Passing User Object To Remote Server
Oct 9, 2011
I want to make a button like this:The first image is a normal button, but the second is a button with mouseEnter event fired. The bottom part of the button in the second image is not clickable and it acts like a tool tip. How can I make this kind of a button? Do I need to use a tool tip? Please give me some code examples.
EDIT:Here's F Ruffel's code which I modified:
[code]...
Now the last problem is: the expanded part pushes all controls down, and that's what I don't want. Please modify this code to make the extended part overlay controls that are below it, just like in the image.

My project uses .NET remoting. The client connects to the server hosted in IIS to do database operations.
We have a class library that is referenced both by the client and the server. This contains basic static (shared) functions used throughout the project. An example would be a function that takes a customer/invoice number and pads it with zeros/spaces to our desired format. This works fine. There is a copy of the dll with the client and on the server in the IIS virtual directory. Both the server and the client can call these functions and they work correctly.
Now, in that same class library, I've defined two things: an enumeration (enum) and a serializable class. If I try to call a function on the server from the client that passes/returns an instance of either the enumeration or the class, I get the following

I am having some difficulty getting my head around passing objects between forms and hoped someone might put me on the right track... I have five forms: frmMain, frmLogin, rmAdminMode, frmUserMode, frmUserMode, frmUserModeDeepThere are two main use-cases: admin mode and user mode.Admin Mode: As the project starts it runs frmMain. Clicking a button stops the autologin (simple timer) and will invoke frmLogin (using .ShowDialog). The user is prompted for the users' ID number (four digits) and pass-code (again four digits).frmLogin will query a back-end database to authorise or reject the login attempt (this bit is all working fine) and then return control to frmMain. If the user is a valid admin frmMain will then invoke frmAdminMode.
frmMain -> frmLogin
<- frmLogin
-> frmAdminMode

Question: How to pass the current user on the web page from the IIS server to the Reporting Services Server.I have seen this topic throughout the forums. However, the answers are always hard code the user in web.config - use a login window and pass those fields to the IReportServercredentials or create one user for everyone.
When the person who asks the question comes back and says that doesn't work there is not answer.Does anyone know how to do this? I have VS 2008 ( and 2010 ) I am sending the info to SSRS 2005 server.As anyone using SSRS knows that if the reports have parameters and udf behind the report to inspect who the user is, then you have to pass that user to the report.
[Code]...
I have been programming steady with vb.net for a year now and was all happy about using the List view and email etc from web sites. I even used a reportviewer to pdf to email attach, cool. Now I feel quite lost and realize I have not been using properties, etc. That is my background.

I'm trying to setup a WCF web service to be consumed by JavaScript using JSON and jQuery.I've noticed that you can send JSON without a DataContract if the service method parameters match the naming structure of the JSON object:
<ServiceContract(Namespace:="http://foo.com/bar")>
<AspNetCompatibilityRequirements(RequirementsMode:=AspNetCompatibilityRequirementsMode.Allowed)>

I am making use of a 3rd party dll and am encountering some strange behavior in VB, which doesn't occur in C# Perhaps someone can explain what is going on. Anyhow, I am making use of a method in this 3rd party library which accepts an array parameter ByRef. The end result is the variable should remain null after the method call, but it is returning initialized for some reason.

I want to build an application, which can remote access to SQL Server in Server Machine.I used to build one, and it also can access to SQL Server in other pc. But when i promote it to become a Server(to become a Domain Controller). My application has never access to SQL Server. I don't know what to do now?
remember: I want to build an application, which is accessing to SQL Server in Window Server(Client/Server Application).

I occasionally find myself passing this or Me to a child object. Such as this condensed real-world example...
Public Class Entity
Private mValidator as New EntityValidator()
Readonly Property IsValid()[code]....
I'm concerned about .Validate(Me).I get no warnings or Code Analysis violations, but it just feels wrong. I get nervous about infinite recursion and garbage collection.

I am creating a procedure and would like to know if I can pass the name of a property. I.e ComboBox1 so I can change the properties of that object. What I have done is create a procedure to populate a Combobox from my MySQL database. What I want to do now is populate the relevant Comboboxes without having to create a new procedure specifically for each combobox. I can create a procedure for each Combobox but the whole reason for procedures and functions are to minimize repetitive code and to make code easier to manage.
At the moment my procedure is ProcedureName(ComboBox1, "DatabaseName", "DatabaseField").
What I want to be able to do is do
ProcedureName(ComboBox1, "DatabaseName", "DatabaseField1").
ProcedureName(ComboBox2, "DatabaseName", "DatabaseField2").
ProcedureName(ComboBox3, "DatabaseName", "DatabaseField3").

I've found a few examples of using vb.net to access an sql database, so far none of them have worked . They all involve using DataReaders. Maybe its the fact that the sql db is not on the same machine as the application.I was just wondering if anyone had a more comprehensive example of using VB.NET to access a remote sql server.
EDIT:I've received a few helpful comments an replies already. So far my connection string looks like:
"server=sqlblah.myhost.com;uid=myuser;pwd=pass;database=testdb"
Probably also good to mention their is no editing of the tables a this point, just reading.

How can I connect to a database using sql server 2000 and stored in another PC with vb net (still in 1 LAN)?So that PC only stores the database, and another PC store the user interface and business logic.Is it related to the connection strings, on the datasource, we just put the IP address for that remote sql server?

I want to understand the concept of connecting to a remote PC or server. I'm working on an app that will connect to a remote server. Read a value from a registry key and then display the results in a text box. It will also connect and search for a specific log file on a server. I understand how to read the files. I'm just not sure how to connect to a machine remotely if I have valid credentials. There seems to be sever ways to accomplish this. I want the most efficient way using vb2008.

I'm been learning about connection strina I have been able to succesfully connect to a sql database stored locally on my Pc.The next logical step would be to connect to a database stored on a remote server. My question is does anyone of a sql database ( or any other type of database ) which can be openly accessed by the general public. Does anyone know if a web hosting service would allow me to remotely connect to a sql database ? Could I for instance upload my database onto a web hosting service and try connect to a remote database that way

how to send a log using vb.net console app to a external server? I have the application sitting in a store oulet, then I need this application to send over a log file.
I have a couple of ideas.. one is using a tcp listener and sender, then the listener logs it over in the server.
Another is using a ftp send.
but I would prefer it to be coded in the program itself.

I need to write a procedure which will allow me to set readonly attributes for certain objects, for example:My form contains two text boxes box1, box2.My sub procecdure will contain code which sets box1.readonly() = true, but i dont want to name the "box1" in the sub procedure but pass it as a parameter....I thought this could be achieved using :
private sub disableobject(byval inobject as system.object)
inobject.readonly() = true

Scenario: I want to develop an application.The application should be able to connect to my remote server and download data to the local disk , while downloading it should check for new files and only download the new ones simultaneously creating the required(new) folders. What am i doing?: The app first checks for internet connection , if available pings the server to check if the server is active.Then it has to download the new files.
Problem: I have no idea how to compare the files in the server with the ones in the local disk.How to download only the new files from the server to the local disk? What am thinking?: If i can create the exact folder structure(hierarchy) in the local disk as it is in the server...than i can download the new files accordingly to folders by maintaining some index file in both server and local disk.
