View 1 RepliesI have a simple desktop application that uses a .NET setup project (.msi file) to perform the installation. On the first installation, everything proceeds in a timely fashion with good feedback for the user.The problem occurs when the user is installing the latest version of the application over an old version on their machine.There is an unacceptably long delay of about 60 to 180 seconds from the time the installer's 'Welcome' dialog [It's not the Welcome dialog, I've removed that from the Start section of the setup project and replaced it with a CheckBox dialog to ask if the user wants a shortcut on the desktop] disappears until the 'Progress' dialog appears. The user sees minute(s) of blank screen and thinks the install has stopped or failed.
In the setup project properties, I've got the 'DetectNewerInstalledVersion' and 'RemovePreviousVersions' properties set to true. So, I believe that while nothing appears to be happening, the installer is actually removing the old version. The 'Progress' dialog does not appear until the new version begins installation.I've been trying to either:
a) Get the 'Progress' dialog to display immediately after the 'Install Icon' dialog disappears
b) Show another dialog while the Uninstall is running to let the user know that the setup is still running and everything is OK.
I have been unsuccessful with both methods. I'm using VS 2008 SP1?
I have a VB.Net interface that communicates with an Access 2k3 Database using this module:

Can I create new dialog results for my dialog forms? And then use them with Form.ShowDialog method?
View 13 RepliesIs there a way to launch a Modeless Dialog that stays active even when a Modal Dialog is launched? Can I put the Modeless Dialog in a seperate Thread or something like that?
View 3 RepliesI often use the process of displaying a dialog from a form, with the dialog user input then used to update the main form without any problem. In a new scenerio I launch the main application screen, I then show a login dialog ontop of the main app screen and can launch another dialog from the login if a new user is required. The plan is to update the login dialog (updating a combobox to reflect the addition of a new user) from the new user dialog.
See code below :-
'Update login forms user list as new user added successfully
frmRoomBookingLogin.cboLogin.DataSource = Nothing
frmRoomBookingLogin.txtPassword.Text = "Updating password from dialog"
MessageBox.Show("The password text is " & frmRoomBookingLogin.txtPassword.Text)
[code]....
The messagebox implies the dialog has been updated yet the text does not change. Is it possible to update the dialog when using a setup such as Form -> dialog -> dialog? I'm intrigued as why the dialog does not reflect changes. I have never refreshed/repainted the dialog as never required to in my other examples when updating a form from a dialog and never encountered a problem when using a two tier form setup.
I have an assignment due this week in which I have to make a app that has 5 buttons and a picture box. When each button is clicked it has to show the corresponding picture in the picture box, the fifth button closes the app.
I have the whole form set up the way it should be, but I have no idea how to write the code to make the buttons display the images and close the app.I have the images in a folder within the project folders.
I have yet to be able to find one, the one I found should how to do it using a file opener dialog and a folder browser dialog but that is not what I think my prof wants us to do, as that is more for a picture viewer app that lets the user choose the file of the image they want ot view.
All i want is for the buttons to be linked to specific photos that are part of the application itself and have them open.

View 12 RepliesI have a Dialog that is basically a confirmation dialog on some SQL statements. After the dialog I have an if statement: If frmRelease.ShowDialog() <> Windows.Forms.DialogResult.Cancel then.My buttons are set as DialogResult = OK and DialogResult = Cancel respectively on the dialog form.
For some reason, sometimes my button set to DialogResult = OK is returning me a DialogResult.Cancel, and causing me to skip a block of cleanup code.
I'm using a DLL in vb.net 2005, and this dll show a messagebox with OK option. I would like to close this Messagebox by code.
I was investigating to use SetWindowsHookEx, but I can not detect it. Is it possible to don't show any dialog, or detect the dialog using the dll name?
I have a dialog which opens another dialog. The problem is that the second dialog opens behind the first. Is there a way to stop this from happening? I tried bringtofront with no success.
View 2 RepliesI have a problem when trying to send a POST request. The sending method looks like this:
Public Sub SendXML(ByVal file As String)
Dim reader As New StreamReader(file)
Dim data As String = reader.ReadToEnd()
[Code]....
Now looking at this I suspected that it was due to the fact that the server does not accept POST messages. But some other reading suggests that the the URI [URL] has been generated with a proxy and should be /Request so the line should read POST /Request HTTP/1.1
So what would be the common reason for this? And if it is a proxy problem, how is it sorted?
As asked below, I have created a new question for the more specific request. Changing absolute URI to relative in HTTP POST header
I know that you cannot specify a constructor in an interface in .Net, but why can we not?
It would be really useful for my current project to be able to specify that an 'engine' must be passed in with the constructor, but as I cant, I have to suffice with an XML comment on the class.
are nested functions allowed in visual basic?
View 9 Repliesi am currently having two problems with this assignment. The program allows the user to add new students to a listbox with a unique Id, lastname and test average. When adding a new student to the listbox, part of the assignment is to not have duplicate students added. I am currently stuck at trying to figure that out. I have figured out how not to have duplicate courses under the course information form but when trying similar code for adding a student i cant get anything i try to work. the next problem is when searching for a student from the list and clicking on the Course Information button, the course information added for that student needs to be displayed. My problem is getting the student searched information to show up right, but if i add three students and search for the first one i added and click on course information button it only shows the last student i added. this is my code for the whole program

I am assuming "No", but I cannot find conclusive proof on Google to back this assumption. Using keywords of 'vb.net "generic operator overload"' yields exactly 1 result, and removing 'overload' gives more, but no direct statement to the issue.
My thinking is given an abstract class, it'd be great to be able to implement a generic operator overload that a derived class can use in such a case when said operator overload has to return a New copy of the derived class, yet the code for each overload is the same. If that makes any sense.
This touches back to my previous questions on my custom Enum class and overloading the bitwise operators (And, Or, Not, & Xor), but, this particular thought was prompted by a mere curiosity of "Can it be done?".
Here's what one of my custom enums basically look like:
The parent, EBase is nothing special, just hosting common Name and Value properties, plus two shared operators, op_Equality and op_Inequality.
Friend NotInheritable Class EExample
Inherits EBase
Private Sub New()
[Code]....
Then (in theory anyways), calling EExample.OneA Or EExample.FiveE would work because the compiler would know to call the generic operator overload from EBase, know that EExample.Enums matches the IEnums interface constraint, and automatically supply T.
That or I'm just swimming up a certain creek here without a paddle and over-analyzing things. But it's an interesting thought, no? What is StackOverflow's consensus? Do I need to lay off the Spice a little bit?
PS: I use /* */ style comments because Markdown doesn't handle VB-style properly.
PPS: I know that, in the last example, Return New T( ... ) is invalid, but I can't think of a proper syntax that would articulate the basic idea.
How can I check for characters not allowed for file creation programmatically? you know like the / <> and so.

View 7 RepliesI am using an ADODB connection to a Sybase ASE Database for a small app that runs queries and returns the results to a grid, to XML and to Schema file. I recently tried the query on a Sybase script (Between a Begin and End statement) and had an exception when I used RS.EOF which reported "Operation is not allowed when the object is closed." The code works fine for other queries, including those between begin and end statements, so I did some debugging and found that the failure only happens when my SQL script (Which is typed into a rich text box) contains either Sybase variables (ex. @MyTable) or uses temp tables (ex. Select * into #mytemptable from myrealtable). The actual execution works OK (without an exception) but the recordset seems to be closed. A failing example is :
Begin
Declare @Name Varchar(30)
Select @Name = "MY_TABLE"
