i have a stored image in my database. i want it to be displayed in picturebox. here is my code
Private Sub ListView1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListView1.SelectedIndexChanged
Dim index As ListView.SelectedIndexCollection = ListView1.SelectedIndices

I want to design visual match the pairs. There will be two columns. The left column will have images and the right one will have word labels. User have to drag image over the correct label.
Since the form size is small, images will have to be smaller (thumbnails). So there should also be image enlargement when user hovers mouse over the image. The user should also still be able to do a basic drag-and-drop of the image.
I am trying to write a program which loads a tiff image on picturebox. Then the user clicks somewhere on loaded image to set the starting x,y coordinates and clicks again to set the ending x,y point. Then clicks the run button and the starting and ending x,y points are written on label.
Just to test the program a loaded a tiff image that has a dimension of 75x75 pixels. When I click upperleft and downright corners of the image, the program outputs the coordinates as starting x,y as (103,89) and ending points as (170,157). The program outputs wrong coordinates becayse the image has 75 rows and 75 colums only. To me, it should have outputted starting point as (0,0) and ending points as (75,75).
Public Class Form1
Dim StartX, StartY, EndX, EndY As Int16
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I have most of the coding done, but i don't know how to code my hangman program so that when you enter a wrong letter, a picturebox image would appear eachtime. Also i want to put a limit on the amout of guesses you can have. If possible, i would also like a listbox with the letters that you have guessed wrong stored in it.
Here is my code so far:
Imports System.IO

View 6 RepliesI'm looking for the easiest way to bind data from a SqlDataSource to textboxes dropped in Visual Studio 2008.For example, I have 4 textboxes currently that have Address, City, State, Zip.I also have a SqlDataSource on the page fetching the ID of the record and selecting those 4 fields based on ID. How am I able to quickly bind each box to those particular fields selected? I would think this would be really straight forward - but seems it's not. Seems like the answer is funneled towards having to create a GridView or some type of control.

View 1 RepliesI am trying to bind data from a text box on my form to a field in my database table. First of all I have created a DataSet, BindingSource and Table Adapter in the forms Design view, but I am having from there. Under the properties of each text box I have set the DataBindings (Text) to the field in the table under the forms instance and DataSet rather than the Projects Data Sources. I am very rusty at Visual Studio 2005 and that is all I have to work with.
View 2 RepliesFirst I have 2 tables, for example Customer and Orders, and in the database there is a foreign key relation between both. For clarity Orders have a foreign key field to the primary key of Customers, thus Customer is the parent and Orders is the child table of the relation. My application is a Windows Form application, and I add a dataset to the project, in which I drop the 2 tables, and the relations between the 2 tables is automatic added. Now I will om a form loop through the Orders table (witch is the Child table) and show in a textbox some fields of the Orders table and also the Name field of the related record of the customers table. Regarding binding a textbox fo a Orders field I do it this way,
Dim myDs As New DataSet1
Dim myAdpCustomer As New DataSet1TableAdapters.CustomerTableAdapter
Dim myAdpOrders As New DataSet1TableAdapters.OrdersTableAdapter
myAdpCustomer.Fill(myDs.Customers)
myAdpOrders.Fill(myDs.Orders)
Dim myBindingSource As New BindingSource
myBindingSource.DataSource = myDs.Orders
myBindingNavigator.BindingSource = myBindingSource
TextBox1.DataBindings.Add("Text", myBindingSource, myDs.Orders.OrderIDColumn.ColumnName)
But now I can't find how to bind a textbox to a field of the Customers table witch is the Parent table of the relation.

I have a Picturebox and a two Buttons on my Form. On click of one of the buttons I want to change the image in the picture box at runtime.
This works fine when I give the location of the image (the full path ) on my computer - but then of course it will not work if I use the solution on a different computer .
So I have made a folder named "Pics" inside my application and added two images into it.
How do I get to this local folder in the following code?
Picturebox1.image = system.drawing.image.fromfile (??? )
instead of the usual,
Picturebox1.image = system.drawing.image.fromfile ("C:UsersMyName My PicturesMyPicture.jpg" )
