I'm thinking of porting my application from VB.net to the C# based MONO project, so it can run on both Windows and Mac. However, I am in need of a Mac-friendly alternative to WPF. It has to have very similar functionality. QML (by QT) is not a viable option, as it costs far too much money for us.
View 3 RepliesI wish to use common CRC logic in a VB.NET or C# application as well as on a C/Linux application. I have one C/Linux application that interacts with a webservice (written in C#) and also a web application (written in VB.NET). For some data, I want to add a CRC to the data itself (say a file) from the .NET side and check for the integrity of the data (checking the CRC) on the client - and also vice-versa.
View 2 RepliesI have a interesting problem: Where I work we've built a home-grown ERP system in VB6 that we are slowly moving over into vb.net. There are some projects have are in .net: we have a hand-held C# project that uses a web service to talk to our database, I've built some reporting screens using Crystal and some smaller maintenance screens.
Well as we have been plotting the conversion out, we want to have a way to separate our business logic and UI so that the UI can be a win/web form or a Smart Device project. Is this even possible? I try to reference the DLL in a test I have and it gives me this error when trying to debug using a emulator Deployment and/or registration failed with error: 0x8973190e. Error writing file '%csidl_program_files%smartdeviceproject1system.windows.forms.dll'. Error 0x80070070: There is not enough space on the disk.
am devoloping a simple program in vb.net but i wanna do it a cross platform almost (windows & linux) or if there is a vb.net to C++ code converter
View 2 RepliesFor sometime now whenever I am in need of formatted text I have been using RichTextBox control and save data to RTF format. However lately I started using RTF editor control that allows you to insert images into rtf. And although this works, the file sizes grow immensely.I was wondering if nowadays there are any better alternatives (preferably available for free) that people can use in windows applications for viewing and editing documents.

View 10 RepliesWhen I try to code in VB2010, I usually unmark the reference to Microsoft.VisualBasic. Because I do not want to use the legacy functions of VB6. I want to complete walk in .Net path. And I have found some alternatives for the old VB6 functions. But the rest not. Where can I find the list of those methods or classes (alternatives for the VB6 functions) ?(For eg: when I tried to find the difference of 2 dates, I couldn't find any other alternatives. So, I came back and used the Microsoft.VisualBasic reference for using DateDiff())?
View 24 RepliesI'm working on a small utility program and found that I have a need to copy the contents of listboxes, textboxes and other control from one to another.
I just started playing around with Drag and Drop but it seems lacking a bit...for instance, if I wanted to drag the contents of a listview to a text box, it doesn't look like I can do that easily if at all.
Can you use a drag and drop to copy the contents of different control types easily?I thought about using the drag and drop method for notification of the intent to copy the contents and then I would code the copying.
The idea (although I know it will be slow but that is okay for this utility) to copy the source to a textbox and then from the textbox to the target. The content won't be that large and speed is not a concern at this point.
Here is my issue if I have to do it this way.
1 - How can I use the control names to do this?
2 - How do I get the target control name?
I figured I would create a function that I would pass the source control name and the target control name and based on type, perform the appropriate method of copying the data.
I haven't figured out a way to get the target control name. I can use activecontrol.name for the source.
I have the need to constantly use the TabControl but somehow its current look is boring, is there any tricks out there to make it more interesting? Or what are the alternative controls that I could use to replace it?
View 3 RepliesI'm developing in VB.NET with Visual Studio 2005.I have a ComboBox (myCombo) on a form that gets populated within the Load method.I also have handled myCombo.SelectedIndexChanged to change a label on the form.
Edit: The way I added the event handler was by double-clicking on the combo box on the designer. Skeleton code then came up in the code view.It looks like what's happening is when the form loads, SelectedIndexChanged gets fired each time an item is added to myCombo.This isn't what I want, but I'm thinking there's another event handler that only gets called when the user changes the selection.
Here's some code for what I have:
Private Sub myDlg_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' this is all I do with myCombo in this sub
list = GetListOfItemsToAdd()
[code].....
Update: The solution I used was to remove the Handles clause after the event generator, and add this before the "End Sub" above:
AddHandler myCombo.SelectedIndexChanged, AddressOf myCombo_SelectedIndexChanged
I am currently working on a program that takes Visual Basic data in the form of a text file, and then stores this data in C++. Some of the data from Visual Basic is of the type Decimal. C++ has no built in type equivalent to decimal. I don't want to use double because there is a possible loss of significant figures if the numbers are large enough.One option is write my own decimal class.

View 2 RepliesAm making a game for a college project, its just a mario like game except its a frog.
I want the frog to be able to jump on top of a moving platform in order to get to the other side. However the timer doesn't stop and the frog keeps on moving down. The moving platform has a separate timer called timer2 and the gravity timer is called timer1.
Here is a picture just to show you the game and the frog falling through the platform.
For some reason the moving platform leaves a trail of itself, be cool if you could also fix that for me hehe.
Here is the code for the 'collision '
If Player.Right >= platform.Left And Player.Bottom = platform.Top And Player.Left <= platform.Right Then
Timer1.Stop()
End If

View 1 RepliesI want to create a RTSP/h264 video stream from static images, and incorporate it into my .NET application. So far I have found two possible ways to do this:
Use ffmpeg/ffserver, but I would need to compile ffserver on windows and then rely on it... and I don't necessarily want to rely on an external application
Use the LIVE555 [URL] library, but they do not have any .NET libraries, so I would need to spend some effort to make it work with the rest of my .NET application.
Can you comment on either #1, #2, or which is better. Is there a faster way to bring up a RTSP server in .NET? I do not mind putting in development time if there is a solid solution that takes time, but it would be good to have something we can work with fast, for prototyping and demos.
Until recently I have been using net 2005 with distributing an app which uses an access database with getting data using recordsets
I decided it was time to upgrade so I got net 2010 & started using ADO.net with a dataadapter.
To my dismay I have found that my app will not run on all platforms, ie XP, Vista 32 & 64 bit, Windows 7 32 & 64 bit From another question I have been told
"If compiled to target AnyCPU, your program will fail to run in an x64 environment if it utilizes any ODBC database driver. In this case, you must compile it to x86. Therefore, x86 is safer than AnyCPU."
Which I have found to be correct I am not familiar with all the options to open a database & the respective code required to extract/change the database data. I also don't understand the implications of using x86 cpu instead of any CPU
MY net 2005 apps have been working fine for the last 6 years (until W7 64 bit), so I want to develop an app that has the same lifespan without having to make variations to the build for specific platforms
I would like the answers to the following:
1. is x86 the new standard for specifying cpu & works on all platforms?
2. why does W7 64 bit have a windows & windows x86 system folder
3. why does my installer when "any CPU" is specified install it in the x86 system folder (W7 64 bit, even though the app fails when trying to open the database as outlined above)
4. which method of opening an access database is preferred which works on all platforms with a common cpu specified?
How can I ensure my app fully compatible with x64 Win7 platform? I have a choice of 32 or 64 bit development machines to use.
