I am making the belated transition from VB6 to VB.NET (2008). I would appreciate some guidance on writing arrays to a file. I need to save and load large arrays of 4-byte floats (24 x 90,000 values is not uncommon). I can load or save them using nested for-next loops, but that's quite slow. I'd like to find a single operation that can read or write the binary data.In VB6 I could accomplish this (writing case shown) with Put #1 , , MyArray()I can read and write single variables from binary files without problems in .net. For example, [code]I have looked and looked, and Googled endlessly, but cannot find out how to accomplish a single-line numeric, floating-point array read or write in VB.NET.
I've been researching all over Google for how to Read/Write Floats, Doubles, Longs and String to memory. I believe I have the reading Longs, and Floats working properly. I'll post my Module (which contains all my Read/Writting).[code]
I compiled some VB6 code on my Win7 x64 machine and the result .exe will not run correctly on any other machine. VB6 code is just a new template .exe file with one button, a reference to "Microsoft ActiveX Data Objects 2.6 Library" and the following code in the button press event: Dim db Set db = New ADODB.Connection It runs correctly on my machine, but no others (even other Win7 x64 machines) (Update: I found TWO other users where it runs and one of them is Jeff Atwood!, but most machines have the same problem)
I am tightening up my coding with the Option Strict set to ON. It has now produced alot of errors. An example of this is:
If AllocatedDGV.Rows(i).Cells("RoomNumber").Value = RoomsAvailableDGV.Rows(j).Cells("RoomName").Value Then
It gives me the following error: Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity.
I need to write an interface to get data to/from our data files.
We have a low level class that holds field values for each record read from the files.
This just holds two values, the value read from the file (DBValue) and the updated value that may need to be written back to the file (CurrentValue).
These values may be any of the standard value types (integer, date etc) or a string.
Either value (DBValue or CurrentValue) may be null if not defined.
I have written the class to manage this data which works fine while option strict is NOT on.
But we have an office policy of having option strict on all the time.
When I put option strict on, my object value comparisons fail with the error: "Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity."
Question, how should I change the following code to handle option strict on ...
2. Is there any way to tell when it will be available if it still is a service that Microsoft provides?
3. Is there any way of telling what I might be doing wrong, if anything?
The message I receive at all hours anytime I try this (about 10x so far) is:"We are sorry, we are unable to process your order at this time."without any explanation as to why or when I could be able to process the order.
Ok ive looked all over the web but all I can find is examples in other programming languages (cant convert). Can anyone shed some light on how to make a dll that works with rundll32 (just the basics) or tell me were i can find info.
I am attempting to make a browser. I have it set up to where it can support one proxy. My question, is, How would I make it to where the program would read from a text file, and use those proxies? 1 proxy per line?
I am developing an application in VS 2005 (VB.NET) that should run on both 32 and 64 bit OS.The Framework is distributed with the application. Microsoft has two different FW redistributables dotnetfx.exe for 32bit OS and NetFx64.exe for 64bit OS.Is there any installation file that can detect the OS type and install correct redistributable?
I would like to add some scripting support to my .NET-application (I usually code in VB.NET). Since VisualStudio 2008 won't let me use VSA to get scripting support, and the Windows ScriptControl crashes in 64-bit mode, I have been looking for an alternative solution to my problem.I would really like to be able to code the scripts in VBScript or VB.NET, because of the simple syntax.Would it be possible to implement some kind of sandbox inside my application to make it run a VB.NET application inside itself? Or is there any simpler way of getting scripting support?
I'm writing a media management tool and want to add support for MTP based devices.I've been reading through the SDK docs and with the help of some C# examples have managed to make a start on getting some VB code working.
I've come across a few anomolies that I hope someone can help me with!In the examples IPortableDeviceManager.GetDevice appears in C# to receive a string array. But in VB.NET it appears to only receive a string. I have a similar issue with IPortableDeviceManager.GetDeviceFriendlyName which according to the C# samples appears to receive a char array, whereas in VB.NET it is accepting a UShort.
One last hangup with an application and I've tried like heck to research this but no luck.When I do a button click on my open file, it brings up a sub with all the open file code same for my save file and everything works perfectly.If, the open file dialog is on the screen and you should click either cancel or close I get the following argument exception unhandled, (and I've pasted all the details).It throws the exception at the very first line where textbox1 gets it's backcolor(txc(0)) is the variable in my.settings
If I open ANY file I have saved by clicking OK, all goes perfectly, it loads the file and I don't get the exception.I only get it when I click off the open file dialog with cancel or X.
I have a number of functions that, for one reason or another, return data type object.If I try and use the + operand (or indeed any arithmetic operator) on types object the compiler throws a wobbly.
How do I tell if a given object supports the "+" operator and, if it does, invoke that "+" operator?
I'm developing a new SOA system right now, and would like to use WSDL2.0, but I heard some clients are still connect using VisualBasic and WSDL1.1 (mostly from excel sheets and stuff). So I was wondering if VisualBasic also supports WSDL2.0, or if it's all 1.1
I know WSDL2.0 will work with C#,Java,and most other typical application programming languages, and these languages will be used by most of our clients, but I don't want to alienate our VB users, so that's why I'm asking.
Well I am using Visual Basic 2010 Express Edition & I have already coded support for buttons & sticks for the most part basically(I can't detect the two different triggers as two different values so I can't know when one is partially down when ones pushing in the other stick or letting that one go) I can't detect the guide button....also I can't make the controller vibrate...
Is there a way to solve this? I don't want to download C# express edition or visual studio trial & xna just to try & get code for C# which may include code I don't know what I need to copy(+translate to vb) or classes/functions not available in the Visual Basic language.
Can anyone help me so I can make this from VB? I want them to be able to use the buttons to move around the user interface(not a game), the guide button to be used to bring up a menu to turn off the controller & such like that & vibration feedback so they are sure when they pushed a button & an action was carried out for example....
---My last post was moved off-topic telling me to post in the xna forum but I don't want to build this using xna game studio or C# language that you must have installed to use xna game studio....I need this code for VB.NET if it's even possible to do at all, reccomendations to use XNA/C++/C#,F#, etc...these will be ignored as I don't want to have to download & install XNA or the express editions for all the different coding languages just because one thing in my own isn't turning out easy for me to work with.
If i had the money for visual studio this would be no big deal but im a single developer basically(all the coding for the program) & don't have enough money for the tool that could allow me to easily make a project using any language I want without having to download & install all the express editions seperately & start them up seperately when I want to work with certain projects.
I've downloaded latest source from mono project, compiled it and everything works (c# projects, mod_mono, xsp) except vb.net. Vbnc, mono's vb.net compiler does not exist after compiling mono from source.This is on CentOS 5, on Ubuntu 10.04 I installed mono packages via apt-get and vb.net just works.
At work I have a 5 screen setup for programming applications etc. I need that many screens becouse I usually program HMI devices that consist of many screens.Ofcourse with the arival of VS2010 and some real multiscreen support I coudn't be happier. I mean actually programming with 5 screens! That would be some awesome multitasking.Unfortunatly that dream was quickly crushed to dust. After installing the VB 2010 Express edition to test it out I started it up and all 5 screens started to bug / flicker / change resolution... and never stops doing that, so I must reboot to recover from that bug. If I reduce the number of screens back to just two then everything works again. Add a third screen and the whole party starts over again.
Now this might be just a problem of the graphical devices that I use (Kensington USB graphics adapters) whom do not support any form of graphics accelleration... Then again, just one adapter does work fine so that actually shouldn't be the problem. I wonder if anyone else has managed to start up VS2010 with more then 2 screens? For now i'll stick to VS2008 as that doesn't bugs out with more then 2 screens, eventhough it doesn't have multiscreen support.
