I had an idea to embed a PDF document into my application somehow.The PDF is a copy of the user manual. I expect that the file will be around 20 KB. This way, if people don't distribute the PDF with my app, they can extract it whenever they need to.

View 1 RepliesI have built a MVC website on IIS6. I used the built-in ASP.NET Security without Membership, just the way it was implemented in the template solution. It is easy to secure a contoller or action, but now I need to expose the user management to an admin logged into the site. I understand that the builtin ASP controls for doing this are not "best practice" and are a dog to get working. So what is the best practice for offering user management through a ASP.NET MVC application?
I considered using the Entity Framework and wireing it up to the myriad of stored procs. but that seems awkward. I see options for AccountMembershipService and FormsAuthenticationService. That is what the existing project account controller uses. But, I am not fimilliar with either.I can't help but think that this should have already been there from the project template. This is a fundamental part of any website and you were given 15%, why not the rest?
I wish to build and display a simple diagram that is built from data entered by the user. Because I can't post a picture of the types of diagrams here I'll use the following example. Image a picture of a house as a child might draw it a large square, with a triangle for a roof, a rectangle for a door, and two smaller squares for windows. Now I want to build an application that lets the user enter data and change that drawing according. For example, by entering the length and height of the house the size changes, change the number of windows, size of the door or height of the roof.
Now this may seem like a useless application but keep in mind the house is just an example the real purpose is different but should be as simply drawn. I'm looking for suggestions on make this work. Should I use a paint? or is something like this better done with a tie into the Visio references?

View 4 RepliesI want my application to be able to communicate 2-way between the application on another computer and the host server which will be running on my computer.I want to use the BackgroundWorker built into vb to create a thing to make it listen for incoming messages, and also send out messages to the client.The client needs to listen and receive, same as the server, because both need to communicate with one another.I do not know how I can make it do either sending nor receiving.I would be using two different background workers to keep the code seperated and organized so that I will understand what code is for what.
I want the code to say that if i receive the message "Apple" without the "" and cap sensitive, then it will change Label1.Text = "That worked, word received Apple" or something similar to that. ( This is because I am ignorant and I want it to interpret the text sent through to figure out what the application is supposed to do, and last time I couldn't figure out how to make it do something when a certain text was received.
My code is basically a file parser/editor and it handles most files fine as they hold a handful of records concerning family members. However there are a few files that crash when trying to deal with them. Here is the problem.Each family member record creates 3 tabs that hold an average of 3 group boxes each. Each group box holds an average of 3 text boxes.So each member record creates 3x3x3 = 27 text boxes and some files get up to 289 family members which = 7803 text boxes.
The problem is the rare file with 400+ member records = 10,800 text boxes which causes a crash due to using up all the window handles. Each member has a separate tab page (with 3 subpages) but really only a dozen or so member pages are visible in the GUI with scroll arrows to move through them so I was thinking of somehow making the GUI a scrollable window so the tabs get built, displayed and disposed as the user scrolls left and right through the member tabs.
The files are parsed into a 3d list DataList(x,y,z) where x is the page number, y is the group box number and z is the text box number. So all the data is available. The code then traverses MyList and builds GuiList(x,y) where x is the page number and y is the groupbox number with all the textbox.text linked to MyList(x,y,z) locations so all text changes are reflected in the MyList.
I already have a memberCount variable and I am thinking of building, say, the first 30 member tabs with the middle 10 being visible in the GUI. If the selected tab > 20, then dispose of the first 10 tabs and create tabs 30-40.I am thinking I will keep all the member tab pages so I don't have to deal with inserts and indexing problems but just dispose all the group boxes and text boxes for tab pages out of view. I already have a deep clone sub that clones members when the user wants to add a new family member and I am thinking I will have to add something similar when a tabpage is passed in for disposal, it traverses and disposes each text box, then disposes the group box for each group box on the tab page.Additionally, another routine will rebuild the group boxes from the data held in MyList(x,y,z) when a tabpage(x) is passed in.
I have done research on how to manually create sorting in a grid-view and none of it is thorough enough for me to follow. I need more of a step by step solution, like what event should my sorting code go in, how would i enable the headers to allow sorting. normally, i just have .net do this but for some reason this time it doesn't allow it, maybe because i am not using a datasource.that's my code that creates a datable and then binds to the gridview.

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near and I don't know how does this happen because whenever I check the SQL that I have made including the inserted data, it shows no error.
View 2 RepliesI have my application set up with ClickOnce. It has been successfully published to my web site. I don't have updates performed automatically but on demand. I have a button that the user can click if they want to check if an update is available and install the update if it is. Here's the
[Code]...
After clicking the button a message box appears and says, "Update is available for download" as you would expect but after clicking the ok on the message box my application goes into a not responding state and I have to close it with the task manager. The application builds successfully and I have a reference for System.Deployment added to the project. Everything in my application works fine as long as I don't try to do an update. Any suggestions on what I should check or do? It should actually say "no updates are available for download" since the version of the program that is being used is the most current version.
If I turn off automatic updating of a binding data source by setting DataSourceUpdateMode = Never and then use a button to update the whole lot (using binding.WriteValue), a problem occurs - Namely, only the first bound control's data source is updated. All other controls are reset back to the original values.This is because when the current object changes (as happens after the above WriteValue), if ControlUpdateMode = OnPropertyChange, then all the other controls re-read in the value from the data source.
One way is to derive a class from BindingSource and add a WriteAllValues method.This method does the following:
(1) For each Binding, save the ControlUpdateMode
(2) For each Binding, set ControlUpdateMode = Never
(3) For each Binding, call the WriteValue Method
(4) For each Binding, reset ControlUpdateMode to the saved value
(5) For each Binding, if ControlUpdateMode = OnPropertyChange, call the ReadValue method.
If working with your own classes, would implementing IEditableObject resolve the issue?In another control I'm working on, I implement my own binding. The way I get around the issue in that is with the following code. (I've put in the bare minimum, I hope you can follow it!):
Private Shared ControlDoingExplicitUpdate As MyCustomControl = Nothing
Private Sub UpdateDataSourceFromControl(ByVal item As Object, ByVal propertyName As String, ByVal value As Object)
Dim p As PropertyDescriptor = Me.props(propertyName)
[code]....
So, when UpdateDataSourceFromControl is called, all the CurrentItemChanged events will be called for all other controls in the same BindingSource. However, because ControlDoingExplicitUpdate is set, they will not re-read in the value from the data source unless they happen to be the control that did the updating.ControlDoingExplicitUpdate is set to Nothing after all these events have completed, so that normal service resumes.

My column layout would look like this:[code]some one please explain to me how i would do something like this. if you can include the datatable definitions also it would be a big help, in order for me to verify that i am at least doing that the right way.

trying to automate some manual tasks. The task to access a web page (asp) login and then get some details from the site. The challenge is that the home page after login is build of 3 frames. when i see the page view source from the edit menu all i see are frame names. Once i right click on each frame and view source i am able to see the complete source - variables javascript function etc. The following code helps me to navigate :

Set ie = CreateObject("internetexplorer.Application")
Dim s As String[code]....
After this the page has been logged in. Now to proceed further i have to click a "image" object.
1) I tried qualifying the image like ie.Document..........item("img1").click this doesn't work
2) I tried calling the javascript function directly
ie.Document.all.Item("frame1").Document.parentwindow.execScript "JS_WGorUsers (funcname)", "javascript"
The 1st option gives a run time error and 2nd option says access denied. (if i login manually i am able to click the image.

View 3 RepliesI am looking to download several files from several FTP sites. Most of the time these files are all present by 08:00, but occasionally they are not there until a little later.Currently we have a bunch of excel sheets where the user goes into each and clicks a button which connects to the relevent ftp sites and downloads the files, performs some manipulation on them and then reports back to the user if the files exist, are empty, or if all is well.I am looking to redesign this, and was thinking I would encompass this within a Windows service which would have some sort of timer functionality which would start at about 7am, and end when all the files were downloaded whereby it would 'sleep' till the next business day.On the task completion it would send an email giving the information that was present in the current excel spereadsheets.
One thing with this is how often to poll the ftp sites to see if the files are there. I would ideally like to poll about once every 15 minutes or 1/2 hour, but if the user knows the file is present then they want to be able to invoke my process.One way of accomplishing this was to make the service a WCF windows service, so that it would run normally, and then if the user sends a request for amanual override, then the service would ignore its timer and run the process then an there.

View 1 RepliesI am using the NPV() function in VB.NET to get NPV for a set of cash flows. However, the result of NPV() is not consistent with my results performing the calculation manually (nor the Investopedia NPV calc... which matches my manual results)
My correct manual results and the NPV() results are close, within 5%.. but not the same...
Manually, using the NPV formula:

The manual result is stored in RunningTotal

I have an explorer-like interface which in many ways mimiques the behaviour of a standard explorer window. What I need is to find some way of knowing if something had changed in the filesystem since the last time I checked.What I mean, for example if a user creates a directory or renames a file - I need a way to know that. Right now I re-read the contents of the displayed folder once per second and I added a manual 'Refresh' button, but I wonder if there is a better solution.I tried to use FileSystemWatcher component for that but either I couldn't figure out how it works or it doesn't have such functionality.

I am not a .net programmer but I can write bits and pieces that I need, however, I have been having trouble working out the best way to achieve something for a website I'm altering.I basically need to have a drop down list which is bound to a certain SQL call (already in place) but I also need the ability to manually type into the drop down list for items that do not exist. These items do not need to be entered into the SQL (I can handle the additional data separately) but I cannot find a way to type inside a drop down list while it is bound to a datasource.Some entries in the datasource (SQL table) are used for one thing, but then a text string needs to be entered for optional entries which do not exist within this SQL table.
Does anyone know how I can achieve this or maybe another similar control can be used that offers this kind of functionality?**Update to be more clear:I need this at runtime. For instance, I do not need this to be within code I actually need the control to accept user input when someone is on the webpate.Imagine a shopping list and all the items are within the drop down list then the user wants to add another item to the shopping list so they just type it into the drop down box and submit the page and its value will be used instead of an existing item.
When I place data into the list box, I would like the new information to be visible at the bottom of the list without having to have the user use the scroll bar to see it. The data should scroll up automatically as new data is placed into the listbox. Can this be done?
