I need to trigger the onmousedown property of a table contained on a web page presented in the WebBrowser control of my form.The site is a nested frames mess, but in this particular frame the tables are basically used to create large, context buttons. In other words, you click the table and are navigated to a subform.[code]At first I thought this might be handled by using InvokeMember("click"), but that has no effect. If I try InvokeMember ("onmousedown") I receive a javascript error on the page. Can anyone tell me if/how one invokes the onmousedown property of an object inside of the WebBrowser control?
View 4 Repliesa datacontext defined in a module(domain services ado.net ria)a page having add/delete methods whenever any method is executed, it is found that all the previous actions (NEW RECORD ADDITION and DELETION OF RECORDS) are carried out before the new action is carried out normally
this behaviour is not prominent but "when using break points and inspecting the values of the variables and table object to be added to context, it is clear that all the previous actions take place again. even when the datacotext. savechanges is called, even after that still all actions carried out on the datacontext repeat themseleves, when any new action is to be carried out
How would I use a hotkey to simulate a button click?
View 2 RepliesI am trying to simulate human temperature taking. Basic i just need a button, a text box , a progress bar and a timer.What I want to do is that when the button is clicked, the progress bar will slowly increment and after it reaches maximum, a random number in the range 35-40 will be generated in the text box.Now so far, this is what I`ve done:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Start()
Dim r As New Random
[code]....
So the progress bar is working fine. The random number generator too. But here are my problems:
1-Once the button is click, the number is generated. I would like that to happen after the progress bar reaches maximum.
2-So this is suppose to be a temperature gadget for kids and therefore when a certain amount of temperature is reached...an alarm is sent to the parents. How do I generate a dialog box (to acknowledge an alarm was sent) in case the temperature exceeds say 38? The dialog box should close after some 5 seconds. If possible, in case of such excess, the button color should turn to red or otherwise(no excess) blue.
In .net how do I fetch object's name in the declaring type. For example...
public static void Main()
{
Information dataInformation = new Information();
}
public class Inforamtion
{
//Constructor
public Inforamtion()
{
//Can I fetch name of object i.e. "dataInformation" declared in Main function
//I want to set the object's Name property = dataInformation here, because it is the name used in declaring that object.
}
public string Name = {get; set;}
}
I need code for getting the Submit button to click on this website.url...i checked the page source and have been able to get the username/password to enter on my Webbrowser. However, I cannot figure out how to grab the Submit button and simulate a click.I managed a work around in which I set the focus on the "password" element and used SendKeys to send ENTER, however I don't want to use this method.

View 1 RepliesI've designed an Order Entry System and now I'd like to send an email when an Order has been saved to the Database. I could probably do it from the client machine pretty well, but really what I was looking for was to inform another program running on the server that an Order has been saved into the database with OrderID:xyz. And have that program take care of sending the email. I have no problem designing this second program, in terms of the basics of responding to an event and sending an email. But my question is: how do I raise an event across the network that this other program will respond to?

I've created a program that creates a registry value when it is run, and when this program is uninstalled I need it to remove this registry value if it exists. So I wrote a little command line VB.NET program that simply checks for the reg value and removes it if it exists and I added this to the Uninstall section of the Custom Actions tab in the Visual Studio deployment project that I created for this app.
I know that the command line app works because if I run it myself manually it deletes the registry value, but when I uninstall my application it does not remove the registry value so obviously this command line app is not being executed.
is it possible to perform an action when the tab key is pressed in a textbox or the mouse cursor is moved to another box?

I was observing my programs process in the task manager and noticed each action made to the program made the memory continue to rise. So I added a Garbage Collector and since it's my first time using it im not sure if I implemented it right. I haven't gotten any errors but I ran some tests I would like to go over with everyone. After adding the GC I was able to notice a change in the memory my program used- it was reduced.I added the GC to the main forms formClosed event of my application which is used in different scenarios. I also added it to the panels paint events before I tested the program. And noticed a quicker reduction in memory. The Form i mainly use called frmLine1t5. This form calls to the database based on which line to test. Then the form sets the controls that were added in design view to be enabled or disabled based upon the product for that line. This process was easy to implement.I Load each new frmLine1t5 to a collection of the form so people can run multiple tests using the same form. This helped so i didn't have multiple forms for the same type of process. I had to access the forms through a collection so I knew which controls to populate to the correct instance.
I noticed during my testing that I can not add more than 50 items to this collection. The problem is that I remove the key from the collection upon form closing, so I dont know why it has gotten to 50.The test I made Runs two timers. Timer 1 is set to tick every 4.5 seconds This timer loads a new form and tests a new line of product.Timer 2 ticks every 5 seconds and closes the previously opened form.I have it get the GC Total Memory upon loading the form of frmLine1t5 and upon closing the form of frmLine1t5.the results are shown in the picturesThe errors i have gotten occured when ChildForms Open: had reached 50Here are the errors:
[code]...
Possible Causes:I think that upon Form Closing it is taking longer to finish closing before a new form is loaded... But isn't vb.net suppose to finish any unfinished threads? Even if the program is single threaded?And because the form closing isn't "happening" then the key is not removed from the collection.
i have a button and if a specific option is set (via a checkbox) then once every 5 times the button is clicked an extra event happens.I thought a counter/Integer would be the way to do it but i cant seem to get it quite right, heres my code i have in the buttonclick event:

This program posts inside many forums (you can choose). It's main objective is to allow a user to distribute their posts to many forums easily without opening each individual page on the in a web browser therefore you get more points to your filehoster's account.

I'm not really sure what I'm supposed to be doing with this. It's a new setting I just added and it's empty, so I'm not sure if that has anything to do with it or not. Anyone know what's going on and what needs to be done to get it to accept a value and not want to be "initialized"?
I have recently gotten my hands on a free, open-source IMAP connection API.So far, I have been successful in creating a connection to one of my accounts.Where I'm getting stuck is retrieving folders and/or emails from those folders.Does there happen to be anyone here that is familiar with this API, or even Gmail (particularly the folder structure for IMAP)?
If not, here is a link to the DLL that is listed on sourceforge and the company's website that created it (if you feel like testing):

When I run that code, I get an error that states:System.NullReferenceException: Object reference not sent to an instance of an object. (The bold line in the above code).
Now, I'm not sure exactly what that means. Does that mean it tried to access the server and "INBOX" doesn't exist so it gets returned a NULL value? Or is it possibly the coding itself?Maybe the Gmail folder system is weird due to the fact they use labels (even though from what I have read online, the labels act as the folders in the IMAP system).
What is the problem in below code.
