I'm creating an application software. It has many features, which is in the base version of the software. And people could buy my software (which will be enough for most of them since it had all the common features needed) and use it. But some of them might need additional features to this version.So, I can add new features to the base version of my product and provide them a custom or extended version.
But my question is, how can I effectively manage these versions of the software while updating (or upgrading with new features which are common to all of them)
[Code]...
In the above example F1, F2, F3, F4 & F5 are the features available common for all editions of my software.Whereas, A1, A2, A3 & A4 are the additional features added based on customer's request.
I need to replace something that's going to change in the future and I don't know what that's going to be, so is that possible? I'm talking about Flash Player, current version is 11.1.102.55 and I can replace that with nothing, but if that version is changed my text replace wont work. I have one empty space after flashVer=WIN 11,1,102,55. Textbox1.Text = Textbox1.Text.Replace("flashVer=WIN 11,1,102,55", "")
how to disable the datetimepicker dates in the future and also all the weekend dates but i am unable to find any! Only thing i can find is ASP.net code.
I have an issue with Visual Studio's support for coloring User Types in VB.NET, I'm an C# developer that have been forced to code in Vb.NET by political rules in my organization, and I really misses the support for coloring user types in Vb.NET, I had hoped that this would be solved in Visual Studio 2010 and well in the beta they have added Vb.NET User Type coloring, but the coloring is the same for all user types I cant't have one color for interfaces and one for classes and so on.
I need to navigate to a webpage and copy a string of information from it within the shortest possible timeframe. The site has the following written on it:This is the string that you need to apply to your algorithm.
Generated String: 61*76*83*47*69*88*
I want to copy the string from the webbrowser control and place it into a string called "GenString"
i m doing a project using vb .net visual studio2005 . i need to develop a online chat application on my website for customer care supports. where i should start and which technology i should use for this web based application..
I have my program set up to download a web page with a webclient. Normally, I could just use .Substring, but there are about 25 things I need to pluck out of this page, and .Substring, or at least the way I have it set up, takes the first occurrence. The good news is, they are all URLs; they are all similar too.
Each URL is as follows: [URL]
Now, of course, this URL is just made up, but each URL starts with [URL] and ends with 'video'.
How can I hook this up so that it scans the entire page (contained in a string, read from a StreamReader connected to a WebClient), finds each URL, and then adds it to a listview?
So far, I have always run applications within the IDE, using Debug Mode.If I publish an application will I have to add code to repaint Picture Box graphics?In the IDE, my Picture Box graphics never get disturbed by running some other application or minimizing my forms.
I have noticed some discussions which suggest that code is needed in the Paint Event Handler in order to redraw graphics which disappear due to minimizing the form or running another application which displays a window covering my application.
I want to be able to drag data from one DGV to another. When the drag is completed, I want the backcolor of the cell that the data was taken from to change to red. I will add a "trash" icon that will accept a drag and drop from the 2nd DGV to remove the data from its respective cell. Finally, when the cell is trashed, the corresponding cell from the first DGV will return to it's normal backcolor. My application is going to be used to schedule clients with employees for a home health care business. The reason I want all of this is so the user has a visual aid to show them that times have been used already to avoid double staffing. i also have to figure out how make all of this unique to each client when flipping through the DGV/binding source.
For instance, I read that visual basic .net didn't have operator overloads before, so wouldn't be able to use a types overloaded operators, if they aren't provided as normal methods too (Add, instead of operator+).
I've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.
Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.
Imports System.Data.OleDb Public Class Form2 Dim Conn As OleDbConnection [code]...

I know the WOW environment is currently shipping on Windows 7 and 2003/2008 MS server products to enable the use of 32-bit applications. But does anyone have any thoughts on whether they are going to provide this environment on PC and server operating systems beyond Windows 7?
I know that the runtime files (DLL, etc.) will not be provided beyond Windows 7 for 32-bit VB 6.0 applications to run on.
I am performing a migration on a vb6 program, to vb.net. The basic knowledge you need to understand this question is that there are two forms that need to talk to each other, frmInput1 and frmInput2. I have the following code (behind frmInput1) that checks if a textbox on frmInput2 has a certain value, seemingly before it has loaded:
I'm using the ASP.Net Membership system but I'm having an issue with the LastActivityDate for the users in the database. For some users, their last activity date is in the future...
Create a project that determines the future value of an investment at a given interest rate for a given number of years. The formula for the calculation is Future value = Investment amount * (1 + Interest Rate)^ Years..Form- Use labeled text boxes for the amount of investment, the interest rate (as a decimal fraction), and the number of years the investment will be held. Display the future value in a text box formatted as currency. Include buttons for calculate, Clear, Print, and exit. Format all dollar amounts. Display a message to the user for nonnumeric or missing input data.Remember that the result of an exponentiation operation is a Double data type. Interest rate is annual.So far this is what I have and I am missing something(s) in the calculate process.[code]
I'm automating some outlook functionality in a .NET app. It works great. I am compiling it and using v 12.0.0.0 of the Outlook Interop assembly. My code should work on any version of Outlook so it seems silly to have to bind it to a specific version. Is it possible to use reflection to do this instead of compiling a reference? Are the interop assemblies on PC's by default that have Office installed anyway or do I need to include them with my application?
After right clicking on the form Context Menu give option to see 'View Code Window' which opens the the view code window and shows from the first line of code in the file, where actually it should show Event handlers related to the control on which Mouse was right clicked. right now we have to go through the line of codes to locate the event related to particular control.Also after double clicking on the control, VB inserts a default event handler to Code file which should happen only when there is no Event Handlers added for that control previously & if a previously added Event Handler present, double clicking controls should locate that procedure.[code]after dragging dataset table to the form vb assigns 'field name' concatinated with 'TextBox' to TextBox Control likewise 'field name' concatinated with 'ComboBox' for ComboBox Control where it is difficult to locate them in Controls Member list into code..Instead why don't you prefix them with 'txt' for TextBox, 'cbo' for ComboBox etc. It is then easy to find one in code. Or make the original Optional.
I have a form where a user can choose an election date. One of the most frequent errors users make is entering the incorrect due dates of reports. Therefore, I am attempting to generate the report due dates in the application using the report guidelines. For instance, reports are due 32 and 15 days prior to the election and 30 and 60 days after an election.
I know the following won't work but you get the jest of what I am attempting to do. I am assuming I will need to break down the month, day and year somehow before I subtract or add the days to the date to get the actual report date.
I need to save actual age (in whole years) for future use in the program. The problem is, 'Years' returns a big, fat 0 every time. Changing "Dim years As Integer" to Dim years As String" does exactly the same thing.
Code: Dim myDate = New Date(Convert.ToInt32(Year.Value), Month.SelectedIndex + 1, Convert.ToInt32(Day.Value)) 'If Month, Day, or Year not selected then
I need to have the Calendar Control start 36 hours after the current date. How would I do that?
I have a form that requires that the future date has to be at least 36 hours from the current date in the order for the workers involved to be able to complete the task.
check values and keep the form from processing:
Protected Sub calPickupDate_SelectionChanged(sender As Object, e As System.EventArgs) Handles calPickupDate.SelectionChanged If calPickupDate.SelectedDate < Today.AddHours(36) Then
I am at the stage of planning the application which will conect to a Ms SQl database, and process some data to Excel files.The problem is, that i would like to make a base pure application, without any functionality, and then add functionalities by adding some external files with code to program folder.I`not sure if what i just wrote is clear. To simplify:I would like to have an application which connects to a database, but let`s say when after 1 year, i will be in need of some more functionality, i woun`t have to change the code of whole application, but can just add a new file, and when I run the application there will be one more function to be chosen from the list.
I am trying to flag rows in a grid in the following order based on a date column
When 2 or more days old from today then RED When 1 day old then YELLOW When 0 days old then GREEN When the date is in the future then BLUE
I have the following which is working fine except for the future dates which are GREEN instead of BLUE.
Dim myDate As DateTime = CType(grdSummaryView.GetRowCellValue(e.RowHandle, "myDate"), DateTime) Select Case Now.Subtract(myDate).Days '2 or more days old then RED FLAG Case Is >= 2
I am teaching myself VB while creating a basic application I can use at work. Is there something in VB that will calculate a past and future date from a specific date. For instance, an Election Date falls on November 2, 2011. Once this election date is entered I want the program to calculate the reporting dates. The first report due is due exactly 32 days prior to the election. The 30 day post is due 30 days after the election.
I made a programme through which I get a feed back clicking a button for a future warning date. I am giving the code below so that you can givthe problem is, I have to take 12 DateTimePicker to do that job in a single form which is creating a saving problem means when I click save button it takes long time to save. Now, I thought If I can do it by using TextBoxn a date format would easeup my save problem. Or it can be MaskedTextBox as well. Below is my code if any one can give me the solution.
Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If DateTime.Now > DateTimePicker1.Value.AddYears(1).AddDays(1) Then
