I am upgrading my program from VB6 to VB2010. In VB6 I am using about 200 pictureboxes loaded at runtime starting with one of each different picture
Private Sub Form_Load()
Image1(0).Top = 2340
Image1(0).Left = Screen.Width - 1300
Image1(0).ZOrder 0
[code]....
What can i use instead of control arrays in VB2010 to get the same functionality as in VB6, or does VB2010 use control arrays?
So I have a Powerpoint presentation. It contains numerous images on it, referred to by image X. (So it's the same image but on multiple pages) These same images on different pages/slides have different width/height attributes associated to them. So even though they're the same image, they may not be the same size.
So there exists a scenario where an image exists on a lot of the slides. I want the ability to replace all of them at the same time (quickly) without having to go through each slide and separately replacing X, one at a time with the new image.
Is this possible? (yes/no)How would this be accomplished? (abstract - high level explanation is only required)
I'm using .NET Framework 2.0 for my application, but I need to get a part from a byte array.Normally I would do this (ByteArray.Take(Amount).ToArray), but Framework 2.0 doesn't have a Take member. Is there a replacement for this?
View 12 RepliesI am trying to make an Image wrapper class or something. The reason for this is that I need to output a bunch of images only, without pictureboxes. I don't want an imagelist, because I need the images along with their associated image properties which an imagelist cannot provide. I ended up with this :

I've been working on a project that requires that I can go around webpages with different proxies, user-agents, and clear cookies. Now after looking all around the net, it looks like there are some solutions for each of these, but I can never get them working. I was wondering if there was a wrapper for this control that fixed all of these problems or even just a different control I could include.

We recently upgraded VS 2005 to VS2010 and converted an application seemingly without any problems. But when deployed to the customer they are getting intermittent errors at seemingly random places in the program which force the application to close and AccessViolationExceptions being logged to the Application Event Log.
The customer's site is a multi user environment with the application hosted on a server and users running the app via RDP. We get two errors in the event log:

I am working on upgrading an old Access 2000 database to VB .NET (2010). There is one form that I am having trouble figuring out how to build so that it works similarly to the Access form. In Access, there is a header, detail and footer for this form. The objects in the detail section only need to be created once and Access will "copy" them for each record in the database and fill in the appropriate information (the form objects include buttons, textboxes, comboboxes, etc.).
How can I do this in VB .NET? Each different area that is chosen will have a different number of sections. I've thought about using a GroupBox, but I'm not sure how to make that work.

I am using the MSComm controll. I have duplicated all the settings from the older program.
The application reads information similar to a DXF file. For purposes of discussion, the data consists of lines, those lines have endpoints, x1,y1,x2,y2. Within the file those lines create "paths", in other words, they are connected. There can be many separate paths within a single file. However in the original file, the geometry is not in any particular order, the paths are not indicated.
View 3 RepliesI use VB in Visual Studio 2008 Pro. I've created a few solutions using the Crystal Reports tools. I found them easy to work with & easy to do things, (export to different formats, refresh reports, write an automated service that ran & saved reports, etc...)Is CR in VB 2010? If so - which version of VS 2010 do you need to buy to get it?OR - is the reporting services in VS a suitable replacement? Is there a viewer / preview like the CR tools? Can you create a standalone app to refresh reports & export them to different formats? Which version of VS 2010 would I need to purchase to get these?At home - I use Win 7 media centre (a fantastic piece of software). Are there any development 'goodies' in Visual Basic 2010 for Win 7 Media Centre?

I have to update and old VB project made with Visual Studio 2005 that uses Crystal Reports to Visual Studio 2010. I've installed the Crystal Reports plugin for VS 2010. I can compile the program under VS 2010 but when I run it and try to generate a report I get many errors popping up from the Crystal Reports Viewer. When I compile and run the project in Visual Studio 2005 (with the old Crystal Reports plugin that comes with it) everything works fine.
The problem is caused by SQL Expressions that are SELECT statements that are not enclosed in parenthesis. This is a problem because there are ~250 SQL Expressions like that in the report file (and it's not the only report with this problem). When I look at the .rpt file in Crystal Reports 10 and use Database -> Show SQL Query the SQL Expressions have parenthesis around them despite there being no parenthesis around these statements in the SQL Expression Editor. When I do the same in Crystal Reports 2008 the SQL Expressions don't have the parenthesis included.
Is there a way to make Crystal Reports 2008 or the plugin in for VS 2010 automatically include the parenthesis around SQL expressions, or was this feature removed? If it was removed, is there anyway to enclose the SQL expressions in parenthesis other than editing each one manually?
and i need to convert the image into a text.now anyone thinking that i can just use ocr is unfortunatly wrong i have tried about 5 of them and they dont work because the text in the image is to small for it to recognise it.so i need to search the above image for a smaller image such as this.so by doing this if i get a result saying true then i will be able to go from be there and convert to text.now i know of two way to search an image for a smaller image. first is by going by pixel search and well i can get that to work but it is to slow.the second method is to convert the image to a byte array(beig an image it will be a 2d byte array) and convert the other image to a byte array and then compare.

I need to dynamically create some sort of 'table' on my form. It should look like:
PIC1 INTEGER1 TIME1
PIC2 INTEGER2 TIME2
PIC3 INTEGER3 TIME3
On top of that it should look like a table and have gridlines between the 'cells' containing the picture/data, which makes it even more difficult for me. Before, control arrays were quite simple in VB6, but I've been searching for 1,5 hours now and I can't figure out how to do this in VB.NET 2010. Any idea how to tackle this the most efficiently?
I have added controls to the form using a control array.. However, when I re-run it they stay and more appear. How do I get rid of the first set?
