View 2 RepliesImage Source From Vb Browser?
Nov 18, 2009I need help with a vb app. Currently it takes a character separated list as input and outputs an sql insert. In the list are urls among other data. What the app currently does is download the source of the first url then load the first jpeg for viewing. At this point I accept, deny, or cancel. If I accept or cancel we move to the next url. If I deny we move to the next jpeg in that source and I'm given the dialog again.
I'm not real familar with VB; I just know that its relatively easy to hack out a solution.. an ugly one in my case. I'm now realizing the way I've done this is too time consuming. What I want is to load the url in a vb browser and then be able to click an image and get its source and move on to the next url. It would also be nice if the images were outlined like with the web developer plugin for firefox. I assume I could just add some css to the soure of each url. Alternatively, I could throw out the vb browser and load each image in some kind of list control.

Bitmap Effects (Firmware 2.0) Change The Source Of An Image In WPF
Sep 2, 2009I 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?

Asp.net - Request() Versus Request.QueryString()?
Jul 5, 2010I have recently started using Request("key") instead of Request.QueryString("key") to access my querystring values. However I have read that:
'Gets the specified object from the System.Web.HttpRequest.Cookies, System.Web.HttpRequest.Form, System.Web.HttpRequest.QueryString, System.Web.HttpRequest.ServerVariables'
Therefore, if I have a querystring key and cookie key which are the same, which value is returned?
How To Link Cell Value At Specific Location In The Datagridview Table To Image Source

In excel VBA, sheets("Sheetname").Cells(rownumber, columnnumber).value is used to get the cell value, but how about code for this case?
