VS 2008 : Conversion Of Hh:mm:ss To Seconds?
Nov 10, 2009
Currently, I have 4 textboxes displaying hh , mm, ss and ms.I am required to convert only the Seconds, Minutes, and Hours and display it into another textbox (see attached doc for diagram).I've got a brief idea that for the hours, i'm required to multiply by 3600, and as for the minutes, multiply by 60. Am i correct? Please correct me if i'm wrong. But as for the actual coding of conversion and how to display it into another textbox, i'm not sure how to do so.

I am writing a program and have run into an issue. The program requires a conversion of time (e.g. hours,minutes,seconds) to a hexadecimal value of no more than 4 bytes (e.g. FFFF). I have no idea how this is done. Can anyone point me to a tutorial or give a quick explanation. Sample code would be great as well.

Quick question - if I have a timer set to 5000 (5 seconds) and the code in the timer takes longer than 5 seconds to run because of sql stuff, will the timer wait until the code is done till it fires again?

I want to convert seconds such as 254565443 seconds to hours, minutes, and seconds and thought if I could remove the decimal and the numbers behind it and not change the number in front of the decimal then it would work.
dim seconds = 254565443
dim Hour
dim minute

I have a value in a report that's in seconds that I want to display as hours:mins:seconds .. in Excel I can divide the field/86400 and format as hh:mm:ss but if I do the same in the report viewer it just shows "hh:mm:ss" presumably because the field is an integer and not a date.What's the easiest way to show a seconds value as hh:mins:ss ?

when i run code after 60 sec it display following error what is this error and how to eliminate ?ContextSwitchDeadlock was detected Message: The CLR has been unable to transition from COM context 0x2040a8 to COM context 0x204218 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.

I'm uploading an image to url... etc. The trouble is my application stops responding for 5-10 seconds while the image is uploading. I want to use multi-threading to stop it doing that but I'm confused with the whole way to use controls with backgroundworker. [code] I guess its the textbox which is causing the problem.

I need to do a MessageBox.Show when ProgressBar1.Value = 1000 or after 10 seconds Button1 was clicked. For the second method, I thought of making a loop but I didn't know how to. I also need to search a string in a file (The string to search will be the text which was entered in a TextBox) and do different things depending on if the string was found or not.

I'm creating a program in VB.net that does the following:At a high level I receive a file in email, put the attachment in a monitored folder, import the text file to excel, format the excel, and then email the excel file to a list of recipients.
Here is my plan:
Completed: Outlook VBA to monitor all incoming email for specific message. Once message is received drop attached .txt file in a specific network folder.
Completed: (VB.net) Monitor folder, when text file is added begin processing
Not Complete: (VB.net) Import text file to Excel
Not Complete: (VB.net) Format Excel Text file.(add in a row of data,format column headers with color/size, add some blank columns, add data validation to some of the blank columns that allow drop down selections)
Completed: (VB.net) Save file.
Completed: (VB.net) Send file to list of recipients.
Obviously the items above that are not complete are the bulk of the work, but I wanted to get some advice on what some of you think would be the best way to approach something like this. The import and formatting of the file are causing me some problems because I just can't decide what would be the most efficient way to do this.
The way stated above. Import to excel -> format Having a template excel that contains all of the formatting already done for me and attempting to transition the data to this document (no clue if/how I can do this). Is it even feasible? Have the template already created and then import the text file to a new excel file, then transition that data to the excel template?
Something I thought about, in terms of formatting the document, was to record a macro of me doing all of the formatting that I'm going to need and then attempt to convert that macro into my vb.net code, but I'm not sure if that will work. I will need to verify that the text file comes in the EXACT format every time correct?

I need help converting this into PHP:
Public Function Encrypt(ByVal text As String) As String
Dim charSet1 As String, charSet2 As String, i As Long
Dim pos As Long, encryptedChar, encryptedText
charSet1 = " ?!@#$%^&*
[Code]...
I'm making a text to hash thing like presented above but in PHP for my website.. The code above is home-made so its nothing like MD5 or SHA1. But if you guys do know a way to encrypt and decrypt MD5 in Visual basic 2008 please show me! (this must also work for PHP).

i need to convert this code to vb.net
event EventHandler<PageEventArgs> IPageableItemContainer.TotalRowCountAvailable
{
add { base.Events.AddHandler(GridView.EventTotalRowCountAvailable, value); }
remove { base.Events.RemoveHandler(GridView.EventTotalRowCountAvailable, value); }
}
one of the online converters gave me this:
Private Custom Event TotalRowCountAvailable As EventHandler(Of PageEventArgs) Implements IPageableItemContainer.TotalRowCountAvailable
AddHandler(ByVal value As EventHandler(Of PageEventArgs))
[code].....
But intellisense complains that 'RaiseEvent' definition missing for event TotalRowCountAvailable

I created a program using VB 2008 to aid me on design work-related calculations that uses Access mdb file for displaying info. and calculations. But I experienced an alarming problem when I converted it to VB 2010 The program execution works in VB 2010 but it can't display the data from an mdb database file.
To simplify and simulate the problem, I created a simple identical program in VB 2008 and VB 2010 showing a window that displays a data extracted from an mdb database file. Both programs run as intended in each environment. When I open the VB 2008 created program under VB 2010, VB 2010 converts it and when I run the program, it doesn't display the data at all.

My issue is when I read from an existing executable and convert it to string and back to executable windows says it is not a recognized 32 bit or 64 bit application? The code below is real code I have rewritten many times but to no avail. If I leave out the part where I convert the bytes to string and just copy the binary and create a new exe with the binary the program works. But the whole concept of string converting back to valid binary has me stumped? This is Visual Basic 2008 code:
Imports System.IO
Imports System.Text
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim tempPath = System.IO.Path.GetTempPath

I need some guidance again =)Its regarding the conversion of voltage level to equivalent LUX.As mentioned in prev. few threads, if you have seen it, basically, my circuit board is connected to a solar panel and is connected to a power supply (those laboratory DC power supply used in schools).The whole thing is connected to the computer via a RS232 Serial cable port. Thru the serial cable port, a voltage level is sensed from the Solar Panel and is displayed on the "Voltage Level in Volts(V)" See attach image
Currently, i need guidance on how to convert the Voltage Level into equivalent LUX.I googled and found from this website >> [URL]../324003.page and it states that Lux = 1333 * Vo , so does it mean that i just type:TextBoxLux.text = TextBoxVoltage.Text * 1333 I'm not sure if this is the correct method to convert voltage level from the solar panel into equivalent LUX. If this method is wrong, please correct me.
[Defination of LUX: The lux (symbol: lx) is the SI unit of illuminance and luminous emittance. It is used in photometry as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface]

Okay so I have decided to upgrade my game from vb5 to vb2008 express edition. When I opened it I was told it needed to be converted so I said ok. However, there are some things in the language syntax that have changed.Obviously. Well here is one of them:
[Code]...
Setting controls to objects allowed me to cut down on typing but it seems you are not allowed to reference things without the "full path". I understand that you now have to set the full path of the object but doesn't setting something to an object already do that? Do I have to just delete the object references on the top and instead of using objCmbGraveU2 I now need to replace it with frmMain.cmbGraveU2?

I have a VBnet program that works fine and I'm hellbent on getting it to run under Linux eventually (looks like mono is the way to go sometime soon). But, for now, I'm looking at some of these code converters, online and otherwise and have some questions.
I tried a single procedure of code with the online converter and it threw quite a few errors relating to the procedure lines themselves (the opening Private sub etc, etc,)Something about C# and handles clauses -- can't remember.
So, I suppose the online converter just wants to see the code itself? As in, what lies between the Private sub blah -- CODE -- end sub?Now, what about something I saw this morning, "Sharpdevelop" that says it can convert entire PROJECTS to C#? (Also saw a 200.00 software package as well).
Is that the way to go? Will it do every bit of the project's code start to finish? You just load the project folder or the project file I guess?But then I see Sharpdevelop doesn't compile -- so you convert with it and then open the converted file with Visual studio C#.net?
I guess Microsoft will never have this conversion capability in visual studio?
