VS 2010 : Write A Program Which Loads A Tiff Image On Picturebox?
Mar 6, 2011I 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).

View 1 RepliesC# - Display An Image In A Datagridview Column Header?
Jul 28, 2009At runtime, I am adding a DataGridView to a windows form. The final column is a DataGridViewImageColumn:
Dim InfoIconColumn As New DataGridViewImageColumn
MyDataGridView.Columns.Insert(MyDataGridView.Columns.Count, InfoIconColumn)
Adding the following code will get my Information Icon (bitmap) to display in each of the column cells but NOT the column header:
Dim InfoIcon As New Bitmap("C:MyPathInfoIcon.bmp")
InfoIconColumn.Image = InfoIcon
Also, it is worth noting that the image displays 'perfectly' in the cells i.e. it is sized correctly to fit the cell.
However, I cannot find a way to add the same image to the column header cell. After some googling I used the following code which placed the image in the header cell but left me with two problems:
The image did not 'auto-size' to the column headercell in the same way it did when added to the column cells. The image was slightly larger and blurred.
By using the _CellPainting event slowed down performance i.e. when hovering over the DataGridView to highlight the selected row the highlighting lagged behind where my mouse was placed.
Here is the code:

Way To Capture Screen Image And Then Read Data (OCR?) From Image
Feb 13, 2010I play a game and in the game you acquire skills which you can display on the screen in a box very similar to a data grid. The grid has 3 columns and X number of rows.Column 1 is the name of the skill, column 2 has a descriptive term like "Beginner" and column has the number of points you have acquired in that skill. So it would look something like this:[code]Remember that it is in a data grid so it has cells like an Excel spreed sheet.The program that I use is able to parse the skill name and the points and save that information outside the game to a n area in the program.My question is, is this possible to do something similar in VB? That is something like, Press a hot key, with will get a screen shot, parse the data and save to a data grid in my VB program.

Error Trying To Read Information From Database
Apr 4, 2012i am new to working with databases, I have done some of my own research and have been adding and regtrieving records without trouble. Now I need to retrieve a specific record based on a selection made by the user. I found that the way to do it is with the WHERE statement and from examples i have seen the code below should be how it is done:[code]The problem I am having is that when i try to run the sub i get the error:Syntax error (missing operator) in query expression 'Show Name = Strictly Hip Hop'.The show name is in the database because that is where the data is retrieved from. All I am trying to do is populate a text box with information from the Host column when the Show Name column is the same as the selected item in the combo box.
