I need to save the controls location and size on the parent form to file. My aim is to be able to simply copy that file to the path where an instance of my program is running and then it automatically applies the previously saved layout of controls. How can I use My.Settings to do that or is there another better option?
View 12 RepliesAfter a little research, I managed to get a working Help button added to my form. I did this by setting the MinimizeBox and MaximizeBox properties of the form to false, set the ShowHelp property of the form to true and added a HelpProvider component. I then added a string to each control's HelpString property that I want to display help on.
Everything works with one minor exception. When I clcik the help button in the form and then select a control, the HelpString (tooltip) is displayed in the far lower left corner of the screen. I assumed I would see this pop up at the cursor rather than where it is. I cannot seem to find a property to control the position of the HelpString popup.
How can I get x and y coordinates of a control's location on a form relative to the Screens Top Left corner?
For example, if I have 3 labels on a form and I want label2 and label3 to display the x and y of label1 relative to the screens top and left corner.
When running the app, as the form's possition is changed label 2 and 3 update the coordinate of Label1's possition relative to the top left of the screen.
I have a control on a form - I need to know the coordinates of that control relative to the FORM.
Now before I get six replies saying, "Control.Location DUH!!" that only works when the control's parent IS the form. What if the control is nested inside one or more container controls?
Could I write a routine that crawls up all parent containers until I reach the form calculating each offset as I go? Sure! But this extremely crude operation seems clunky to me - What I'm looking for is something a little cleaner.
So far the closest I've been able to come is this:
Dim ClientPoint As Point = Ctrl.PointToScreen(Ctrl.Location)
Dim LocationLeft As Integer = (ClientPoint.X - Ctrl.ParentForm.Left) - Ctrl.Left
Dim LocationTop As Integer = (ClientPoint.Y - Ctrl.ParentForm.Top) - Ctrl.Top
The problem with the above code is: It does NOT take the Form's border or Titlebar into consideration... so this calculated location would be off slightly depending on what kind of border the form has.

I'm working with Visual Basic 2008 Express. My application opens with the Terms screen, a form that asks the user to declare his acceptance of certain terms and conditions or to decline. If he accepts, the app opens the main screen, giving him access to all the app's facilities. If he declines, the app gives him a message and then closes. Whether he chooses to accept or decline, the app puts his decision in My.Settings so that it can be used next time the app is opened. In this way he is presented with the Terms screen on the next opening if he declined on the last run. But if he accepted on the last run, he is presented with the main screen on his next opening.
All works fine when I do a debug run. But when I build and publish the app onto my desktop it opens with the Main screen instead of the Terms screen.
why it works on F5 but not after publishing?

I need to very quickly write an exe system on a laptop where when the laptops are connected to the network they read a database table and store the data locally, so staff can use the laptop while they roam.The laptops have quite small capacity and the company would prefer not to use SQL Express or Access.
My question is, can the data initially be downloaded into the exe application via a dataadapter and dataset, and will that dataset the retain the downloaded data, or will I need to ensure the dataset is written to an XML file and then loaded/unloaded each time the laptop application is started while the staff are travelling ?

View 1 RepliesI am developing a windows app in VS2008 to be used along side ESRI�s ArcMap. Most ArcMap users will have dual monitors and I would like the user to be able to choose which monitor my app is loaded on to.
When I deploy the app using the standard install package, the app will load onto which ever monitor the user places the desktop shortcut. However, when using the ClickOnce method of deployment, the placement of the shortcut does not matter and the app always loads on the primary display monitor.
Is there a way to control where an app is loaded by code or any other method?

I have a picturebox (pbRows) that I want to always be aligned with the right side of the screen. The form may be wider than this (I have a horizontal scrollbar), but the picturebox always needs to be along the right edge of the screen. Currently I have this code snippet in the form_load subroutine:
Dim rowsX As New Integer rowsX = Screen.PrimaryScreen.Bounds.Width - pbRows.Width pbRows.Location = New Point(rowsX, 25) However, the picturebox is aligned with the right edge of the form (initially hidden off the screen). Am I missing something obvious?
I have been searching for quite a while now but i am unable to find the answer to the following. I am storing a key pair in Windows Store, and recently started receiving the "Keyset does not exist" error. Investigating a bit further i found out it could be two things, 1 - The private key is not stored with the persist key set attribute (X509KeyStorageFlags.PersistKeySet) and 2 - access rights to the key. I have tried both 1 and 2 with no success on one machine (in my machine it works apparently). The strange thing is that when i look into MicrosoftCryptoRSAMachineKeys (and S-1-5-18) the key remains there but only for a period of time then it is deleted which means that it is not persisting.
//If decoded then save as RSACryptoServiceProvider
newCert.PrivateKey = DecodePrivateKey(privateKeyFile, pkPassword)
if (newCert.PrivateKey == null)
[Code]....
I have just found out today that since i am doing this through a WCF service, the application pool is deleting the private key when it reaches its idle time limit so i am completely sure that it is the application pool the one disposing of the private key which causes the key to be deleted from the MicrosoftCryptoRSAMachineKeys and S-1-5-18 folders. Today i left a test running where i disabled Idle time shut down from the application pool bu i am still not sure if the private key will stop persisting with a restart or something like that?
Would anybody know how to make the application pool stop deleting my private keys?
I need some general advice about using ListView. The program was originally written in VB2002, but now it's running in VB2008.The results of my program would typically be a ListView of 30 lines by 8 columns. I need to be able to save this data so that it persists after I close the program. There will never be a need to manipulate the data, so I'm looking for something simple. (There will be a need to print it.) I'm presuming that I need to link to a database to save the data. Correct? If so, can I use the one in Microsoft Works (which I already have), or do I need to get Microsoft Access, or is there some other better (simpler?) alternative?

View 2 RepliesInstinctively, I would say that this is impossible, as NHibernate needs to know some mapping information on how to persist a given type. Thus, I encountered some situations in which I could use such a feature. For instance, through a named query or something like so. On the other hand, using a named query would require me to make an addition to the configuration file.
Let's suppose we have an application interacting with some underlying datastore. This datastore is configured through the NHibernate configuration file. Then, I wish to have NHibernate load only a subset of an entity properties, from another subsystem to which my application shouldn't need to interact much, so it is not worthy to define classes for this system, as I only need a fraction of this alien system's information, let's say three out of thirty-two data columns. For that matter, if I chose to load only those three columns let's say for performance concerns, I would then use an anonymous type, perform the required action onto this information, then persist it back to the datastore. Now, it wouldn't be of much interest to do so if I only had one entity to get loaded from the datastore, so let's say I have about 75,000 rows to load into my process. I then shall consider this subset option very seriously!
What strategy should you choose in such situation, if you needed to persist these changes to a subset only of this entity's properties?FYI: I am asking because I must write specific rules of usage with NHibernate, such rules that even a beginner developer would even be able to use it without knowing too much about NHibernate, but only following the rules and guidance of the technical documents I have to produce.
