I'm looking to create a custom date picker with code examples from several sources.
Is the code to display/hide an ASP.NET control when a user clicks a button usually done with JavaScript or ASP.NET code? By display/hide, I mean within the page not a popup window.
how does one get to raise an event from clicking an item and goes to a new form show??
View 1 RepliesI've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?
Heres the tutorial with my new code encased in asterisks ...

How should I go about getting my mouse position over multiple controls, and such. I can't use the form_mouse move event, or any other control event nor can I use them all at the same time cause that would conflict with the actual position I need for an object.

ok so i have a PANEL control under a WINDOWS MEDIA PLAYER control. Both are same size.
The panel has a click event which shows a message saying "HI"
when the panel is behind the wmp control the message is not shown when i click on it.
so the question is is there a way round it, cos currently it only works if the panel is on top of the wmp control
I want to write an event that will simply display something when it is raised. I have never really worked with event driven programming before and am just trying to get a simple example working. It is not yielding any errors, but when I switch to debug mode I can see that the event it not raising correctly.

I'm trying to display the total extraction progress of a zip file as below. This gives me the total file size of all uncompressed files in the zip:
For Each backup In zip
TotalSize = backup.UncompressedSize + TotalSize
Next
I'm then using this to get the current bytes transfered:
TranferTotal = e.BytesTransferred + TranferTotal
The problem is this value resets after each file is extracted from the zip. I was expecting the above to "tally up" the total so I could use it for the progress bar but it seems to still reset after each item? Also, I'm using a global varible for the transfer total, if there a better method to transfer this information to the StepEntryProgress? The reason I'm doing this is because the DotNetZip Library does not support multiple extraction in this way, so I need to tally up in this way.
Code:
Imports Ionic.Zip
Imports System.Threading
Imports System.ComponentModel
Public Class Form1
Dim TotalSize = 0

i do have a treeview with it's property "DrawMode" set to "OwnerDrawText" because sometimes the display nodetext has to appear in bold format. Generally, thinks work fine, but after refreshing the treeview, the nodetext appears twice! Not only does it appear where the nodes are, but also on the upper left of the treeview control. Before reloading the nodes into the treeview, I use the treeview.clear-method to get rid of the old nodes in the treeview.
Here is the code of the drawNode-Event:
Private Sub TreeViewExt_DrawNode(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DrawTreeNodeEventArgs) Handles TreeViewExt.DrawNode

I have a datagridview bound to an Access datatable. It is nothing more than a one column list of chemicals. To allow the user to more easily navigate the list, if they press a letter it will jump to the first chemical alphabetically of that letter. If they keep tapping that same letter it will move down that list one by one. This all works fine. The problem is if you hold down the letter it will progress down the list but it doesn't show that progression. I want it to function much like if you hold down the down arrow key in a datable you'll see each successive cell be selected as it goes down the column.

View 2 RepliesI created Dataentry forms. In the form there are so many controls like DropDowns and textboxes. I am using Access database. Now I enterd the few records into the controls, and these records are saved into the Database. But now if i enter the any data which i recently saved in the database to the textbox or any other control then the remaining controls should be display the related data.
For example i have 4 controls in my form one is dropdown and 3 are textboxes. If i select the data in the dropdown then the remaining 3 textboxes shows the related data. How can i dispaly the corresponding data to the other controls?
I am trying to do something like:I have a cicle (For Each) which goes trough some items (existing N items)So, for each item read i have to create a control (a Label in this case) which must have the Click, MouseEnter and MouseLeave events . Each event will use/edit properties of the created control Creating those labels is easy but adding the event handler to the control i have no clue how to do it ... Believe me when I say I've spent a lot of time thinking about this .

I have a quick question regarding the serial port and timer tick event. Basically i have a micro processor connected to the PC via the serial port. With a baurd rate of 38400 set.When the PC sends the micro ":K + VBCRLF" the micro response with a string of information (ASCII encoded) and delimited with a "," and at the end of the transmission a cartridge return line feed is added.Example of sent string:
"12,1134,123,545,76,6868,34,232,1,2,3,6,7,8" These numbers are then split using the VB mystring.split(",") function into an array of strings, then the numbers are converted using ctype. After which my UI is then updated.I have Witten the code in a tick timer event using a timer count of 300ms. Although the program runs and the UI is updated i end it with lots of exception errors. I think allot of this is down to the serial port either timing out or not reading complete string.Or possibly the timer has not executed all the code before another tick event happens Even after adding a few try catch statements i am still having problems. Can anybody suggest a better way of doing it?I was thinking of using a do while loop and at the end a sleep function instead of the timer tick event.I need the speed as i am trying to read and display live data.

I have a menu item in a program that I'm working on called "mnuFileSave" The Click event goes through several "housekeeping" functions and calls the correct "Save" function.
Another menu item performs a function and depending on the results may want to call the "mnuFileSave".
I have tried RaiseEvents mnuFileSave.Click and get the error "mnuFileSave' is not an event of 'The_Entertainment_Collection.frmCollectionBook'
I have tried Call mnuFileSave.Click an get the error "Public Event Click(sender As Object, e As System.EventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event."
