View 6 RepliesI have a program that reads from a database...the database pulls its info from a site.it measures in 0 to 100 (%).I know it takes 3 days (i dont know if its EXACTLY 72hrs)..to get to 100%.Currently, i have a progressbar to read from the database field..which is the value.I'd like to 'estimate' the time left before it reaches 100...Is there a math formula for that?
View 3 RepliesI made a sort of downloader program in Visual Basic 2010, and it downloads okey. It reports the full size of the file, and how much that has been downloaded right now and the percentage.
But, a function that i am missing is to show the user how much time is left on the current downloading. I have searched for it, but i couldn't find any solution that would work.I should also mention that i use a webclient for the actual downloading part.
I created a software which download files from the web. I also added a progress bar which shows the download progress. Every thing works fine.
Now:
- How can I add a label that will calculate the time left for the file to be downloaded and another label that will tell the speed of the download?
- Would it also be possible to add a label which calculates the size of the file that is begin downloaded?
Here is what I declared:
Imports System.Net
Public Class Form1
Dim WithEvents Download As New WebClient
Dim WithEvents Download1 As New WebClient
Friend WithEvents Label1 As System.Windows.Forms.Label
Here is what I have under the download button:
Download.DownloadFileAsync(New Uri("URL" & ComboBox1.Text & ".rar"), Textbox1.Text & "" & ComboBox1.Text & ".rar")
And here is what I have under Download_DownloadProgressChanged:
ProgressBar1.Value = e.ProgressPercentage
Label1.Text = e.ProgressPercentage & "%"
If ProgressBar1.Value = 100 Then
MsgBox("Download Completed!", vbInformation, "Info")
Label1.Text = "0%"
I have an app that encrypts a file, and I would like to have an estimate of the time remaining, but I don't know how.

i have a datagridview i have an edit button associated with each row. on CellContentClick event i am dynamically deleting and creating number of textbox and label controls in my tablelayoutpanel this dynamic deletion and creation of control is taking some time also flickering (well thats not a big issuse)but the problem is if someone continuously keep clicking on edit buttons of various rows after some time the whole tablelayoutpanel is a complete mess.
accordng to me this is happening coz my CellContentClick event is not geting time to complete and before the event get complete one click the edit button of some other row . and i am unable to handle this situation

I am tring to make a price check calculator and in order for me to do that i need my users to choose their price level.
Right now i have a small web form created and its quite simple but i need my button for onclick to do link to corresponding forms that it goes to...Right now i have it as:

The program I am trying to make needs to be structured like this.
Table 1: Estimates (Details View)
Customer ID
Employee ID
Form Factor
Problem
Proposed Solution
Estimate Acceptance (Boolean)
Table 2: PartsList (Grid View)
Part Number
Part Name
Part Cost
Now, the trick is, I need to have it where each Estimate can have its own individual parts list. It needs to be this was as each estimate could have just one part, or many parts. How can I do this effectively? I already have the tables and the layout of the app, I just need to get it all connected up.
I am currently using following code to estimate the size of the textbox:
Dim i As Integer, j As Integer, pGr As Graphics, sz As SizeF
For i = 1 To pNumRows
For j = 1 To pWidth
sb.Append("W")
Next
[Code]...
I was wondering if there is any way to remove the for-loops and do away entirely with the pGr (textbox.CreateGraphics) method and still correctly estimate the size of the textbox.If you're wondering why I am (actually the person who wrote the code) is looping through all the 'W', it's because (I think) 'W' has the biggest width and height in the entire character set, so the person (who wrote the code) is trying to guess the maximum area needed.

View 3 RepliesIs there any way to download multiple files at the same time from a remote server? How I am doing it currently is I get a list of files from the target folder on the server then I loop through that list & download each file 1 at a time. For 100 small files it takes about 45 seconds. I'm guessing that the bulk of the time it takes is logging in to the server for each file to download, so 100 files means it has to login, download & logoff 100 times. Is it possible to login just once, download the 100 files then logout?

View 4 RepliesI am trying to figure out an easy way to add custom plugins for the app for additional features, without people having to download a whole new update each time.i guess the way i'd want it to work is,the program will auto detect the plugin file. Then, add's a specific value to either a button array, or add's a picture, etc.Once that button is clicked, it will open a new form designed the way i want it. from within the plugin itself.So its a module.What would be the easiest way to do this?

I got a panel that i am adding labels to. I have autoscroll enabled on it so when they fill the viewable space it scrolls. but i need to put the labels to the left unviewable space(when left scroll is already at 0) The label is placed but i dont get the scroll bars and i cant force it to scroll to a - value.
Is this even possible? Same thing with UP.
Or is the Scroll only limited to Bottom and Right?

The Name of the file that the user is downloading The Url Were the file is being saved The Size of the file The speed at which the file is being downloaded And the Status. But the Problem is that the downloader can only download one file at a time. How can i make a multiple file downloader Which if the user wants to download 2 or 23 files he can.
View 13 RepliesI wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.
