Bitmap Effects (Firmware 2.0) Change The Source Of An Image In WPF

Sep 2, 2009

I think that changing from WinForms to WPF just because the blur effect is easier to do in WPF is the stupiest thing i can do right now it took me time to understand how the windows form application works i dont even how change the source of an image in WPF so here we are again. how to blur a speciefied image using CODE ONLY ?

See what im trying to do:

1. Imagine that you turn on your pc. takes some time to load.
2. Finally for the first time you are on the desktop.
3. Before you do something after every icon is loaded my program
takes a picture of the desktop and blurs it.
4. then it runs fullscreen showing the desktop behind as blurred and
not giving you access to the desktop.
5. a login/register border pops up
6. if you login the program closes if you dont it stays there
waiting for you to login or register.

I wont use it that way im planning to do it on the startup of my program only blur the window not the screen (i mean the content of my window) untill you login or register then it clears again. What i need to learn:

1. How to take a screenshot of my program (only yhe content of the window) [Progress: 1% (cause i know how to take a screenshot of the desktop)]

2. How to blur that image [Progress: 100%]

No need for third party programs or dlls i mean isnt there a default function in vb.net the stupiest way to do it?

Select Case & Combo Box Value?

Jan 26, 2009

I am using visual basic in VS 2008 and trying to learn how to assign a value to a word in a combo box using case select, this is my first attempt at programing and i just can't work out what to do next. So far i have two combo boxes a label and a button, i want the word, first to = 11, second = 9, third =7, fourth = 5. All it is doing at the moment is adding the list index value and displaying that total in the label. I want it to display for eg: if (first=11) and (second=9) are selected a total of 20 in the label,and so on for what ever combination is selected.

Use Combo Box In Select Case Statement?

Nov 21, 2009

I am a noob and I am trying to make a simple resistance calculator for practice. I use text boxes to let the user input the current and voltage, and then a combo box for the units and then a list box to display the results. For some reason no matter which units I select it doesn't convert at all. For example 1/2 will always show up as 0.5 in the list box no matter which units are selected from the combo box. Here is my code.....I know that there is more cases but I only put one to see if it

Public Class Form1
Dim unitsA As String

Make The User To Be Able To Select A State From A Combo Box?

Feb 8, 2009

I'm setting up a program where I would like the user to be able to select a state from a combo box. I can not figure out how to allow to select the abbreviation from the drop down list and also allow them to type a letter and it will select the state from the state or just allow them to type the full abbreviation that would match what is already in the list. It is supposed to be in the drop down list style. I would also like to confirm that the user has chosen a state before allowing them to click a submit button but I'm not sure how to go about confirming it.

Combo Box Event To Select Certain Data From An Access Database?

Nov 30, 2010

I am using VB 2008 Express to connect to an Access 2007 database. I have a combo box that is populated by the database. When I used the Access report VBA, I used the AfterUpdate() event to calculate a sum and place the results in a text box. I need to know how to do the same operation in VB 2008 Express using the SelectedIndexChanged event of the combo box.

The combo box is called "cboYearMonth" and is populated by my database, this is working correctly.

The text box that I want the calculated results to appear in is called "ExactPagesTextbox"

I have a query in Access called "JobTypeExact_Query" that contains all the pages that I need. What I need to do is calculate the total number of "Pages" limited to the YEARMONTH selected in the combo box. YEARMONTH is a value in every record in this query.

Application That Allows User To Select Or Enter Into A Combo Box Number Of Days A Person Will Work

Oct 28, 2009

Create an application that allows the user to select or enter into a combo box the number of days a person will work, and calculates the total amount of pay she will receive over that period of time. Salary is one penny the first day, two pennies the second day, four pennies the third say, and continuing to double each day.

The combo box must list the following items: 30, 180, 365, and 1000. Must be the default drop down box. Use a validating event procedure on the combo box.

The program should go through a loop once for each day, doubling the number of pennies with each iteration of the loop. You will need a running totl of the number of pennies that you add to with each iteration. To calculate the total amount of pay, multiply the total number of pennies by .01 and show the result in currency format.
