In my game, there are many chapters that the character plays through. I want a savefiledialog to save to a folder (OF my choice) and then have another dialog in the main menu that can read exactly what chapter that save file was and then start the user at that chapter. What I need to know is A) How to assign a savefile with properties such as the Chapter name and B) How to save/load files with the savefile dialog

so i have a quite huge program. but lets say i have one label. and i want to save that. i have the code and everything for saving the text of the label. now i want to assign ctrl+s to automatically save the labels text once pressed instead of going through a menu to choose save.this is like a regular texteditor where u press ctrl+s and it saves.
ive used this
If (e.KeyCode = e.Control & Keys.S) Then
MessageBox.Show("Ctrl+S pressed")
End If
and
[code]....
but it doesn't do anything once pressed.im also using the keydown declaration for the form.
I need to have a property that is a nullable date as the datestamp is used for when a process is completed. If there is no date this is a way to determine if the process has occurred. I have created a Nuallable DateTime property (DateTime?) However when I try to assign a value from my database entity (when debugged has a date value) I am not thrown an exception however my property still reads a null value after assignment. How can I get a DateTime? type to accept a DateTime value?
I thought this would do the trick
_object.DateStamp (type = DateTime?) =
_entity.DateStamp (Type = DateTime?, Value = DateTime) o
Or for more understandable syntax
Ctype(object.DateStamp, DateTime?) = Ctype(entity.DateStamp, DateTime?)
Strange thing is I can assign the properties value like this.
Ctype(object.DateStamp, DateTime?) = Now
I am using LinQ Entities.
i would like to assign my array vals to properties of my object.
like:
For i = 1 To 32
myClass.Prop_i = val[i]

In VBA / VB.NET you can assign Excel range values to an array for faster access / manipulation. Is there a way to efficiently assign other cell properties (e.g., top, left, width, height) to an array? I.e., I'd like to do something like: Dim cellTops As Variant : cellTops = Application.ActiveSheet.UsedRange.Top..The code is part of a routine to programmatically check whether an image overlaps cells that are used in a workbook. My current method of iterating over the cells in the UsedRange is slow since it requires repeatedly polling for the top / left / width / height of the cells.I'm going to go ahead an accept Doug's answer as it does indeed work faster than naive iteration. In the end, I found that a non-naive iteration works faster for my purposes of detecting controls that overlap content-filled cells. The steps are basically:
(1) Find the interesting set of rows in the used range by looking at the tops and heights of the first cell in each row (my understanding is that all the cells in the row must have the same top and height, but not left and width)
(2) Iterate over the cells in the interesting rows and perform overlap detection using only the left and right positions of the cells.[code]

The problem is that if I save a file I get "myfile.GDL" if I overwrite that I get a new file "myfile.GDL.GDL" ect.the other problem being that the filtering in the windows save/open dialog wont show .GDL files unless I select "all files".
I have used the following code too save a notepad file; [Code] The code saves files but only in the 'Application.StartupPath' folder, the save dialogue starts in the correct place a quizzes folder inside the debug folder but files can't be saved here or in folders inside it, even though you can browse them in the dialogue. I want it saving where navigated to in the dialogue.
View 2 RepliesI've been programming in VB6 for years, I have decided to take the plunge into VB.net and C# 2010 but having a little problem understanding the big picture.In VB6 I could create user controls and save them as .ocx files, then use those .ocx's in other programs or on html pages. I am sure the same idea is present in VS 2010, I'm just not seeing it.Can anyone recommend a book or tutorial that will show me the big picture of all the aspects of the .net environment?

View 8 RepliesIn the form design I set up a TableLayoutPanel, 20x20 cells and in cell (1,1) a PictureBox (called Target) containing the image of a small target. The properties box for Target shows some very promising properties, Column and Row - and if you overwrite the values in the properties box, the PictureBox obligingly shifts to the corresponding cell position in th design. However in VB it is not possible to refer to Me.Target.Row or .Column - neither appears during coding in the menu of properties, and deliberately coding either of them produces an error like
Error 1 'row' is not a member of 'System.Windows.Forms.PictureBox'.
1. Why does the properties box show properties that cannot be altered programmatically?
2. How can my program move Target around in the TableLayoutPanel?

I want to develop an application which can Write, Save, Read text files(or html files) What I want the application to do is. When I open my application I can write stuffs and then it will save it to my hosting/server. Then, the application will read the text which I already save.. So far, I can only make the application read it by using WebBrowser control and navigating it to a specified URL. Example: [URL](or message.txt) Which I modified from the website not from the application. I want to modify the text or html files from my application.
View 6 RepliesI found that there was the Settings.Properties collection as well as the Settings.PropertyValues collection, and hopefully i'm not doing extra work here, but i'm creating both, and then assigning a value to the Settings(PropName).
Defaultly, in my "static" settings (through the IDE designer window and such) I have 9 settings/properties, and at run time when I'm processing, the Settings.Properties.Count doeos indeed equal 9.
Now, in the process of my application I generate some "saved" control properties myself, and actively "add" them to the Settings:
For Each prop As String In Me.Keys
Try
name = Layout & "." & _control.Name & "." & prop
[Code]....
This seems to work fine, and after the repetitive code (cycling through a collection) is finished, the Setting.Properties.Count does indeed equal 79, for the 70 new properties added.
I not only execute a My.Settings.Save() when the application exits, but I know I also have the SaveMySettingsOnExit set to true, but the next time i load up the app, my settings.properties.count is back to 9.
I put a PropertyGrid control and set the control to be a button on my form and i run it and change some properties and reflected on the button but when i restart the application nothing is saved so i have to save it to the disk like serialize the control is this the right thing?
