Build A Date Calculator Utility (DateCalc)?
May 10, 2011
I am trying to build a date calculator utility (DateCalc). It returns the number of days,weeks, months etc between two dates.I worked hard and long trying to find out how to convert a date into a format on which you can perform math operations (for the "what's the date in 'n' days time" part) and it works! I can also use the minus operator to find out previous dates, from say 10000 days ago... BUT...I want to develop it further, and this is where I need help (i am still very newbie remember)Can you help me to find a way to code this bit to ignore weekends and saturdays or sundays individually, and a range of dates in its calculation? I have two datetime pickers and a some checkboxes.DTPickFromDTPickToChkBoxExWeekendChkBoxEXSaturdaysChkBoxExSundays An image of my form and it's components is here :--> [URL] Also, as part of my 'Datecalc', I'd like to find the dates of every other saturday and sunday in the future.

I'm trying to build a scientific calculator with vb .net, except it is vista glass :-p
I basically want the user to be able to enter an equation like SQRT(5 * 6) / (2 ^ 4) and then I want vb to use system.math to solve it. If I write this in my code, vb is able to do it, so how could I do this at runtime.

Dim myRequest As System.Net.WebRequest = System.Net.WebRequest.Create(url)
Dim myResponse As System.Net.WebResponse = myRequest.GetResponse()
Dim rssStream As System.IO.Stream = myResponse.GetResponseStream()
Dim rssDoc As New System.Xml.XmlDocument()
Try
rssDoc.Load(rssStream)
[Code]...
Folks this is what I'm using to parse an RSS feed for the last updated time. Is there a quicker way? Speed seems to be a bit slow on it as it pulls down the entire feed before parsing.

Does VB9 provide a compile-time date/time stamp function? I know VB6 did not; I'm hoping VB9 does.

I would like to calculate a new date simply by using the build-in dateadd function, but take into account that only weekdays should be counted (or 'business days' so to speak).I have come up with this simple algorithm, which does not bother about holidays and such. I have tested this with some simple dates, but would like some input if this can be done in better ways.This sample assumes a week with 5 business days, monday-friday, where first day of the week is monday. Dateformatting used here is d-m-yyyy, the sample calculates with a startdate of october 1, 2009.
Here is the simple form:
Dim d_StartDate As DateTime = "1-10-2009"
Dim i_NumberOfDays As Integer = 12
Dim i_CalculateNumberOfDays As Integer

I am creating a splash screen for my vb.net 2005 app (.net 2.0 framework). I would like to include the build date and time on the screen without having to manually enter it myself everytime I do a release.

I have a "ClickOnce" application and on the Splash screen I display the Version. I am also displaying the "CreationTime" (see below) that I thought was when the Build or Publish was done. Today I realized it is displaying the date/time when the application is actually installed on the PC. How do I pull the date when the this version was compiled, Built, or Published? I really do not care which -I just want a constant date the sticks with that version. I'm using VB 2005.

I have two Integers
[Code]...
Now of course these change as my game moves forward however I have to add for example 15 months. Now I'm lost at how to calculate this. Ideas I've had. Add 15 to 6 which equals 21, devide by 12 you get 1.75. Add one year to the DateYear and with the .75 I would do 12 * .75 which equals 9. So DateMonth = 9 DateYear = 2011 Which is fine I guess, here is where I got stuck To add DateYear and DateMonth I had to convert to Single. How can I split the Single at the?

Anyone know what jailbreaking does to an iPhone? If so, is there a way to make a program to jailbreak 3.1.2 in VB or in RealBasic? I guess it'd have to send commands to the hardware and software of the iPhone, and communicate with it pretty well...

I am looking for information on using mstscax.dll in VB. The goal is to create a utility that logs into a remote service in the same manner as remote desktop. However, my utility is not required to show the desktop.I have a series of commands that I will start off with that will look for users, reset logins, shadow, and message. I have been using a batch file on my RDP to perform these functions, but we are already looking for more functionality and power than what the batch commands can offer. I am googling 'mstscax.dll' but the results have been less than satisfactory although I continue to search.

A particular VB.NET project is actually throwing 'Build Failed' But when I try rebuilding again it says 'Rebuild Succeeded'. It keeps alternating this behavior. Kind of random. Any vbc.exe issue of long locking the PDB or xml files?

I have a vb.net 2008 windows form application that I was just assigned to work on. how to maintain and test changes to both the pre build and the post build events? Can you tell me how to test these events? My postbuild event, I believe calls a project file in the solution file that wraps files together in a bundle in debug mode. Can you tell me how the posbuild event works and when it is called?

I am using 2008 Express Edition. I am trying to make a Release build instead of a Debug build.Under Tools->Options, Projects and Solutions->General - I checked Show advanced build configurations. The option to switch configurations does not show up in the IDE.
After this, I went to the Project Properties->Compile and switched the Configuration from Active(Debug) to Release.After building, I looked in my project directory, however only in the Debug sub-directory was the .exe and nothing in the Release sub-directory.I have used Visual C++ Express Edition, where I noticed that if you do not change to Release in the IDE than after changing to Release in properties, resets the project to the last configuration setting which is usually Debug.how to make the Debug/Release box available in the IDE, since Tools/Options does not make it show up?

This is kind of an off-the-wall question but does anyone know if VS 2010 has somekind of utility that will allow you to just drag & drop controls onto a form or something that will help in visual design. I'm just talking for visual purposes only. No code-behind files or anything...almost like a canvas where you can place controls and labels, etc.

I have a CodeSmith 6 project setup in Visual Studio. I added a class with a shared method (VB), but cannot refer to it in my template. I also tried adding an assembly reference to the project DLL, but that didn't work either. How can I use my own utilities like this?

I am trying to create an application to make self-extracting Exe's in Visual Studio 2010 Express. I would like to have a box in which files can be dropped into, then when you click "Compile" it will compress all files dropped into the box along with 3 others I must have delivered to this self-extracting exe. When the newly created exe is run, it will launch "Install.exe". I know there are other items out there to build the self-extracting exe's. I would however like to make my own that always delivers these 3 specific files along with whatever is dropped into the application.

I want to find the framework class that enables one to choose an image at design-time. I can find the editor that is used at run-time - its the Drawing.Design.ImageEditor. At design time, however, a different editor pops up which allows one to choose an image from resources.I'm guessing I could run some kind of program, then open up the image editor, from the property grid, and see what new windows/classes have been created?

It seems that in C#, a solution can contain multiple projects, which, I guess, would compile into separate but somehow related programs. It seems that this functionality is missing in VB, even though VB uses solution files as well.How would someone go about creating a tool or utility or "helper app" for a project? For example, a command line version of the program, which is a separate executable, but obviously would be distributed as part of the main program? Maybe I want to integrate a feature into windows where the user can right click on a certain file and choose "convert" from the context menu, where "convert" would open the helper app, which would read the file and save an updated copy of the file (converting from one file format to another and saving the result) without the user needing to wait for the main program to load, wait for the interface to be configured, then wait for the file conversion. The helper app would not need to display an interface to the user - just convert and save the file.

Background: I have read a bunch of techniques to handle compression. I don't think SmartZipLib handles 7z. System.OS.compression does not seem to handle rar or 7z. I am trying to find one approach for all.The tools within Windows XP seem to handle them all from inside the file manager (at least on my computer).Question: how can I decompress all these files using the windows utility? I am guessing it is some sort of Shell command. Alternatively, is there another option?
