Make An Auto Updater - Program Crashes After Having Downloaded In A While?
Sep 24, 2010
I'm trying to make an auto updater. It kind of works, but I've got some problems.I need to make the download threaded or something so you can use the program while downloading. I've tried the background worker and now the Application.DoEvents(), but I didn't get it to work.
The second problem is that the program crashes after having downloaded in a while. It may be because it isn't threaded, but I don't know.Anyways, here's my

I have been working on a Minecraft Skin Downloader for some time and learning a few things here and there but making an auto updater on VB is one of the things i am having trouble with. I have made one on VB but problems arise here is the code for the updater. I have it where in a text document in dropbox(Public) and it will say the version like 1.0.0.0 for example and since that text document can be changed you will be prompted to update when I change it but I need to have the version of the updater.exe to 1.0.0.0 in order for it to work and say that your up to date. Because at this point it will just keep prompting you to update because you don't have the 1.0.0.0 version the of the updater.

I would like to make an Auto Updater like this one on this thread: [URL] but without having to click on any buttons to update the files... I just want my launcher to update users's files when they start it... As I am beginner in VB.net (I started like two days ago) I really don't know how to code all this!

I had a post on it but i ran into the same problem. My program downloads a text file from server and checks it.
It works but it makes the program crash for 4-9 seconds.I was thinking of downloading the file more slowly or using Threading()

I have encountered a small problem with my application due to the updater I built in.Basically the way the updater works is:1) Check for updates2) Download the new .exe file as "tmpMyApp.exe"3) Download "Rename.exe"4) Launch "Rename.exe" and exit application.5) "Rename.exe" then deletes the old application and renames the tmp one with the origional name "MyApp.exe"6) Launches "MyApp.exe"This all works completely fine for me, except when the program is installed in "C:Program FilesTinyGrab" this causes my app

I'm trying to make an Auto Login program, which requires me to do a few clicks. I've tried many of the methods found here on MSDN, but they don't seem to work. The code I'm using to simulate the left click is:
Private Sub leftclick()
Call mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0)
Call mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)
[Code].....
When I use this code, it always comes up with the following error:
"A call to PInvoke function 'DyKnow Login!DyKnow_Login.Form1::mouse_event' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature."

I wrote this VB program to be able to throw a device we developed into programming mode where we use an ATMEL Flip installer to upload new firmware. I can program one device after another running the application off of Visual Studio Express 2010 or Visual Studio 2010, but when I go to publish this file and run it on another machine, it becomes unstable and crashes after each upload. On those same computers if I run the raw unpackaged program under Visual Studio Express, the system does not crash, and I can program devices repeatedly.

I am using VB.NET Framework 3.5 . I have a very complicated program with over 40 forms and 100s of lines of coding. Earlier today, this program worked perfectly. I decided to change the Assembly Name from APA to Salamander. I do not get any errors and things seem to be going fine. Upon the next debug, the splash screen loads fine. (I am using a timer to proceed to the main form, not the inbuilt splash screen setting as I found it to be more reliable). However, when the main form loads, none of the pictures (resources) load and it exits itself immediately yet no errors appear at all. I think it might be to do with the .resources file but I really don't know. As I only started Visual Basic less than two months ago I'm not sure what all the files other than .vb files actually are.I really don't want to have to completely rebuild the program as my release date is in five days and as I am still at school I don't have time to complete it on top of homework. I have tried changing the assembly name back to APA again but it still does not work. I am completely stumped.

I have an application that I have built that used a winsock control to send commands and receive data from a wafer map program. I have been converting the winsock to use the built in sockets in .net and so far things have been going fine. I have been able to get it to connect and send out a command to the wafer map. Yet I have having a troubling error that I can't resolve.

my situation is this; I have a search button which searches records with Surnames, when two or more records have the same surname, the first record appears and 4 navigational buttons appear, they are 'Go back to first record' (btnFirst), 'go back one' (btnPrevious), 'go forward one' (btnNext) and 'go to the last one (btnLast)'. All of these work properly except for 'go back one' (btnPrevious). When I click this and the record is currently the first one, the program crashes. Its probably a very elementary mistake but I can't figure it out. Here is the code for btnPrevious
