Set The Viewable Area To A Smaller Screen Area?
Jun 11, 2012Trying to set the viewable area to a smaller screen area and have it cycle through as the person moves using collision detection to move the backgroudn image. Here is the start but its off to a bad start so far.
Public Class Form1
Dim Mapx As Integer = 600
Dim Mapy As Integer = 2000
[code]....
Basically the forum size is set to 600x2000 but the client should only allow you to view 600x600. I want it to add +1 once you "collide with a invisable box I'll add and this will redraw the screen.

View 1 RepliesHide The True Value Of Datagridview Cell?
Oct 5, 2009if there is a property of datagridview that will automatically formats the value of each cell but it will go back into original value before the user edits its data. This is only applicable for double datatype.
example. the value of the cell is 12908.21232311. But the datagrid will show only 12908.2123. And when the user edits the cell, the 12908.2123 will go back to its original form 12908.21232311. And when the user changed the value of 12908.21232311 into 12908.44444444, it will format again into 4 decimal places which is 12908.4444

View 3 RepliesHide Buttons In Select Rows With ButtonColumn In DataGridView?
May 6, 2009Is it possible to add a button column to a datagridview and then remove a select group of these from rows without removing the rows themselves? That is, I want the ability to hide or remove these buttons in certain rows after certain actions have occured. I realized that I could simply delete the rows with these buttons, but I want to keep the data in these rows visible without the user thinking they have to use the buttons. I am assuming that I can also disable the buton in the desired rows as well.
View 2 RepliesShow / Hide Datagridview Rows By Setting Trackbar Value
Feb 2, 2012I need a help with showing/hiding rows in datagridview by setting the trackbar value. The below example works if there are not too much rows. If there are greater number of rows then after you change a value of trackbar you must wait for a few seconds for the datagridview to redraw and only then you can use trackbar again.Apparently I must use multithreading to achieve what I want: when I use trackbar, datagridview starts to redraw, but if I use trackbar again before datagridview finishes redrawing, it immediately stops redrawing according to previous trackbar value and starts to redraw from the beginning according to current trackbar value. That way trackbar will never be frozzen (stuck, unusable...).I tried with backgroundworker but got error "Cross-thread operation not valid: Control '' accessed from a thread other than the thread it was created on." I have old and slow computer. If you have new and fast computer maybe you wont experience what I'm describing here so try to increase number of added rows in line 'For i As Integer = 1 To 5000' (I added 5000 rows here) - and if you have even older and slower computer than you will have to decrease this value or you will have to wait to long after you drag the thumb in trackbar.

Asp.net - After Resizing White Image Gets Gray Border?
Jul 25, 2011i was searching google for some kind solution and i found one, i tried to implement it in my code but it doesn't work. The problem is that after resizing white images they gets gray border.Here is the link of soloution i found:It says:
This problem is occuring because you are interpolating your image data to a new size, but along the edges there are no pixels to interpolate and .NET uses black pixels for these edges by default. To fix this you need to use an ImageAttributes class in your DrawImage call....

May 5, 2012I'm curious if it is possible to hide a group of text boxes from view in a form until a particular condition is met, and to have a custom set of text boxes for that condition. To give an example; I want radio buttons offering choices for a manner of searching records, the user selects one and then a specific set of text boxes are displayed for the user to utilize, if a different option is chosen a different set of text boxes will be shown. Is this something that can be done?
