I am looking to get some information on updating my own applications. Because what I have to do at the moment is replace the files every time it changes so I would like to know what are the options available starting with the easier ones or does it involve any third party applications. For example I have noticed some applications checks the files before it starts up and then asks a user if he wants to update it
View 4 RepliesI am trying to create a bunch of records, there will be a limited number of "Codes", about 50. Each "Code" is associated with a name from a textbox, I was trying to have it save each one when you click a button, to a .txt file.So, from the start the record will be blank, the person will go through the form, choose a number from a numerical up and down box, pick a name associated with it (both of these are mandatory and not implied). When they click the button, it will save the contents I talked about into a .txt file, say the number is #2, and the name is "Bob", the next time they try to change that value for #2, it will overwrite "Bob".
View 6 RepliesBefore I start, I'm not 100% sure this is the right place to ask. Okey, so I'm making my own Notepad, which will contain newer features. (Private use only though) One of them being tab control.
Now I want the program to be in the "Open With..." menus for all files, so I can choose myself.
And if the program is already running when user opens a new file, I want the text to appear in a new tab, instead of a new window of the program.
I tryed to be straight forward, and keep it short. So if you need more info, fell free to ask.
I have a general question on app.config, or the best way to NOT hard code a SmtpServer.Host = XXXXXXXX setting. I wrote this very simple SMTP texting application and wanted to have the settings not hard code but a form that read or writes to app.config or .ini or registry. my question is the pros and cons? and if anyone hae suggested or a link to sample project that is doing what I'm after. I have a single .exe and am new to vb.net and either want the exe to check for app.config, ini or registry if does not exist to create and then save added config, if the exe runs again it uses the newly created settings.
View 5 RepliesMy new office project is based on an MVP design and is in VB.NET (.NET 3.5), using multiple libraries (like EntLib, internal corporate framework, etc.). The number of DLLs used as references is so huge (almost 50) that when I try to build/debug the application in VS2008, it takes almost 3-4 minutes to get the website running successfully.
Wanted to know if there are any settings/areas which upon some modifications can help me reduce the build time? and what exactly can be the major reasons behind this long loading duration?
Whenever we need to handle events, we do it by creating a method which handles the event. Without creating methods; is there some other ways of handling events?
View 6 RepliesI have the following problem: I have a combobox in my application. Sometimes the data inside are too wide to be displayed (see here). Is it possible to use tooltiptext to display the whole data line if the user stands on this line? Or perhaps sending the whole data to a right-click context menu? If so - how?

View 3 RepliesI have recently released a free application for some game and now I have added a few features 'the public' requested.
I used Inno Setup to create the installer, which works just fine.
Now however, instead of having the ask the user to uninstall the current version, and then reinstall my new version, I want to be able to give the user an Update install exe which they can simply run and it will update the existing application.
One thing I would like is that the users Settings are not changed. So hence the following questions: 1. Where are the Settings stored? I thought it was in the user's Local Settings <Application Name> directory, but I cannot find my application there... I cannot find it in the All Users or Administrator 'accounts' directories either...
2. Are the Settings stored depending on the Version of your application? (Assembly Version / File Version)?
If 2. is true, then obviously changing the Application Version (which is logical in an Updated executable, no?) would also change the Settings back to default..? Can I avoid that?
Finally, is it enough to simply overwrite the executable? What registry 'work' do I need to do, or can Inno Setup do that for me? I am only using one other file which is the SharpZipLib DLL file.
As you can see from the picture there are two .ico files in Icons folder inside of the application. My question is simple - how to access those?
View 4 Replieshow i would make an application that can create exe files.Like i make an app that has the options:

way to update my application executable, and a few other application files for a simple application updater that I am using in my application. The code updates the files (including the executable, manifest, and a few other files), but on Windows Vista and Windows 7 machines you must run the application as Administrator in order for it to update the files in the application folder.

View 1 RepliesI need to know the proper way, or maybe I should say, the different ways to call another form from a parent or preceding form. I am currently using ex: formname.showdialog() to call my next form, but I am uncertain if I should be using that in every situation. [code] Whats the difference between these different methods? (ex: .showdialog() , .show() )I tried both of these to open a temporary form to retrieve a persons name from a database, so as the users progresses through my training program they can keep track of their scores.But, I also call other forms as I branch through my program, from the main page, to a secondary page, to a testing page, to a results page and then back to the secondary page
View 5 RepliesMy students did a tutorial in HTML Help Workshop to add Help files to a VB 2008 Windows application. They zipped the files and uploaded them to our class web site.
I downloaded them at home, unzipped, and tried to check, but every one shows Table of Contents or Index and cannot find the .htm documents for the topic. The same thing happened in my office. However, these projects work correctly in our classroom
lab and do display the .htm files.
Have a small application (forms) that I want the clients to be able to update.I am using one location on the server to store updates, and one for the original installer zip. Could this be a problem, in that both need to be in the same place?The app is in its infant stage at the moment, but I'd like to get it to update from day one.Which files do I need to put on the server in order for the app to update. At the moment I've tried the '*.application' file, and the 'Application folder' & its contents.
View 5 RepliesA routinely used application suddenly became impossible to access, with and error code indicating that the "VB Backup\Backup" file cannot be found. When I click File Open, the projects display as always. I select the application, double click the .sln file--and nothing happens. When I try to access the .vb file in Solution Explorer, it says "Cannot find VB Backup\Backup Files."
What are the Backup Files, when are they created, and why would they suddenly be "gone?" Is there any way to rebuild the Backup Files? I used the application last night and it worked fine. Today it can't be opened because the Backup Files cannot be found.
I have backups of the application folders, but get the same error message. Cannot be opened because the Backup FIles cannot be found.
Every time I compile my application, during install I get the error:Cannot download application, the application is missing required files

What's the best way of running an arbitrary number of Load() methods asynchronously and then ensuring DoSomethingWithValues() runs when all asynchronous threads have completed (of course without incrementing a variable every time a callback happens and waiting for == 3)
I'm trying con build a simple chat client/software (whole in on executable) wich start listen from the start on the port 5900 and when a client connect to that port the chat is established.

I'm new to VB and have over the last week or two been looking at the different ways to play audio (mp3's). Windows Media Player, Microsoft Multimedia Control, Bass.dll, SndPlaySound, MCI SendString and DirectX (including audiovideoplayback, direct3d and directsound.) I originally decided to use windows mediaplayer, mainly because it seemed the logical choice but quickly found out I couldn't get it to work properly.
So I installed the Directx SDK but now I'm completely overwhelmed about what to use and why. I need to be able run the compiled code on a win 2k box, play an mp3 from start to finish then load and play another mp3 from start to finish and so on. Whats the difference between the varied choices and which would be the best for me to use?
I want to know by how many different ways I can create an object. The most common usage I am aware about is:
