• Mark Benningfield Referencing Text on another form

  How can I make a reference to a textbox on one form to another so that it's text will show up in a textbox on my other form. Example: on Form1 I have textbox1 with information typed in, and on form two, i have textbox2, where i need that information to appear. I just need the reference from that form so I can use it on my other form. Thanks Hi, If you're using Visual Basic 2005 you can access TextBox1 using My .Forms.Form1.TextBox1.Text Best regards, Now that I've use Visual Basic enough, I realized that just doing this: textbox1.text = "Hello" + My.Forms.Form1.Textbox2.Text & " World!" does exactly what i wanted.

• Suresh .M.V best practice when writing to sql server

  I will be writing to a sql database at different points in the program. Is the following going to be ok. during the formload open the connection to the sql server create a sub that writes to the sql server -or- do I have to open the connection, write to the sql server, close the connection every time. Thanks, Nelson I open and close the connection on each read/write. Your main overhead is in the initial connection so when you first connect (I asume to sql2005) it may take a few seconds but after that its lightning fast. Also you may want to think about wrapping all the database functionality into a wrapper to simplify your code elsewhere. You can also then make this wrapper threadsafe therefore allowing ...Show All

• Ultrawhack Dynamic Memory Allocation in Visual Basic

  I am new to Visual Basic, but have had some training in C++. I was working on a program in Visual Basic 2005 where I need to allocate memory to an array dynamically. The array is to be of type ButtonRow, (which is a class I've created for this program). I want the size of this array to equal the total number of rows in a given table. I can figure out how many rows are in the given table, and store that value in a variable (MaxRows). I need to dynamically allocate the ButtonRow array with the size of MaxRows. How do I do that in visual basic Is there a Visual Basic equivalent of the calloc and malloc commands Also, just to give you guys a complete picture, the ButtonRow array is to be a universal array available to all subs within the gi ...Show All

• mcrisf Serious Problem!!! Please HELP!!! Project does not allow changes in code or design

  Hi, I was working at my project (Visual Basic, Visual Studio 2005) and while I was making changes a message box came up asking something about reloading my project. I clicked it.. and since then (i think its from that time) my project doesn't seem to build the changes that I make. For example, I added a form and deleted another, and although the project compiles and runs, the deleted form is still there and the new one doesn't exist. I even added a simple line of code in the form load event of my starting form, to show a messagebox but nothing. I am stuck. Please help. I tried to create a new project and add the forms from the old one but nothing. The forms are empty. Unfortunately it's not that. I have already tried ...Show All

• MikeLR Running EXE without Framework

  So i made a program for this website. But i don't want the users to have to go threw the hassle of having to download .NET Framework just to run it. (Some use this program on Work Computers where they have restrictions on what can be installed) I am using Visual Basic 2005 Express and would like to know how to build to program to include all files needed to run so the other DO NOT have to install .NET Framework.

  In my application controls are created dynamically. I want to know how to write code for an event, for eg. KeyPress event Also how to a call parent form event, for eg. KeyPress event instead of its child control(dynamically created control) KeyPress event (VB 2005) You have two ways to do this. 1.

  I can animate the system tray while my program still do events (for example: while program query database and fill all listboxes, the system tray will have a animated icon) Yes, you can use a timer to control this. You will want to make sure though (possibly through DoEvents() that you long running background work is giving a chance (from time to time) to the timer to do its work and the UI to be drawn. and can I have a timer to do that and at same time do the other operations There is no direct way to do this in the framework instead it would be up to you to replace the image being displayed over and over again to achieve the desired effect. ...Show All
