View 2 RepliesI hoping to find a current and simple way to do this. I'm using VWD Express 2008 and SQL Express 2008.I'm able to get the client's path to the image file using an asp:FileUpload control on the web form.
How do I upload the client's image file and display it in the web form's image control?How do I save it to the sqlserver? The image table is already set up with a "Image" data type column. Can the image be saved to the database as simply as other data types?

Anyone here has an idea where I can get the ports name listed in my PC? [code]I could get COM26 and etc. if any, but that's not what I want. Instead of retrieving COM26, I want USB-SERIAL CH340 or USB-SERIAL CH340 (COM26). How could I do that?

View 2 RepliesI have a form which contains an Image control. What I am trying to do is find a way to adjust an image according to the size of the control and have the image look normal no matter how I adjust the Image control. I want the actual image to fill the Image control completely and not loose any integrity.
View 2 Repliesi am hoping that the possibility to locate all the controls that contain a certain image from the resources, and swap out that image for every control that contained it, will help me narrow down on the simple coding.
something similar to:
for every control that contains backgroundimage=my.resources.imagefound
replace backgroundimage=my.resources.imagereplaced
i tried the above code and it did not work.. lol..

When I run my VB application (as far as I know any application) within Visual Studio I get a bunch of exceptions listed in the Immediate Window. They seem to refer to system files, not the files I generate. They also keep generating as the program processes data. Here is a sample.

View 2 RepliesI managed to create an application that is listed in the 'open with' list only in debug version. Means, when I right click on a file extension and select "open with..." I get the 'choose program' dialog and can browse for my app, nothing impressive. The weird part is, that when I enter the path to the debug version of my program is works, and when doing the same to the release version my app is not even listed, it is simply not shown...
Does anybody know what it needs to make a simple VB.net app be listed here, any fancy debug/release setting?

I have defined a class with multiple constructors so that the underlying interfaces are immutable once the object is instantiated. I would like one of the constructors to be the "default" constructor for when a user types the following in Visual Studio:
var obj = new MyClass( Dim obj As New MyClass(
Currently when I go to instantiate the object, the constructors aren't listed (in Visual Studio IntelliSense) in the order I declared them in my class. Is there a way to mark up my constructors so that their methods appear in a particular order during instantiation in Visual Studio IntelliSense?
I have a UserControl with a property called "Type". This can have any combination of three values, say
View 1 RepliesIn .NET development and don't really know what to use to do some specific actions. I'm also a newbie in AJAX/JavaScript development. I'm using the mvc3.
I'll have to implement a few things :
-rating systems with 5 stars
-classification of items that are listed inside a table. (e.g. : I want all the people that are older than 20)
-searching inside the whole database (e.g. : I want everything that contains the word "tennis", so, it should give me a table with all the people tha play tennis, than a table with the clubs were people play tennis,...).
-a kind of intellisense (e.g. I add a new person inside the database, and for the field "club", I just want to write the first lettes of the club, and then, I would just have to click on the club to fullfil the field).
I've found plenty of websites that give me a library with some of the things that I need. But, I don't know which one I should choose.
I do need something that is as simple as possible, with examples for razor (I'm using VB.net, but it doesn't matter if it's in c#). If possible, having nothing to install could be great (I know that the Jquery scripts that are installed by default are already great).
in terms of code how would i go about getting a single word listed in a listbox to a appear in a rich text box on a single button click?
