Steps To Take For My Scenario Using WCF?
Mar 6, 2011I should start a project where several clients are included. There is a wcf web service controler that after a call from an specific client about a certain question it will retrive data from a server in London and then it will pass it back to the corresponding client in a different country e.g.
Clients and service are far away. the only way of transportation is through HTTP and intenet connection. Service should be able to callback also so i guess it will be dualHttpBinding.
How To Approach Scenario / Approve Changes
Apr 11, 2010I'm working on a system where there can be 2 level of users "Admin" or "Researcher".We have the requirement to allow the researcher to change fields for a record a record, but they want the original values to stay in the record and have an admin "accept" or "approve" the changes before the real record gets updated.Has anyone run into this scenario before? I'm trying to think of the best way to do this.
View 3 RepliesWrite Pseudocode/algorithm For A Scenario?
Apr 21, 2010I have a class exercise that I need to do by next week. The problem is that I don't know how to write it.What I have to do is write pseudocode/algorithm for a scenario.I understand that I need to use a 5 step process for it but I don't know how to turn it into pseudocode.This is the scenario (there are 3 from memory that I need to do this is just one)"you want to estimate the number of hours it will take you to complete all of the levels in a new video game based on your past perfomance with other games."
I know I need to break it down into inputs, outputs and processes? I think that's right, but I'm struggling with writing it and getting it started.I don't need to use any actual code for the exercise. I just have to do the pseudocode and a flow chart for each scenario.

Asp.net - Session Variables Lost In A Specific Scenario?
Dec 23, 2009I've got a problem losing session variables in an ASP/VB.NET application. The application allows searching for an item or it can show an item if provided with a unique link (in the browser). It holds information about the item in session variables. In the webpage showing an Item a user can click a button which opens a window with additional information about the item - obtained from a session variable. When I search for the item using the search engine and click the button - it works OK.
When I copy the link to a browser: the item is shown, however clicking the button returns a 'null exception' - the session variables with information about the item are lost. Moreover when I provide the link for the second time the button works, the variables are there!
User Create Template / Configuration File For Application That Can Be Used For Different Scenario's?
Aug 13, 2011I have an application that I'm writing that needs to allow the user to be able to create templates and save them for how the applicaton will work. For instance, lets say I am provisioining mobile devices, and my application allows the user to create a template to only install "application1" on the device, with "application1" settings for "devicetype1". But then if the user has "devicetype2", he or she can select the template that they created to install the software for that kind of device. I've looked around and all I find is the .exe.config for read only application settings, and I have found the user.config for the read/write variables. But that won't work as my application could have several templates depending on what the user chooses. I'm looking to have my app have a "create template", "edit existing template, and"use existing template" buttons, and have my config file extension like *.ipx for example.

Jul 5, 2009why my code isn't deleting the selected row in my ListView from my SQL table? it says it works fine in run time and removes the seleced row from the ListView but when i restart the program its there again.

.net - Excel Data Export Fixing Number Errors/removing Green Triangles
Aug 8, 2011After exporting data using a third party component the data in the excel sheet isn't type correctly. Excel thinks that some values are string while they are numbers and a little green triangle shows up.
We've coded the following to fix this:
For Each objCell As Microsoft.Office.Interop.Excel.Range In objWorkSheetReport.Range(objWorkSheetReport.Cells(1, 1), objWorkSheetReport.Cells(Me.RowCount + 10, Columns.Count + 10)).Cells
[Code].....
This removes all those little green triangles but is really slow.
Is there a faster way to convert a Range of data quickly so the green triangles don't show up?
Avoid Create/drop Table Scenario With A Perm Stage Table?
May 10, 2010I created a function that creates a global temporary table to stage data from a excel sheet I need the table to persist for me to map the columns using a form. The table is still there when the code goes back to the sub that calls the function until I call the form where I do the mapping. I am trying to avoid create/drop table scenario with a perm stage table.How can I get this table to persist until the data gets loaded into the perm table?
View 8 RepliesError - Scenario: Printing - 6 Different Things To Print Including "Permit" And "Permit Copies"
Mar 19, 2009I'm a little baffled why I get this error. Scenario: Printing - 6 different things to print including "Permit" and "Permit Copies". "Permit" looks like a drivers license including a photo."Permit Copies" is exactly the same except it has a piece of text at the bottom that says "Sheriffs Copy".
The problem is when trying to print "Permit Copies". Very few of them shows the print preview - most just display the FileNotFoundException error. If "Permit" pulls up the photo just fine, why not "Permit Copies?" It should be trying to pull up the same photo as "Permit" - same file path/name. Where is it wrong in my code?

View 5 RepliesRemoving Last Line In RTB If Next One Is Same
Aug 26, 2010I am still very new to VB. I am having trouble working out how to remove lines within a rich text box, based on the next new entry into the rich text box.
For example:
rtbClient (the rich text box) already has the lines:
long cat is long
he really is
long cat is long
Now, if the next NEW entry into the rich text box is "long cat is long", then the new "long cat is long" string would be ignored because the line previous (and only the previous line and not all lines that already exist) is exactly the same. Note, I know of the Me.rtbclient.Lines = Me.rtbclient.Lines.Distinct.ToArray code, iv tried playing around with it with no luck.
Removing Last Row Datagridview?
Dec 11, 2008Okay I have an unbound DataGridView control which users enter as many records as is required. However I have some validation running which checks all cells to ensure data has been entered, however as you know, as soon as data is entered into a row, another appears, well I need to remove this row.
I can't use
vb
DataGridView1.Rows.RemoveAt(DataGridView1.Rows.Count - 1)
As the row has not been committed, therefore it can't be deleted
Also I need the 'enable adding' on, as without it rows will not appears.
Removing The Zero From Text Box?
Jul 22, 2011I can't get a zero into a text-box, what I'd like to achieve is this: if the textbox is zero, then I want it to remain as a blank, until I enter value to that field.Actually When I activate the field via some other control, then I Never wants to display "0" zero in Textbox Fields, before operation done.

Unit_Price=0 or some time it have default value, i.e. 25, which display ok, but not the below field.
Unit_on_Order=0

Event Handler Not Removing Itself?
Jul 5, 2010At the beginning of a VB .NET function I remove an event handler and add it again at the end of the function because the function's code would trigger those events and I do not want them to trigger for the duration of the function. This usually works, but I have run into a few situations where the event still gets called even though I have already removed it. Sometimes removing it twice at the beginning of the function fixes it, but other times no matter how many times I remove it, it still fires.
Edit:The code is in a Form that has a virtual mode datagridview. I want to run some operations that will trigger the CellValueNeeded event for the datagridview without that event being fired (because it will interfere).
Public Sub DoEventRaisingStuff()
RemoveHandler grid.CellValueNeeded, AddressOf grid_CellValueNeeded
'Do things that would trigger CellValueNeeded
AddHandler grid.CellValueNeeded, AddressOf grid_CellValueNeeded
End Sub
Removing the handler multiple times does not prevent the event from firing, so it doesn't seem to be added multiple times somewhere else by accident.Is there a way to find out what event handlers are active?

Removing A Delimiter From The End Of A List?
Jun 28, 2009I've been working on this program all week and I've been able to finally get it to work except for one problem. The program is suppose to parse strings from a text box to a list box and then from a list box to a text box using the users choice of delimiters. I can't seem to figure out how to get the last comma off the end of the list. ie cat,dog,elf,It seems it should be easy, but since I've worked on this program so long I believe I can't see the forest for the trees. I don't want for you to do my work for me.
