems like a violation to the MVC separation.

I just want to know what is your suggestion about storing database connection strings in .NET? I am using My.Setting usually, but now I am facing with versioning of my application. When I upgrade my application to higher version the value in My.Setting has been changed, it didn't remain as user has set before, but changed base on my machine's setting. eg. the value in My.Settings Version 1.0.0.0 (User's computer) is 'ABC' When I develop again some new feature on my machine and set its version to 1.0.0.2, of course the connection string in my computer's My.Setting file is different with User's computer's My.Setting. So when I copied my recent updated file to use's computer, then run the application, the application read the new My.Setting file from my computer but not from their computer. the value in My.Settings Version 1.0.0.2 (Developer's computer) is 'DEF' Therefore I have to reset and reset their connection strings onve I updated their application, that's too annoying?

In my application I have many different forms each use 3 different database. And right now I am placing the connection string in each form but when it is need to change I have to change in every form. Now what I want to store all connection string in a vb class and call them in every form. So that if I need to change I can do in that class. I have stored my connection string in database so even I don't want to connect to database again and again. I have some idea in which maybe a public class is used and some how I will call it on other forms.

I have a connection string in my database which I read throughout my VB .Net application. I have another string which is NOT a connection string though. It instead has information about a domain on LDAP. So LDAP string just needs to be stored in the web.config as a string, and also to be retrieved as a string.
