I want to get the contents of the active child MDI form, how do you do that? Here's what I did to create a child form.
childForm += 1
If childForm > UBound(childForms) Then
ReDim childForms(childForm)
[Code].....
So say I want to get the text from an active form. How can I get the active form id so I can just do this?
childforms(childform).textbox1.text
Im working with MDI parent/child objects. when closing the child objects i need the child to check to see if it is the last child object before closing. i couldn't find anything on google, maybe im searching for the wrong thing.

View 4 RepliesSeveral years ago I developed a VB.Net 2003 WinForm application using SQL and the DataGrid control. The Datagrid is bound to a SQL dataset in the form load event. Everything work fine.
With the form opened, the user has the ability to size the datagrid control's column width and row height. I want to be able to capture the new row height as sized by the use?
I have a situation where I have several listbox controls on the same asp.net page. They are currently autosized to keep data from truncating. However, I would like to be able to determine the width of the largest listbox and then alter the size of the other listboxes to be the same.
How can I access the size of the listboxes?
I have a request for a util to create a binary file of finite size. For example, the user might want to create a 10KB or 1GB or 400GB file for testing network transfers. I would also like the ability to create multiple files, for example, create 10x 10KB or 5x 1GB or 2x 400GB (so my user would enter qty=5 and size=1GB and have 5x 1GB files in a specific folder).

I'm looking to return a thumbnail image from a full size image stored as varbinary(max) in the database. I'll be using the thumbnails in a gallery-style view, so small size / efficient loading is crucial. I've been using an .ashx to return the full size image into a bound asp.net Image control, with the following code:
Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
Dim conn As New SqlConnection()
[Code]....
I realize it's probably best to address the re-size at the upload, and stored the smaller image as a discrete column. But in the meantime, is it possible to program the handler to re-size the image on the fly? Ideally, I'd be able to pass an additional query string parameter, something like isResized from the image binding, allowing the same handler to be used for both full size and re-sized images.
I am working on a personal vb.net project that will allow me to capture a full-sized image of a given web page. I've been working on this for a few of days and have not found a method that is 100% reliable. Here's what i have tried so far...

Problem: Fails to capture the entire content of the page if part of it is off screen, obscured, or requires scrolling.

View 8 RepliesI have previously used the arguments of a contentsResized event on a Winforms richtextbox to get the new size of my RTB. I am now developing a WinForms app with a custom WPF RichTextBox. My whole reason for doing this is to use the out-of-the-box spellchecker. I need my RichTextBox to expand and collapse vertically as the text is changed. The elementhost will also have to resize to allow the whole RTB to display on-screen.
View 1 RepliesI have a question, I have a combo box, which when changed fills the data grid. Now Wen I change the Tab and come back to same tab again(one containing the combo box)..the value of combo box remains there, however the grid gets empty. I need this data to be maintained till the user selects another value from drop down.
View 1 RepliesTry something along these lines:
TextBox1.Text=(dt1.rows(DataGrid1.CurrentRowIndex).item(0).tostring)
where dt1 is the datatable you're using as the data source and you want the data from the first column of the grid to be shown in the text box.

I have two grids inside a TabItem and in the code-behind I want to be able to add controls to both grids and have all the controls visible at run-time. Currently at run-time the controls added to "Grid3" are not visible while he controls added to "Grid4" are visible.The overlapping grids have the same rows but a different set of columns.I'm trying to do this with two grids so that I can vary the number of controls I can add per row in the code-behind by adding the controls to one of the two grids.Here's the XML:
<Grid Name="TabControlGrid" Margin="20,171,0,70">
<TabControl >
<TabItem Header="Tab1" >[code].....
The controls in the XML are just place holders for the controls I am adding to the grids in the code-behind.

How are crossword puzzle grids made? I have written a program to generate a puzzle, my problem is the GUI part.I ended up using Visual Basic (VB) because I'm more familiar with that language.However, eventually I have to write this in Java. So far the only way I am displaying the results in a grid-like format is using two controls Groupbox with a Label inside it.This way I can put the number to the word's clue in the title line of the Groupbox, and the individual letter in the Label. To make the cell in the grid editable (my goal for a different version of the puzzle), I guess a Textbox would have to replace the Label.The GUI for real online (professional) crossword puzzle grids is much nicer than this.I know there is a way to combine controls to make a customized one. Even if this works in VB, I'm not certain if it can be done in Java, therefore, I really don't want to go that route (unless someone knows how make customized controls in Java). I have searched the net and looked in books on games, VB and Java with no luck.I need something that I can grow dynamically depending on the grid size needed to hold the content.

View 2 RepliesI am trying to use a grid to display datasets. The database that I am using is not on my local machine. I have to dial in and log in to the database. We are using an image database. I was shown by my boss that he uses MSFlexGrid, but it appears that is no longer available on the newer versions of Visual Studio (he is using VB6). I was wondering if there was a way to display these grids without going through the Data Sources?
View 4 RepliesI'm curious what we all are using to display grids of data.I keep falling back to LISTVIEW's in DETAIL mode - they visually look nice to me.

View 1 RepliesI have a bit of a weird issue. We use DevExpress controls to do all our Windows Form development. Anyway, I found a perfect use for the DataRow.SetParentRow/GetParentRow methods in my grid. So I created a DataRelation, added it to the DataSet and bound it as the data source for my grid. The issue is I now find this:On my grid. It seems to be the DataRelation (when I mouse over it the tooltip is the DataRelation name).
View 1 RepliesI have looked at the answers in the forum and some seem dated. I an an old vb2 person and need to move up. I understand sql very well and use complex queries. First test project and trying to add multiple tables to a data grid (Only Form in project).I used the Data wizard to add the Access data base and worked by way through to near the end. The query works in the wizard and returns the correct rows. The error message is "The solution returned by the new query differs from the base query."
During the creation process I selected all the tables. Reading some of the old anwsers I get the inpression that VB 2010 does not handle multiple tables in a datagrid (forum items go back to version 2008).
I am using Visual Basic.Net 2003 with an Access 2000 database.
An integral part of the program that i'm working on is a DataGrid which I am filling from three different queries, based on the user's input. The Grid properties are coded with specific requirements for each of the queries. I have two simple (hopefully) problems.
1) There is no scroll bar on the grid and I can't find a property or event that will allow me to add the Vertical Scroll Bar. How do I do that.
2) The grids contain only four columns each. I want the user to be able to click on a cell and populate four string variables.
