I am currently developing an application that will be the "base" for several components (business reporting systems, order management, etc). The idea is that our customers will install this "mother application", and we will offer components that will slot into it, expanding the functionality.
Now, here's my idea for how to make this work. I have some of this basic functionality down, but I want to get other people's opinions, ideas and experiences with this sort of thing before I move too far in a direction that might not be the best way to go:
I have alot of forms here who need 10 or more seconds to load when the method InitializeComponent() starts to run. It have a lot of pics for that is too slow to load. I need to do a loading screen to show while the initializeComponent() components is running.
I have developed win application on win XP with office 2003 using visual studio .net 2005.I am using Microsoft activex spreadsheet component.I installed my application on win 7 with office 2007, i get runtime error when i load the screen on ehich i have used that component. it says "Attempted to read or write protected memory. This is often an indication that other memory is corrupt"My AxInteropx.Owc11.dll and Interop.Owc11.dll are in same directory where .exe is stored.
I've seen some other responses about this and they talk about interfaces but I'm pretty sure you can do this with classes and base classes but I can't this to work.[code]....When it tries to convert whatever Activator.CreateInstance(t) returns to the base class of type Behavior I'm getting invalid cast exception. That type should be of CharacterController which is defined as a child of Behavior so why wouldn't it let me cast that?
I am using the Microsoft Encoder 4.0 dll's for capturing any activity. I have used registered dll as been imported in my project. but if the expression is not installed then there comes error in my application code.(actually the dll is missing to be used if expression encoder is not installed)."how to check for available dll and use it in my code?"
I now have a need to dynamically load a dll into my application and I've found the reflection/assembly information and it's fairly easy to implement so I thought I was on my way. However, I quickly found out that I'm only able to use 'shared' methods. What I was originally thinking was I could have one shared method 'library.beginprocess' and then that would make all the necessary calls to the other methods, but this doesn't work unless all the other methods and class level objects are also shared.
I feel like I'm missing something or somethings just going right over my head. I've looked at many, many sites and examples, but I've only run across examples that expose 1 method,[URL]..which explain how to implement a plugin architechture, which I have not tried yet, but maybe would allow me to keep my class structure the same without having to make everything shared?
Since I've been writing my prgram, I felt the need to provide documentation in much the same way VS2010 does.I've searched everywhere I could, but all the references I could find where for older versions of the IDE.It appears there is no builtin facility to produce documentation and this sounds silly to me.I found external programs, but at 300$ a licence it's way over the top of my budget.Even the hints and tips stickied on this forum are out of date, as they refer to VS2005.So how should I produce inline documentation for my classes
I currently have a XML file for an application I am developing. I have built a a XMLFile.GetContent function to read my XML File and load the content into a set of specific objects. These objects are then added to a collection and passed back to the main code to be loaded into the memory of the application.I am looking for a dynamic way of loading the information from the XML file into a specific Object Property. I have added comments to the function to show what I want to make dynamic.Content of XML File
I have started my TV Guide app. My appoligies to those outside the USA. I don't think it will work for you.I have a form with a WebBrowser component in it. I've named the WebBrowser "Display".
[code]....
This should make it open that website, but I get the error, "Value of type 'String' cannot be converted to 'System.Uri'."Opening that same link in a regular web browser takes you to the the desired site.I would like to do this without all the extra crap such as the igoogle stuff. I don't know a thing about htm/html programming, but I have uploaded the source including the websites and the source code for the sites.
I have a DLL that utilizes the Redemption Outlook Library. This is included in the DLL's Reference on the Project Properties Tab. This is a DLL that I wrote and one of its newest features is its ability to send an email.This DLL is called by a Click-Once program that has a GUI. When the program called the DLL and at the point of sending the email....I receive the "Cannot create ActiveX Component" error. So, in the Click-Once application, I also referenced the Redemption Outlook Library thinking that would fix the problem but it didn't. The Click-Once app resides on a server with other Click-Once apps. In it's irectory structure the DLL is also present and now....so is the Redemption Outlook Library DLL. I'm all out of ideas. Here is the code that sends the emails below.
Private Sub SendEmailToUser() Try Dim Application = CreateObject("Outlook.Application")
I have developed visual basic 2005 windows application on windows XP with Office 2003.I am using Microsoft Office Spreadsheet Component. I am using Axinterop.Owc11.dll.If i deploy my application on windows 7 with office 2007, My application gives error at loading point of that component.
so when i run my application it gives me error "unhandled exception has occured in your application. if you click..Attempetd to read or write protected memory. this is often an indication that other memory is corrupt."so i copied my sourcecode on that machine and debug. When i run my application in debug mode it won't give me error but if i run my application without debugging it gives me above error.
I found that it give me error in InitializeComponent() Me.xls1 = New AxMicrosoft.Office.Interop.Owc11.AxSpreadsheet CType(Me.xls1, System.ComponentModel.ISupportInitialize).BeginInit() Me.xls1.DataSource = Nothing Me.xls1.Enabled = True
[Code]...
Any idea how to resolve this error. axinterop.owc11.dll and interop.owc11.dll are in application folder.
I would like help with a script component in Visual Studio 2005 to take a text file as a source and convert it to Excel file (output). The text file uses a ~ (tilde) as the column delimiter.Also, can this be done without installing Excel on the server? Any and all suggestions are welcome. Below is sample I am having a problem with in the script component:

I am converting an old Vb6 solution to .net 2.0 in vs2010. I've been working in C# for about 3 years now and .net for 5. I don't recall having this problem in C#, but if I want initialize a readonly collection of DerivedControlFoo Is there a clean way to do it besides creating a sub to do it all off somewhere else? I'd love to be able to do it at the class level at the declaration for readability and simplicity.

I am using a DLL in my application that will probably be experiencing frequent updates. I want the DLL to detect the new version (I know how to do this), load the new version of the DLL into memory, and continue running. Is this even possible? So I need to know how to: Unload the current DLL. Load the new DLL. If possible, do this from the DLL in question. Is this even possible? If not, how close can I get to this?

I am trying to access VB.Net exe on a client system through LAN.Its working fine for server with static IP address.In case I try to access it with server having dynamic IP address, It doesn't provide access(config file containing server name).
In Order to access that exe with dynamic IP I need to specify current IP address of server in config file.
How it's possible to access that with server name as it's not feasible to change IP address in config file on daily basis
I've got a database that's 13,000 lines long and I'm trying to load this into a string array when the program loads but it takes approx 5-6 minutes for it to load it.I've got a MS Access database or an Excel file that I can load this information from, each has two rows: SVONo, Description This is my current MS Access
[code]...
Does anyone have any idea of how to make it faster? Or does anyone have a better way?I did have the idea of loading it by letting the user select the first letter and then only loading the ones that begin with that letter but I've got 4000-5000 'S' ones and it still takes about 2-3 minutes to load it All I want is to load the data from the database or the excel file and then put the products into 'cboProducts' and the 'cboProducts AutoCompleSourceList' and the descriptions into the 'txtDescriptions' AutoCompleteSourceList and a string array.Then when the user selects a product using 'cboProducts' the description will automatically be put into 'txtDescription'.
I am doing a project for part of my coursework which involves the creation of a series circuit designer.
I am having some trouble with the saving and loading functions; I had intended to save them to a text file with commas separating the component name and the value (if any) attributed with it.
Grid(xcoord, ycoord, 0) contains the component name. Grid(xcoord, ycoord, 1) contains the attached value (resistance or voltage- components such as wires have a value here of 0)
Once the save button is pressed, the text file contains 50 rows of "0".
P.S. Let me know if any other parts of my program are required.
Dim comp(maxsize) as ccircuits[globally declared] Const maxsize = 50 Structure ccircuits

I have a desktop application that shows a list of pdfs, and when the user selects one it shows it to him/her. I use the AcroPDF control for this, and it seems to work, but if the user goes back and forth between viewing the file and viewing the list, then the control randomly decides not to show the file (showing a blank page instead).
