I have a GridView, named GridView1 used to getting data from SQL Server Database, because the data from database always changing, I would like to get the new data to display on the GridView1 when a user press the "Fresh Button"
I tried:
GridView1.Refresh() - did not work
Me.Refresh() - did not work
Me.Hide() then Me.Show() did not work
[Code]....
I want, when I show Form2, the form1 should be displayed in background. And when I close Form2, the form1 should be updated or starting complete new Form1. I do this but there are two tabs of Form1 in TaskBar. One is background display Form1 and another is updated. I want only one Form to be displayed.
View 9 RepliesI've been working on this game the past few days, a simple game where two people control different tanks, and shoot each other, very basic so far.The problem I have is when one player is dead. I have the form recognizing each players death by using this code (It's within a timer subroutine)
'Player One Dead
If intPlayerOneHealth <= 0 Then
btnReplay.Visible = True
End If
[code]....
and that code is replicated for every key pressed (Arrow keys, WASD, e, and end). Those booleans are handled in a timer subroutine, where if the boolean is true, they will move/shoot. (Turning the booleans to false is done in the 'Private Sub KeysUp' subroutine)
TL;DR How do I get the game to restart itself when a player dies and hits the replay button?
P.S. I've tried 'Me.Refresh()' as well, and that didn't do anything
I am trying to place a repeater within a repeater using xml data. I have it working exactly as I want, but the method I have used reloads the data for each repeater. I think I need to cast as an XmlNode but I'll be honest - I have no idea where to start. Here is my code - I'd like to keep everything in the code behind if possible.

I have a gridview control on my asp.net page(vb.net). I also have a "cancel" button, that when pressed, is supposed to clear the gridview of it's current contents.
However whenever the cancel button is pressed, it just reloads the page and the gridview is still there with the same data that I wanted clear.[code]...
I have a listbox, a textbox, and a button. The button populates the textbox with the selected item & value of the listbox. As below:
Protected Sub GetVariables_Click(ByVal sender As Object, ByVal e As EventArgs) Handles GetVariables.Click
Me.txtLetter.Text = lstNames.SelectedItem.ToString & lstNames.SelectedValue.ToString
End Sub
The problem I have, is that when doing this it reloads the page each time. Any way around this?

I am new to using databases in applications and i have a code to select data from the database. However, the first time the application starts, new data is inserted into the database which is needed after. But, the data does not appear until the whole application is restarted. How I can refresh the database content.
The current code for selecting the data is:

Dim cmd As SqlCeCommand

I save all the form controls(texboxes,Labels) with name and location in a XML file.
I want to retrive the XML file into a form(Reloading) with the same controls.
I have created a file say "abcd.xml".I have created this in a device which can be connected to my system and synchronized(which means data from the device can be synched to the database and vice versa).Now when I reset the device all the details in the device is lost but it exist in the file. When we do a reset and do a sync I need to check a condition and if its true I need to load the details from the file to database.This is what I'm supposed to do

View 1 RepliesThis happened to be once awhile ago and I thought I had the solution, but apparently I don't. Very rare, but what happens is, I'll start a new project, build my controls on the form, go into the code window and write some code. I'll save this all out, but when I reload the project, the code window comes up OK, but the design window is just gone. The code for the form and all the controls is still there in the form.designer window, but the form itself just will not appear, and there is no icon for it over in the Solution Explorer to click on

Ok so I have designed a program to figure out commissions for phone sales at my company. Since the devices we sell and their associated prices change over time, I had to make that data within my program dynamic. I have a form within my program (frmprice) that has 160 textboxes - 80 for the devices and 80 for the associated prices. Now I hard coded the .text members with default values for our current stock of phones and prices.
I also added code so whenever that form with the phones and prices (frmprice) closes it saves any changes that have been made to either the phones or prices and when the form loads it overwrites the default data with any data that the user had entered at last run.
HERE is my logic problem. At the very first run the program is overwriting the default hard coded values with "" because no user data has ever been entered before. So when the form with the prices loads, it passes the user entered data from last run which is null because it has never run before. If I test to see if default value <> the user entered data before it executes the code to pass the user entered values it will always test to be true because the user entered data is null at first run. If I test to see if the default value is = to the user data it will always at first run test to be false because there is no user data yet.
HOWEVER once the user entered data is initialized (anytime after the first run) I need the program to pass the user data from the previous runs back in. Just NOT at the first run. Here is the code i am using: (in the code below the variables ending in "val" are the ones that are of the type string and are saved in the application settings) The frmprice_Load Event:

I have declared a webbrowser control on my form and assigned a URI to it upon load. This works fine and the webbrowser.documenttext is set to the html of the document. What I need to do is on the second run through of the program it needs to refresh the page to check if the code is still the same. I have the following code set but it appears as though after a refresh it is not working because if the code is changed it still sees the old code in webbrowser.documenttext.
browserRedgis.Refresh()
browserRedsnap.Refresh()
browserParks.Refresh()

I have a datagridview control. I want to save the rows and then restore them the next time I run the program.
How do I write the rows out to an XML file?
I know how to fill the rows from an XML file. But when I've done so I can't add any more rows. It gives the following exception when I try: Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound. What can I do about this?
Or is there an easier way to save and restore the rows?
I have looked around and cannot find a way to download an image from a webbrowser without reloading the image or webbrowser AKA using the cached image.

Currently, I am try to get the email addresses that have been saved or stored by the user of the computer. This isn't the emails that the user has sent or received, or the contacts he/she has in his address book. Just simply the email accounts that have been accessed from the computer.I know that there are some locations stored in the registry that have the email account. The email addresses that are used on the current computer. I just can't seem to find them on my computer.I am not sure if the registry is the only place to find it or if it stored on the web browser such as internet explorer or google chrome.
View 1 RepliesI am writing an application that connects to a specific com port. This com port can change depending on how many physical ports are on the PC, and if other USB devices have installed com ports before this one.
I have the communication to the com port all working great, but I need to get the com port description not just the "COM#" which is all I currently get.
I found in the registry where the description is stored but am having trouble doing what I need.
In this key:
Code:
HKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass{4D36E978-E325-11CE-BFC1-08002BE10318}
there is a varied number of sub keys. The are numbered 0000-NNNN depending on how many ports you have. Inside each of these keys, there are multiple values, although I am only interested in one or 2 of them.
My problem is, that I do not know how to get a list of the subkeys (the 0000-NNNN keys/folders) from the original key I posted. I have looked through a few registry tutorials, and I can view the default value in the listed key, but I could not find how to list the subkeys of the listed key.
Does anyone have any sample code they could share that shows how I can get a listing of subkeys, and then run through those subkeys checking for a specific value in one of the strings contained in the subkey?
