my problem is the speed of the compiled vb.net program on VPN..after working 4-8 hours (without closing the software) the compiled program taking too slow. in reading the records or even modifying it..I installed it in VPN and the backend database is MS Access..
View 3 RepliesI have been playing around with different types of native code operations in Visual Basic and then inspecting the code with Reflector to see what kind of MSIL is produced. For example, I wondered, in a one line If-Then-Else different than an If-Then-Else split onto multiple lines, ie.

I've a requirement to have PreCompiled webpages and Non-PreCompiled webpages under same application. For example below is my structure:
/Bin
/Test1 (PreCompiled)
/Test2 (NonPreCompiled)
/Test3 (PreCompiled)
I would like these to have their separate "Bin" folders too if possible at all (I tried using "Probing" but I guess that's not allowed for web apps and defaults to "Bin" folder). If not that then definitely some ability for these to work together under one app/virtual directory because I'm not allowed to create another at any cost :(

I am not a programmer or anything like that but I have managed to create a little program.The program is for work. It is VERY simple - it adds a few figures the user inputs and then generates a text output so the user can copy and paste it to a customers diary notes on the customers account.Here's the problem: It works on the managers computer but not on the consultants computers who will be using it! The reason it doesn't work is because the normal consultants computers don't have .NET installed :( The solution is simple - install .NET! lol however the company I work for is quite massive (corporate size) and our department is quite small and insignificant so if we want to install something like .NET on all the consultants computers it will take around 6-8 weeks! Now we desperately need to start using this mini program ASAP! Is there any humanly possible way to run a Visual Basic program without installing .NET? Is there some kind of file I can download and put in the folder of the mini program that will allow it to work?
View 2 RepliesI'm buying a new computer this week and the one I want has Windows 7 Home Edition 64 bit. I program in VB.NET using VS2008. If I write a program and compile on this 64 bit windows, will it run in 32 bit? I did some reading and from what I understand is if it is not using any specific 64 bit drivers I should be good. I'm not doing anything fancy that I know of as far as drivers. I just wanted to see what everyone's past experience has been.

View 5 RepliesI've got a 3rd party C application that's compiled to a non-.NET non-COM DLL. It has one simple function declared like so: Declare Function CapiTaxRoutine Lib "taxcommono.dll" (ByVal sInData As String, ByVal OutputData As String, ByVal intINPutLength As Long) As Integer
If I place the taxcommono.dll in my path (C:WindowsSystem32 is what I'm using because it's what the vendor recommends),I can wire up a call to the function and it works just fine.It returns a 1 or 0 for success/failure, but it also sets the value of the OutputData string parameter (using some C pointer magic I'm not familiar with) to a huge fixed width format return record that has the data I need.When I call it from a .NET .exe application, it works just fine.When I try to call it from an ASP.NET application via a referenced compiled .NET wrapper DLL, it runs but can't set that string.In order to get it to run, I can't have taxcommono.dll in my path, but rather have to place it in my Bin directory of the web project.Does anyone know of a reason it can set the pointer when called from an .exe application but not when called from a web app?The .NET wrapper DLL I'm using works when called from our ERP software, which is not web based. But when I add a reference to that same DLL in the web app, it won't give me that output value.am used to just getting a return value instead of a function setting the value of one of my input parameters.
For the last two days or so, I've been trying to get a program to compile another program that will extract a series of files and run them in a given order, like a self extracting zip archive.The program compiles fine and compiles sub programs, but I am unable to go about correctly embedding the resources.The output program shows the large amount of data ( ~12mb from the file I've been embedding to test ), and there are no compile errors.However, I cannot get it to access the resources correctly. It will either result in a compile error about the resource image not being valid / containing any resources, or a friendly "System.Resources.MissingManifestResourceException" being thrown.
View 1 RepliesI have a VB .dll from a previous developer that I need to modify. So I de-compiled it with no errors and then exported the code. I tried to compile the project and get two syntax errors:

New SqlDataAdapter(DirectCast(command, SqlCommand)).Fill(dataTable)
The error message just says syntax error, nothing else.
I am making an application which will have a member list for my clan (with listbox), and times of warnings (with label), and conflicts people have had with this member (listbox).I want my application able to add members (with saving in file), and remove members (with saving in file), and remove warnings (wth saving in file).As I dont know how to split and remove and store stuff in a single file, it'd be impossible for me to code. That's why I come here and ask if someone can code this for me.Some of my friends said it could be possible by splitting each line, in the following format in a .ini (doesn't have to be .ini it can be also a non-format file) file:
[M]Member1|IntWarnings|Conflict1-Conflict2-Conflict3[M]
[M]Member2|IntWarnings|Conflict1-Conflict2[M]
This friend can't help me now, because he suddenly had to go offline, he might not come online today aswell.I have already made the interface, but as I said before, I have no idea how to code this and would like some help with this application.All the members I would like to store in: lstMembers (Listbox All the conflicts per SELECTED member I would like to store in: lstConflicts (Listbox)The warnings per SELECTED member, I would like to store in: lblWarningI want to know if this is all possible and HOW, since I have no idea what Split can do.
Our application is one EXE and multiple DLL's. Right now, we are compiling all of them for x86 so we are forcing 32bit because the running size of the application is a lot smaller (memory usage).If we compile the EXE as x86 and the DLL's as anyCPU, on a 64bit machine will the DLL's be 32bit or 64bit?
the reason for my question is if i can compile the DLL's for anyCPU and then have two EXE's, one for 32bit and one for 64bit, then i have only one duplicate program for the 32 or 64 bit change, and if a user wants to run full 64bit they only need to run the 64bit EXE and everything is fine. But if a user is on a 64bit machine but wants to run in 32bit mode, they would run the 32bit EXE.Let me know if this is true. i can't test this as i develop on a 32bit XP machine.
I imported a VS 2008 project, and eventhough my project is compiled for x86, the intellitrace will not run and says that the project is not targeting x86.
