.net - Delay In Slider's Two-way Value Binding Causes Choppy Behavior?
May 7, 2012
I'm binding the value of a Slider to an integer property that represents the volume on a networked device. This network request takes a little time (usually <100 ms), and somehow causes the Slider to feel choppy.Here's my oversimplified code to clarify:
Private _playbackVolume As Integer
Private _deviceForDemonstrationPurposes As New Device
Public Property PlaybackVolume As Integer
[code]....
Binding to the PlaybackVolume property will cause the setter to fire while still dragging the thumb. Because of the network latency issue, the slider is locked for however many miliseconds it takes for the request to complete.

At work we have this really old excel spreadsheet with movable points in it.This feature no longer works in '07 so I have decided to try and make a VB form to replicate it's functionality.I have the concept down of what I'm gonna do, I'm using sliders for the movable points and I'm using a data grid view for all of the numbers they are just going to type in, and then I have a button that saves all of the data to the database that it links with.I've figured out how to get everything working except the button that saves the data. So there are 4 separate databases attached to sliders and another one that is part of the data grid view. What am I going to have to put into that button under the click event in order to make it save the values in all of these databases?

I know that time delays have been covered before around almost everywhere. however a method that forgoes forcing the GUI to become temporarily non-responsive, is all but a myth, or at least to my findings. i have the need for a GUI program to delay before the next command, however using the current method, detailed following, it causes the desired effect however it dose make it much less polished as when you click anything else on the GUI it goes un-responsive for the directed time. [Code] make a sub called say Tdelay( milseconds as integer) and have it run a loop as many times as the milseconds variable indicates and each time making the thread delay for 1 milsecond and then update the GUI/form in some way, then re-loop.

I have 22 30x30 shapes(players) moving around a simulated football field. This is the culmination of 2 years of basement hobby work and it looks pretty good except for some choppy movement. With 11 shapes moving around it really looks good, but doubling the load causes the flicker to be noticeable.I have double-buffered the control that does the drawin

I tried to skin my application and failed. I can get it to work if I don�t have semi transparent pixels on the outside of my form. But I want to use a skin I found on Deviant art that was made for Miranda. It is really nice but and it has a shadow around it. To get it to work in vb.net (I�m using 2005 btw) I have to fill around the main picture and take out the initializing (I think that is what it is called). But then the form�s edges are choppy. How does Miranda allow the shadows but I can�t in vb.net?
I first tried to do it the easy way. I set up some transparent panels with transparent pictureboxes in them and put my corners and middle fills as the backgrounds. I made the form with no border and set the transparent key to transparent. That didn�t work, so I made the form magenta and the transparent key magenta. The outside of the for where the shadow is was drawn on the magenta and the magenta bled through. So I edited the png�s to be magenta all around the form (eliminating the shadows) and it worked, but the corners were choppy.
Then tried some code I found on the net that tried to make a new control as a transparent panel. It was overriding the paint events and drawing to an off screen bitmap. I really didn't understand it and it just showed up as a blank screen. There has to be a way to do this.

I've been searching for days. I can't find anything that I think is going to work. I've probably read the answer and skipped it because I don't get it. I'm new. I've researched multithreading, sub routines and webbrowser. The webbrowser thing doesn't seem professional to me.
All I want is the animation to be smooth when it's displayed and to have it integrated into the app so it's not called from the local drive.The animated gif is in PictureBox3. Please point me in the right direction. I really don't want to use a static image.

I am adding data points to a MSChart spline type graph, and the graph that is displayed after I am finished adding the data points is very choppy and not like a proper spline curved graph. It's more step-like than flowing. if I manually add data points to each series I can create a very smooth and flowing spline type graph. Here is the code that I am using to add the points:
For c As Integer = 0 To count - 1
Chart1.Series(0).Points.AddXY(c, Array1(c))
[code]....
Is there a step that I am missing or a parameter that needs to be set for the spline type graphs for this issue not to occur?

I am upgrading from VB6 and started working with VB.Net (VS2005). One problem I have was controls avilable in VB.Net. I can use a slider bar in VB6, but couldn't find any quivalent in VB.net(.Net Framework Components)!! I don't know why I can choose one in COM components, but these requires project generated DLL's to run. I want to distribute just the executable.My questions are:
-Is there any slider bar in VB.Net Framework Components?
-If there is none, Can I use COM component and bundle everything into one Executable? Also is it possible a list of controls in .Net as I find in vb6: url....

in my company intranet, there is a webpage with a js slider. While moving the slider, some textboxes are updated dinamically.
I am trying to change the slider value and submit the form programmatically, but the value sent to the sevrer is always the original "step 1".
If I change the value using the usual
document.getElementById("slider").setAttribute("value","2")
the value changes correctly but the textboxes don't change their values and the info sent to the server isn't the value just changed because is made in js to get the current displayed value.
a way to update the value needed to the server, and make all textboxes update dinamycally?

I am trying to make a form expand from one size to another using a slider animation.
The problem is when I run it the form resizes but without the animation. I'm not sure how to use the animation when resizing the form. It works if the form is a set size and then I run the animation.
The form is borderless and starts out with a width of 11 and I want the final width to be 285.
The resize and animation are triggered by clicking on the form.
Here is the code.
Private Sub Form3_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Click
Me.Width = mintformmaxwidth

I have a set of x, eg 288, data values. The user wants to fit a regression to a subset of this data, eg (2 - 200), then she wants to analyse within a subset of this fitted range, eg at 20 and 100. So, on my form are four Hor. Slider Bars, to set the lower and upper bounds to the fitting and the analysis. The two that set the lower bounds work fine. The two that set the upper bounds are getting corrupted somehow outside of my code and I do not know how to solve this problem. What happens is that when I click on the right hand arrow on the slider bar, the program runs through my function with the correct values whilst the arrow is down, goes out of my code and then immediately comes back into my code, but with the wrong value set into the Hor. Slider Bar fields that I am working with, eg the .Value field. The new value is always 9 below the maximum that it can be, but I can see no connection to this number.

I'm trying to make a slider, or a custom scroll bar, whatever you want to call it, in VB 2010. But I want it to act as an usual scroll bar. I simply can't make it stay inside my form, it just moves around. I have a photo of my code and my designer down the thread. What should I add? I tried to make it stay inside Panel1.

In VS2010 I have VB.NET codebehind aspx pages and I'm using Ajax multihandleslider extensions to filter search results on numerical values.
Fistly, the multihandle sliders don't display in the designer... I have to remove the slider targets tag:
In order to make it display in the designer... this isn't so much a big issue but an annoyance.
I am displaying items in a given category. So I get the max and min prices for all items in that category and assign the sliderextension max/min values appropriately.
This works fine until... I change the item category and go get a new max/min value for the slider control. I set the max/min values, then I set the target textbox values each to the corresponding max/min values.
The slider handles don't repaint (or init?) properly Like say for example my initial min/max is 1/100 if I do a full postback and change the max value to 1000 then the slider bar (correctly) stays the same size but the handle appears WAYYYY to the right off the page and I have to scroll to it. When I click it, it shoots back onto the slider bar.

I'm realy green when it comes to programming but I like to think I am learning quickly. However, I cant figure out how to generate a number of random numbers baised on the vailu of a numeric slider. So for example I am generating a number between 1-12 where each point of value for the slider would generate an indiigual number that can all be added to a final total. I would also like to be able to back the slider down to a previous number and have the same total I had last time I was at position x. This is what i have so far:

I use objectbinding to display client data in a datagridview. The datagridview also contains a counry-column allowing the user to choose the country of the client.Unfortunately, databinding of comboboxcolumn does not seem to work if an own business class is used. Using a simple collection instead works well.Copy the sample code into a new windows project and the programm runs fine. Then comment and uncomment the two lines with "XXX" and the code will fail. Why and does anybody know how to make the sample code work by using the business object class(variable named "newClientListVariable" in the sample)? [code]

I started programming in VBA, then graduated to VB6, and I am now using VB.NET 2008 Express.I have read, in the various posts, that I should keep Option Explicit and Option Strict both on, in order that I use correct VB.NET code and not VB6.I am trying to do that but am totally confused with the results of one of my programmes that was running perfectly with Option Strict off, but now advises:Option Strict On disallows late binding. To me it appears that I am using early binding, but to be honest I am not clear on the binding situation. I have checked through a number of google items, and a number of this Forum's items without seeing the light.[code]
