I need to generate a class at runtime similar to System.Resources where you can add a resource eg 'picture.bmp' and it immediatelly is accessible as 'System.Resources.picture.bmp'. I presume I need to generate XLM or/and XLSD at design time and then deserialise at runtime but I cant find a reference on how to do this. Specially without knowing the generic class in advance (as 'System.Resources' doesnt know all the resources in advance).
Public Class Subscribing Private _subscribingObjects As IList(Of String) Public Sub Add(ByVal obj As SubscribeObject)[code].....
Is there a more elegant way to add do this? One class would suffice, but since the Add methods have different arguments, then one really wouldn't work.
In a windows forms application I am attempting to read a file from a share into a filestream.I then start impersonating and write the stream to another share that only my impersonation account has access to.This works fine for small files. But if I attempt this on a 90 meg file I recieve a "Insufficient system resources exist to complete the requested service" error on the following line:
I'm trying to make a V.O.S, (don't ask) and I have 2 questions:
1: how would I run programs in my resources files? (For example, if i included "Random.exe" could i do Process.start("Random.exe")? or what would i do?) Also, how would i add resources and settings files at runtime? is this possible?
My app bundles a set of VBScripts (UTF8 text files) into a VB.NET assembly. I used to embed the script code into the classes as String members, but this is proving to be a poor design. I want to include them as resources instead. What's the best way to add resources to the CompilerParams?
What I've got so far (excluding all the error checks):
Dim comParams As New CompilerParameters() comParams.OutputAssembly = DLL_Path comParams.ReferencedAssemblies.Add("System.dll")
[Code]....
The CompilerParameters contain fields for EmbeddedResources and LinkedResources, but from the examples I found so far these seem to pertain only to framework resources???
Is ist possible to Add or Edit Resources of .Net Applications at Runtime because I want that the User is able to pick a file and that is automatticly added to the Resources so the Application can use that file later on.
VB.net VS2008 My program dynamically populates a class as I click on specific calendar dates runtime. I am currently using various LINQ statements targeting this class for reporting purposes. However, all of my LINQ statements are hard-coded. Are there available solutions / modules which will provide me with a LINQ command and RESULTS window which can be set to an instance of a class so I can experiment with other commands runtime? Can LinqPad be used runtime against populated classes?
I have a vb .net application where the user can choose a directory into which an excel file is written. If the user selects a system directory (yes, my users do this, don't ask me why) then a System.Runtime.InteropServices.COMException is thrown at runtime. I am handling this exception telling the user to please select another directory.
Is it possible to access a class or module at runtime that isn't part of the initial application. Simplest way I can explain it is this.Application A reads from DatabaseA and gets a list of "classes/functions/modules (what ever you would like to call them)"Grid gets populated with a bunch of data, one col has the above mentioned info User double clicks on the cell and that function is "fired off" Bascially ApplicaionA would have all the classes that would be needed for the instructions to run.line 1 might look something last this
Columns would be (just an example)
last run | instructionFile | path of instructions | some variable use in the instructions
I'm getting a collection of processes, adding them to a ListView, and deleting them from it when needed. All of this is done in a timer. The problem, is that after a while, the app freezes. I think this is because I'm not disposing any variables.
Here's my VB.NET Private _processes As New List(Of String)() Dim killedProcs As New List(Of String)(_processes) Dim processes As Process() = System.Diagnostics.Process.GetProcesses() For Each proc As Process In processes [Code] .... I tried disposing of my process list, but the IDE wouldn't let me. That's the only thing I thought would need disposing since it is what hold all of the processes.
Since most of the projects I work on are exclusively SQL Server 2005/2008 database driver, I was wondering about the implications of using System.Data.SqlTypes classes as data types in my VB.Net Framework 4.0 code.For example currently I define integer variables as Dim X as Integer.Using System.Data.SqlType classes I would define my intege variables as.Dim X as System.Data.SqlTypes.SqlInt32 implications for performance, serialization and databinding. One difference would be that all variables would default to Null.
I remember seeing somewhere on the net that there are classes in .Net that will return information about your computer. I know that System.Environment returns some of this information like MachineName and some other stuff. Are there other classes that will return information such as hard drive size, free and used space, total memory, used memory?
We have migrated our Vb6 application to VB.NET using a third party tool. Now we are in a process of Refactoring and introducing object oriented concepts in the application.
In VB6, we were using structures in many places. As a part of introducing object oriented programming,
1. is it a good idea of changing all Structures to Classes? or Is there a concept of "Generic Structure" similar to Generic collections, Generic classes?
2. Can some one guide me any source containing guide lines or best practices for applications that are migrated to VB.NET from VB6 and implementing object oriented programmaing.
I was wondering if there was a way to find out how much memory a data structure too up. So say I declared a list of strings. Dim theRN As New Dictionary(Of String, Integer) Say it had 25 elements in it. How to find out how much memory those 25 elements are costing me?
I am fresher in vb.net but I want to develop a project in this case I want to use the system.Configuration namespace's specific calsses. But I am not clear which class i use and why it's function and it's use.
i am trying to add a mpg file to resources. at the time of compiling it throws following exception.the size of file is 200mb. [code]how is it possible to add a large size file to exe resources?
I have been developing some components for our products at work, and one of them is based off the flow layout panel.What i would like to do is provide a custom designer for it, but without loosing the features provided by it's default designer (System.Windows.Forms.Design.FlowLayoutPanelDesigner) which is marked as internal.Using Reflector i thought i would just implement it again myself, seeing as it inherits from 'FlowPanelDesigner and that from PanelDesigner` all of which are internal.
Why would these classes be specifically marked as internal? Is it due to them being specifically for Visual Studio use, and thus not 'framework' code?Also, is there an easier option that re-implementing all the functionality?
My software handles multiple operations on files, and I have now finished writing the related functions, using the System.IO classes. I now need to add support for network drives. Using a mapping works very well (although Directory.GetFiles is a bit low, and I don't know why), but I'd now like to be able to deal directly with paths such as \192.168.0.10Shared FolderMyDrive. Is there any way to handle this type of paths other than mounting the drive to an available drive letter, using the newly generated path, and then unmounting?
Exists a good tutorial or example that shows how to use these classes from namespace System.Drawing.Imaging.
My idea is, to produce Bitmaps and to compress them. I don't know if for my case IO Streaming is important because I don't want to save the bitmap on my hard disk.
I would like to utilize classes that inherit the System.Data name space.Specifically, I would like to have classes CarColumn, CarTable, and CarSet derived from DataColumn, DataTable, and Dataset respectively.I would like to be able to add additional properities to each class. As an example this is how I would like to reference items within the classes:
I Have just been watching a video on throwing Exceptions. Are you supposed to throw System.Exceptions from within your custom classes. to the calling code, Which other way can they communicate. I have read in several places it is bad practice to throw SystemExeptions.

Most of the time this works as it should, but sometimes it encodes a string and the gives an error on decoding it. The error message is: Invalid length for a Base-64 char array.
I seem to be having a problem with controls that I am creating as new classes (not UserControls) inheriting from an existing system control. Everything seems ok while I create the control code, through to the compile (which is successful and adds the control to the toolbox) and dragging the control from the toolbox to the GUI surface. However, when I then debug or compile the project, I get a message such
One element of My.Settings is a Specialized.StringCollection. This has been working fine for months. Starting two days ago I always get the following message -
