Variable TextBox Name Substitution?

May 20, 2011

have the following code and would like to know how I can substitute the filename (i.e.,test.rtf) with the name of a Textbox. For example, I have several Textboxes that I want to add and associate individual comments to. That is, once the comment is created I will SaveFile with the TextBox name. Each of these Textboxes will have their own comment

Private Sub btnOpenFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOpenFile.Click

SaveFileDialog Substitution Variable?

Jul 30, 2011

I have not tested this, but I am fairly certain it would not work.When my program installs, I want to ensure that the default SaveFile directory is into a directory under the program's directory.For example, if the program installs to C:Program FilesConcept VisionsWorldFileMaker, I want the SaveFile dialog to default to C:Program FilesConcept VisionsWorldFileMakerWorldFiles.I can see in the File System of the setup project, under the property 'DefaultLocation', it's value is:

[ProgramFilesFolder][Manufacturer][ProductName]With Manufacturer = Concept Visions and ProductName = WorldFileMaker, am I correct in assuming this would be C:Program FilesConcept VisionsWorldFileMaker on a default Windows machine?

Below is the code I use to open the SaveFileDialog to save the file. The line in bold is the line I have my question about. How do I get the saveFileDialog1.InitialDirectory = "C:Program FilesConcept VisionsWorldFileMakerWorldFiles" without actually hard-coding it as "C:Program FilesConcept VisionsWorldFileMakerWorldFiles"? I want to use a substitution variable similar to "[ProgramFilesFolder][Manufacturer][ProductName]".

Eventually, I want to learn how to allow the user to install in a folder of choice. If I am correct, I would need such a substitution variable.

Sockets - Flash XMLSocket Substitution App?

Aug 20, 2010

I'm trying to get a (express 2010) app to connect to a socket server (keeping the connection open), how would I go about this? Right now it works using flash XMLsocket, I'm trying to build a new client without flash, using the existing server.Currently I'm just using a simple window displaying messages, and a place to send messages.

It says I'm connected, but it displays no messages, and sent messages appear to have no effect, when I telnet to the server using the same IP and port, I can see messages coming in to me, so i know i can connect to the server. Here is my code:

Imports System.Text
Imports System.Net.Sockets

Literal Substitution - Instantiate Form Objects Using Variables As Literals

Oct 23, 2008

What I need to do is create comboboxes populated with values from a CSV for each class object selected from an Active Directory schema.

So lets say twelve classes are selected, the next form will display the class names in a checkedlistbox and will require twelve comboboxes for associating AD classes to CSV fields. Since the number of AD classes selected will always vary, is there a practical way to code it so that the objects can be instantiated from values stored in a variable?

Other languages support macro substitution, where the variable's value is interpreted as a literal at runtime. Developing in Visual Studio 2005, VB version 8 .netFramework 2.0xxx

Dec 21, 2009

Make A Textbox Choose What To Name A Variable?

Oct 19, 2010

How do I name a variable depending on what is in the textbox?

Like would it look like:
Dim (textbox.text) as string

The reason I want to do this is because the user is gonna click a button to create a task. When the button is pushed, a label is created by the code I already have, the problem is, I want them to be able to click the button more then once and new labels will appear below the one that just was there. By being able to name a variable by what is in the textbox, I will be able to do so many things.

Binding A Textbox's Text Value Setting To A Variable In Configuration File?

Jul 22, 2009

I am binding a textbox's text value setting to my a variable in my configuration file. I only consider the input from this textbox to be valid if it's an integer number bigger than 1. Right now what I was doing is letting the user write whatever he wanted in the box, and I'd only let him save the settings after calling a validation function. The problem seems to be that my binding variable in the Settings class seems to be being updated as soon as the textbox is being edited, and that's a behaviour i'd like to skip. How can I do this?

Loading Multiple Websites With A Different Variable In Each, Based On Textbox Inputs?

Aug 24, 2011

I am a former IT student and have not used VB in a little while but feel it can come in handy to help me complete some tasks at work.I am trying to write a small program which will open a url + a number for each number entered into the textbox. As an example lets say the website is "" and I enter into a textbox 3 values such as "134,325,2112",, and would all open at once.

The purpose of this is at work, we have an employee database and would like to load multiple employees at once (upto 6 at a time) to compare profiles. The issue with doing this manually is we have to fill out the search criteria for each, instead, I would like to load a link with parameters in it already filled out + the employee number we are searching for each number entered into a textbox on a VB form.

2) A start time, for example: strStartTime1 would have the value of 9:45

Retain TextBox Line Breaks In Winforms After Assigning Text To A String Variable?

Oct 3, 2011

I have a WinForms app with a multi-line textbox. This displays and retains (after loading from the DB) line break characters fine. However if I assign the TextBox.Text value to a string variable and then re-assign the variable back to the TextBox.Text property, the line break characters are lost and replaced with a square character (can't past them here as they just paste as a line break!)
