Dim hashfromMd5 As MD5 = MD5.Create()data = hashfromMd5.ComputeHash(input)How can I get the percent of progress, progress related to "reading" the (input) -- using "data"? -- to be displayed live
View 1 RepliesI need help getting a progress bar to show percent in it. I want to have the percent in the middle of the progress bar, like is sometimes seen in a few programs. I have googled this, and can't find anything. I found something on The CodeProject, but it was just a label and drawing a rectangle behind it. I would like the actual progress bar that is available through the toolbox.
View 5 RepliesI have a DGV with a column bound to a Double. When I enter "1%" I get:
System.FormatException: Input string was not in a correct format.
I then try: MsgBox(System.Double.Parse("1%")) and get essentially the same error. (same for "$")
Is there a setting that will allow "$" & "%" as not only valid Double input but also do the correct adjustment for "%"?
I am having a hell of a time trying to md5 hash this with PHP... The VB code I am trying to port to PHP uses ComputeHash which takes in a byte[] and performs a hash on the whole array.

Dim oHasher As Cryptography.MD5 = Cryptography.MD5.Create()

I have a database application that generates a MD5 hash and compares the hash value to a value in our DB (SQL 2K). The original application was written in Visual Studio 2003 and a deployed version has been working for years.
Recently, some new machines on the .NET framework 3.5 have been having unrelated issues with our runtime.This has forced us to port our code path from Visual Studio 2003 to Visual Studio 2008. Since that time the hash produced by the code is different than the values in the database.The original call to the function posted in code is:

i have created some shareware applications. I implemented the following mechanism for piracy protection. Before Windows Vista and Windows 7 i did write a dll file to the System32 folder with an encrypted license key. Also in the Registry under HKEY_LOCAL_MACHINE i inserted a registry key.
The problem is that with Windows Vista and Windows 7 due to the User Account Control (UAC) this is denied.
I want to ask : what other mechanism can be implemented ? Where should i store the encrypted key file and the registry key.
I want that the application can be installed for all users of a computer only once.
If i stored the key in the user's application data directory then another user could easily just install it under another user account. Also i do not want to put the key file in the application directory because that would be too obvious.
note that i create the registry key with my application and not with the installer.

i dont know how to assign variables and im juist totally lost right now and this is due today and i was sick 2 weeks and am 2 chapters back.
I am trying to filter fields in a table that contain percent (%) and apostrophe (') characters. I kow that to filter an apostrophe you need to add another apostrophe (''). However, when a text contains the percent (%) character in combination with an apostrophe (') character, an exception is thrown. Also, when using the % character in a filter string, it will be function as an "*" (fields starting or ending with). I need the % to be considered as a character whenever the % makes part of a string in the field.

Is possible get the percent of a word in the content of a richtexbox? if yes, can you give me some example?
For example if I have 100 words in a richtextbox and I want to know what is the percent of a word in this content (for example if a word called "music" is repeated 10 times = 10%. If this is not possible in a richtextbox, is possible in other box like textbox?
i was wondering if it's possible to do such:
'form location Me.Location = New Point(10%, 50%)
i know this code doesn't work as it looks, just loads the location by pixels. this is just a question, hopefully with a working code for a marked answer..so much work to do and so many choices to choose from.
I have a filesystemwatcher which place files in a queue when they are created. From the queue the files are further processed (xml into SQL database).
The mechanism works fine, but I want to add a progress bar to follow the progress of the files in the queue: processing 1 of 10......2 of 10......3 of 10 etc.For testing, I created a batch file to simulate the creation of files, so the filesystemwatcher can to his work and place the files in the queue. When I tell the batchfile to simulate the creation of 20 files, I see that the amount of files in the queue change. For example;

In the app I'm currently making, I have two progress bars. One for current task being committed and the other is for overall progress.During runtime, I calculate how many tasks are being run and set that as the maximum. As each task completes, the progress bar is incremented by one.
I want the current task progress bar to show the progress of the current task. Some tasks can take a few minutes to complete so that progress bar works great. But, if the task is super quick, like editing registry keys, I see no progress at all.When I edit the registry, it basically goes like this:
'Edit Key
'x
'x
'x
ProgressBar1.PerformStep()[code].....
It completes so quickly that I never see the bar even move.I also have each task report its name into a label and it skips ahead so quickly that I only see the first task name and the last.Is there any way to make this do a better job at reporting the progress?
I came across a problem in my program it takes too long to calculate the values needed (about 10 sec) .But thats not the problem you don't know when the program is working or not, as it just locks up until its finshed and I view that as a problem.
I need to be able to show the progress of this .I looked at using background Workers but I get exception "Object reference not set to an instance" I believe this is because the background worker cannot write values or something ,As it works will a normal handler.

the code below shows an if statement that is determining a customer type and a discount percent for that customer.But when I run the code it only ever reads the first discount percent even though the allocated price range is above the first discount percents range and should therefore give the second discount percent and i cant figure out why it is not using the second discount percent in any of the bronze, silver or gold statements.
