View 2 RepliesI am making a mass emailing system that reads off of a xml document and sends an email based on the stored object made from the XML tags.This program will have to send hundreds if not thousands of emails out. I made a test XML document with 160 emails to be sent out to my address.The program gets a (not responding) after about 10-15 emails, (although it keeps sending). Also the email sent counter lable doesn't change at all during the sending, the progress bar works however.Also, when I tried running it it stopped at 140 emails.

I have a user app written in VB which up till now has relied on winsock to connect to another device we have. The user app logs onto the device and then send / receives status reports from it which are used to set the controls on the apps forms.
This has all worked well for a long time but I'm now looking to move away from Winsock as I know it's not 'the right way' to do things and I also need to be able to send non ascii characters between the app and the device it's connected to (implementing multi language support).
The issue is with Winsock it would simply throw the DataArrival event when a message was received and I could then process the message and act upon it. When using a TcpClient socket connection I'm running into problems as all responses are on the socket thread which means I can't simply change controls on the main form without using the Invoke check.
What I want to be able to do is have the thread running the TcpClient simply alert the main form thread when it receives data and make that data available to the main thread so it can start processing it and triggering all the other functions etc required (these also interact with the Form). Whilst this is happening the TcpClient monitors any further messages and sends response messages as requested from the main thread.
I'm uploading an image to url... etc. The trouble is my application stops responding for 5-10 seconds while the image is uploading. I want to use multi-threading to stop it doing that but I'm confused with the whole way to use controls with backgroundworker. [code] I guess its the textbox which is causing the problem.
View 1 RepliesI 'm having no trouble coding, I'm back to my initial printing problems. The program printed Avery labels in a variety of sizes. I created the label templates on 8.5 x 11 forms and then printed the forms. This cannot be done in VB 2008 for a variety of reasons:
1) The form size cannot be larger than the screen size I got around this by creating a new form class that matched my dimensions.
2) printform only does screen shots. This was a major barrier. First of all I can't get printform to print my custom form because it's not a member of system.window.forms.form, it's a class in system.window.forms.usercontrol. However, even if it was in the correct class, it wouldn't work correctly because printform in VB.net, does a screen capture of the form and then reduces the image on the printout.
So that is my dilema. I do not know how to use the reporting tool, but I can see that it must be binded to a database. Although my application does use a database, I want to be able to massage the data before printing it. And the application does more than just print labels. There are also custom reports that need to be printed.
I'm building an application that outputs a list of usernames to an HTML document. I'm using this to generate a string:
For y As Int16 = 0 To intBuddyList - 1
strBuddyListHTML = strBuddyListHTML & strBuddyList(y) & "<br />"
Next
The resulting string is then put into an HTML document. The problem is, when I load the document, the brackets are displayed literally. When I view the source, I see this:
buddy1<br />buddy2<br />buddy3<br />buddy4<br />tbuddy5<br />tbuddy6<br />
Is there a way to preserve the brackets in the HTML tags?

In order to multithread correctly, so that my UI gets updated and the background code functions correctly, I've been doing this:I have one sub that does the UI updating and checks for invocation: [code] However, I need to update the UI within the Class now. When I do that, my app is no longer responsive. I need to do all UI updating within the form class and all background code within my custom class.I just can't figure out how to determine at what part my class is at, to update the UI.The UI has a few labels and a picture box that needs updating. As it runs a new process, (about 8 in all) I need to update the picture box and labels with the appropriate information so that the user knows where the app is at.
View 7 RepliesI have been working on a quite complex multiform solution.All of a sudden the start up form (in fact any form I designate to start up) loads, displays and operates fine.
But when I try and show a form using showdialog the form displays behind the original form and I can�t set focus to the ide to close it down. I have to use task manager or alt f4 while the form has the focus.
Calling different forms from this one gives the same result but other forms work fine. I don�t want to redo this form as Ive done a lot of work onit.The only thing I can think of that whist I was changing the startup form in the project propertied page (file>project>properties) I unchecked the �Enable applications framework checkbox.
I have made a form that consists of textboxes nested in groupboxes nested in tabpages. I want to check if all textboxes are empty in every groupbox and even if the controls from a groupbox in a groupbox are empty.When they are empty i should not create an element string for my .xml document.Below is the code that I have at the moment. I call it with the form as the parameter.

For Each c As Control In ctl.Controls

It does uploads everything according to the way I want it to but the problem is.. It becomes not responding when uploading big sized file.
i have nearly finished my game matchmaker now and im stuck on one final thing... this is how the app works...form load -> read line by line from a text file -> query each line(witch is an ip) -> display the data in a line in a listbox... this loops round for each line(ip) in the text file and make a new line in listbox each time... all works just right im very happy... now for the problem im having...
while this loop is running if the query finds an ip that is not online (game server is not up) it just stops and dose nothing atall BUT if i make a seperate query for say 2-3 ips with the ip hard coded so it takes the loop out if an ip is not online it tells me server is offline so is there anyway i could make this do a timeout or something... like if the server dont respond withing 5 seconds it closes the connection to that query and moves on?? my code is below for all of the above..

ListBox1.Items.Add("Users" + "|" + "Race Lenength " + " | " + "Track" + " | " + "Realisum" + " | " + "Server IP" + " | " + "Server Name")

I've recently tried to "publish" my vs2010 VB.net app, and ever since then, that particular program isn't working. It's taking minutes to build where it used to be seconds and if it enters a breakpoint, vs2010 quits responding.I did "repair" vs2010 and that didn't help. I also ran a program I was working on previously and it builds and debugs just fine, so I know it's not VS2010, but has something to do with the solution that I "published". Prior to publishing, everything was running just fine.Is there anyway to undo whatever action or event I somehow triggered?
