I am going to create a windows form and add a push button (pretty simple right?) I want the push button to randomly cycle through about 10 pictures and display the randomly selected picture.
A few problems I am facing, 1) I do not know how to do do "randomization" in VB.Net and 2) I do not know how VB.Net would handle displaying an image, would it display on the form i am building or would it display in the default photo viewer for Windows?
I want to load a picture using a browse button.

The browse button appears, allowing me to search for a file, but when i select the file and click open, nothing happens.
I am looking for a way to take an image from an OpenFileDialog and save it into a database as an Image, then use the Image data from the database to display it in a PictureBox and set it in an image list.

View 2 RepliesI am currently working on a family project which is based on "Who Wants To Be A Millionaire?" show. There is a huge diffrence between the show and my project. My project is a christmas edition and the goal is not to get money or something, since I will not add it... Erhmm... Let me get to the point. I have already designed a layout and scripted some things. I have about thirty questions but I do not want them to always spawn in the same array, if you know what I mean. I want the program to randomly choose one of those thirty questions and NEVER choose the same question in the same program run. By the way, there are four options on my project: A, B, C and D. I have got everything, I just need a code.

Possible Duplicate: Which language should I pick up: VB.Net or C# I'm trying to make a descision on learning VB.NET or C# as my first .NET language. I'm aware that bith languages can achieve the same things since both ultimately use the .NET framework. I'm also aware that C# has a similar syntax to both Java and C/C++, so I definitely see the benefits with this.
But how about the future of VB.NET? Will it be maintained in the years to come?I do know a bit of python, so would that make C# easier to learn?

My users need to browse to select a file and then save it to a different location. Here's my code I've got so far - it incorporates the OpenFileDialog to open the file and the SaveFileDialog to save the file. When the code goes into the OpenFileDialog portion, it works great....the initial directory is set to "C:" This is where the user will select the file they want to save to another location.

View 5 RepliesThis is my first post on dreamInCode, Is it possible to browse and select a file on a server share, but I need it to return the UNC path. e.g. if I select F:\sharename\filename.txt, it will work out the share path on the PC and show the actual Path.\\servername\sharegroupName\sharename\filename.txt
The reason for this is that some users have different share drive letters.

I'm trying to put a filter in the OpenFileDialog that makes it only show files with the extensions .REB and .MRG.
This is what I have but it isn't working: OpenFileDialog1.Filter = "MRG and REB Files (*.MRG;*.REB)|*.MRG;*.REB"

ok, So I can call on the open file Dialog so it can be used. The problem comes when I want to put it to actual use. The idea is that the user pics an image from there "directory" and then it displays in an image box (which is already there) so, how would I use the open file dialog to locate the image and then display it in the image box?

Which language, VB.Net or C# is the best language to choose for development right now? Needing users to have the .Net framework is something that I see as a drawback to Vb.NET, but what are the pro's and con's of each language? What can be achieved with one but not the other?
View 1 RepliesIs there a standard .NET control for what I call "a two pane picker", or do I have to code it by hand?
Two pane picker:
The left pane has a list of items. The user can pick items from the left pane to put them in the right pane using buttons between the two panes. Picked items in the right pane can be reordered with buttons.
An example of the "two pane picker" can be found by right clicking the Quick Access toolbar in Word 2007 and clicking "Customize Quick Access Toolbar..."

I have written a program in vb.net 2008 (using .net 3.5). It's a decent size program. One part of this program is to access an online database and encrypt/decrypt files. To access db I use a hardcoded password. To encrypt/decrypt files I used a hardcoded key. No matter what I do I would need to hardcode one of the two things at least. For example: even if I store database password in an encrypted file I would need to hardcode key to decrypt it. Or vice versa. So after doing some thinking I figured that I need to obfuscate my code so that at least these hardcoded elements/values wont be visible easily. Infact to test, I used a program to disassemble my program. And to my amazement, it showed me every line of code in my program. I felt as if my entire code is pasted in my exe.
Thus I need to obfuscate my code. See I do not need too advanced settings. My program is not among the top shareware programs or super popular that I need very high security. But I need enough security so that my basic code, variables and sensitive information (password etc) is not visible. Please help me choose a good obfuscator which will do the job. It should not be too tedious to use and should be sufficient for me. Plus it should be trusted and secure. I mean I don't want my application to crash or be unstable after I obfuscate it. I have downloaded trial of .net reactor from Ezriz and it seems to be fine. What do you guys suggest? I cannot affort something over $200.
I'm making a program that starts opens different folders on the user's PC. However, I want to be able to have a program in that folder selected. So, whenever the user opens up the folder after clicking a button on my form, I want one file in that folder to be pre-selected.

Or rather this one:

This is not a question about whether to type cast the Id column to Integer by using .Field(Of Integer), CType, CInt, DirectCast or whatever but generally about whether or not you choose Linq over forloops as the subject implies.
For those who are interested: I ran some iterations with both versions which resulted in the following performance graph:
The vertical axis shows the milliseconds it took the code to convert the rows' ids into a generic list with the number of rows shown on the horizontal axis. The blue line resulted from the imperative approach (forloop), the red line from the declarative code (linq).
