IDE :: Setting The Same Properties For All Forms In A Single Application
May 15, 2012
Most of the apps I write have a base / home form and a few other forms (three of four typically) which pop up in response to controls clicked by the user. I'd like to be able to set some properties to be the same for all the forms in an app; particularly properties like BackColor and FormBorderStyle. Yes, I can manually set the individual properties for each form in the VB IDE, but I'd prefer to be able to have one line of code in the base / home form for each property along with one line for each dependent form which says something to the effect of "use the same property value as the base / home form has". Overall, my objective would be to have one single line of code in the app which, when changed, would apply the changed property to all the forms. For example, a single line which I can change to take the BackColor from Apple to Orange for all the forms ...
Did vs2008 or vb.net got some of the solution to solve properties setting of the components are same with each other? Example: like I want to standard the datagridviews' property, each of the datagridviews' property is same with each other. but each time I create the new datagridview. I have to manually set the datagridview 1 by 1.
I need to work with custom controls, I want to be able to set the properties of my controls so when I put them on my windows forms they will show up in the properties window thing.
I have a icon for my application that I set in the project properties window there is a little drop down box to browse to the icon location. While debugging everything is good. Once I build the app and place it on a PC and manually start the app all is good. My app starts with windows and now every time the program goes to start I get an error that the icon cannot be found in the DocumentandSettingUSERNAME folder. So the question is do I have to place my app icon in this folder? In design I have the icon in the binDebug folder and that is were I point to in the Project properties page. I am using VS 2008 VB.net.
I wish to turn on the Single Instance Application choice in Visual Studio 2008 properties. To do so, I must choose "Enable Application Framework". When I do that, my ONLY choice is to choose a Startup Form, not a Startup object. This makes no sense to me. I have a tray application, and I check to see which form I should load, a logon form, or the main form. But since I am forced to choose a startup form, I MUST load the logon or main form to begin with. But I don't want to. I want startup code to determine which one to load first. So then I am playing with making the OTHER form invisible, even if the startup form, but that is a mess.
If you mark your application using "Make Single Instance Application" option in the application settings tab and run your application under a GUEST account or a restricted limited/standard account the application throws UnAuthorizedAccessException or CantStartSingleInstanceException.
Take the following steps to reproduce this behavior.
1) Create Windows Form application.
2) Enable the "Make Single Instance Application" in the project properties.
3) Log onto a GUEST account and open the application twice to simulate StartUpNextInstance.
We need developers to reproduce this behavior and post any valuable input if you experience these symptoms.
When posting information please include the following:
a) The operating system version + service pack.
b) The .NET framework version used.
c) Verify this symptom is present when running under GUEST account.
To workaround this issue turn off the "Make Single Instance Application" option ad create a Local named mutex in the StartUp() event.
I'm setting up a simple app that has 2 variables, one from a combobox and one from a textbox.Putting all my code directly in the button1_click sub works just fine, however, I wanted to add a marquee progress bar so I tried to implement a backgroundworker.
[code]...
and call it with Me.Invoke(New SetComboBoxTextDelegate(AddressOf SetComboBoxText), ComboBox1.Text)but it still throws the Cross-thread operation invalid error.
I have a byte array with 512 Elements and need to get and set a single bit of a byte in this array.The operation must not change any other bits, only the specified one.So if I have a byte like &B00110011 and would like to change the third bit to 1 it should be &B00110111.
Like this:Dim myarray(511) as byte myarray(3).2 = 1 ---> This would change the third bit (start counting at 0) of the third byte to 1 I know it should be easily possible using bit-masking but I don't have the time to try for days to get it working.
I've played around with this and have figured most of it on how to set the properties of most controls in the designer. I have 2 check boxes I need to set the values on but do not know how. 2 fields one for each in the db with a char(1) value, can be Y or N. If it a Y in the db how would I set it as checked on the form? 'cboPosition Me.cboPosition.DataBindings.Add(New System.Windows.Forms.Binding("SelectedValue", Me.FmfieldmanmasterBindingSource1, "position_name", True)) Me.cboPosition.DataBindings.Add(New System.Windows.Forms.Binding("Text", Me.FmfieldmanmasterBindingSource1, "position_name", True)) [Code] .....
I'm stuck trying to figure this one out. I am trying to set a GridViews Column properties by using reflection and the Extended properties off a DataTable.the Code looks something like this
Dim colproperty As PropertyInfo = gv.Columns(col.Ordinal).GetType.GetProperty(key) Where key = "ItemStyle"
So I get the ItemStyle Property by I'm unsure how to set the next varibel which would be BackColor:Red in the collection i have that key access. This is all text.in the XML the extendedproperty is set like this
msprop:ItemStyle="BackColor:Red"
I can easily set all of the attribues for a gridview using something simular to this but of course gridview columns do not have attributes only properties.
Gridview attribute setting code Dim nvCollection As PropertyCollection = table.ExtendedProperties For Each key As String In nvCollection.Keys() Dim colproperty As PropertyInfo = labelOut.GetType().GetProperty(key)
is there any trick (because I can't think of anything else ! ) to massively set all of the properties , of a user defined class , to their null values ? You see , I have a class called Apartment and it has a lot of properties (it only has properties , no methods or events , if that's important) and those properties are either strings , doubles or integers . I want each time I create a new instance of that class (a new apartment , that is) to automatically set those properties to their null values . That is all of the strings to be equal to "" and all of the numbers to be equal to 0 . Back in VB6 I could rely on VB6 to do this automatically , but now in VB .NET , whenever I create a new instance of a class , all the properties start with the value = Nothing . I know I can define every property in the class module like that : Public MyVariable As String = "" but I'd like to keep them as they are and set their null values directly whenever a new object of that class is created .
In VB6 I would simply retrieve the user font setting from the .ini file, load into variables and then apply to the appropriate control.
text1.fontbold = userfontbold text1.fontitalic = userfontitalic text1.fontunderline = userfontunderline etc.
I'm struggling to understand how to do this vb.net The following code works, but sets all three at one time
Text1.Font = New Font("Courier", 10, FontStyle.Bold Or FontStyle.Italic Or FontStyle.Underline)Since the user can have many different combinations of settings, I would like to be able to add just one of these properties at a time, but can't seem to figure out how to do it.
i am writing a VB front end (VS 2008 .NET 3.5) to a data loading program that involves moving the contents of CSV flat files into SQL Server 2005 staging tables. I have had some experience with DTS in SQL 2000 so I decided to use SSIS packages to load the CSV data. Creating the packages in BIDS worked fine for the development environment where I hard-coded the Connections and file paths. The problem arises when I will release this program to 30 different sites that do not have SQL Server admins to help changing the configuration.
I have a SQL table in which I will put all the necessary path information and I can pull that into the VB program on startup. I need to see an example of how I can set the properties from VB once the package is instantiated and opened.Here is an example of where I plan to set those properties and run the packages.
Private Function RunPackages() As Boolean Try Dim oApp As New Application Dim oPackage As New Package
[code]....
Even though I am using a configuration file in the example, I am finding it difficult to edit the configuration files for each site. I see that there are methods and properties exposed for the oPackage instance. However, I can't find a good reference for the Class model to use as a guideline. All the examples expect packages to be run and configured with SQL Server and BIDS. direct manipulation of package properties in VB or C#?I am now considering using the old standby SQL Bulk Insert. It almost appears as if the Data Tasks are just wrappers for the Bulk Insert operation. Furthermore we have several sites still using SQL Server 2000. With the economy the way it is, most of those sites do not want to spend ANY extra money upgrading to SQL 2005 or 2008.
However, having a good resource to learn how to manipulate SSIS packages from the CLR would be very helpful. I have heard that in SQL 2008 things have changed even more. It is maddeneing that once I learn a "new" Microsoft technology it seems to be discarded by MS in their next release in favor of a "better" alternative.
I have a DetailsView which has two fields - one that is visible, one that is not. The first the user fills out, the second I want to auto-populate. Unfortunately, I haven't been able to find a way to set the value in this second invisible field. I've tried adding code like this to the Page_Load:
If Not IsPostBack Then DetailsView1.DefaultMode = DetailsViewMode.Insert Dim txt1 As TextBox = DirectCast(DetailsView1.FindControl("Type"), TextBox) txt1.Text = "administrator" End If
But this returns an error of "Object reference not set to an instance of an object." Any ideas on how to accomplish this - either using the method above or another method?The hoped for end result is that when a new record is inserted via the DetailsView that this record will include the username (entered by the user) as well as the "type" of "administrator"
I have built a deployment program (vS 2008 Standard Edition) and tried to set the Properties column to a product name and company. I have also tried leaving these blank. I'm really trying to configure my setup.exe so that it installs by default in Program FilesMyFolderName without adding a subdirectory to the path. Is there somewhere I can specify exactly the default path for my setup without it adding a subdirectory? What do I edit?
Passing data between forms without any public methods or properties on the forms. everything but the "Controller" class, which I would like you furnish. I just changed the title from "Intermediate" to "Beginner" This solution is an example of the Observer Pattern. The "Controller" class is the "observed" class, which in this case means it publishes events.
' File Definitions.vb
Public Delegate Sub MessageDelegate(ByVal sender As Object, ByVal e As MessageEventArgs)
Public Class MessageEventArgs : Inherits EventArgs Public Message As String
[CODE]...
The program should initially display Form1, and Form2. Clicking of the button on either form will modify the Title Text of both forms. I think that you will find the final end result to be pretty neat, as it works with any number of open forms not just two. I think asking for the Controller class is easier than asking for the code in the forms. My solution for Controller class has 7 lines of content, 9 lines if you include Class, EndClass. A minimal solution could achieved with only 4 lines of content, but it would a textbook example of bad programming.
I'm making an editor for my app. which allows the user to change properties of the controls including the font.I'm storing the values in a collection but I'm having trouble re-setting the fontstyle from the stored value. I'm storing the font information like so...
I am not able to find the Exclude Command in VB 2010 Express. I have no idea which version of Visual Studio it is working with. I've got one 217MB VB 2010 Express file and many 2008 VB Express files with one of them measuring 31 MB. There many other SQL files and .Net Files.
I'm writing vb.net code with MS Visual Studio 2005.When running my application I get "foo.exe is already running on this machine".(Even though I'm running faa.exe instead
My program has two forms which get data from the same data source. After binding controls to tables and fields on both forms, I noticed each form has it's own apparently duplicate DataSet. Is it standard practice for each form to have its own DataSet even though they use the same ConnectionString and connect to the same database at the same time?
I've got to the stage where I want to make changes to my application so that all of my forms appear to the user as a single window.
I have a main Form with a menu bar which opens up three separate forms. Only one forms is visible at any time.
One way to do this, that I can think of, is to place all the controls from each of the "auxiliary" forms on a panel contained in the main form and then show and hide the panels, when needed. I can envisage this being a big headache though.
Another way would be to give each form a menu bar and make it look like the main form so that the user would not know the difference (with a bit of luck).
I just wonder if there are better ways to do this. Maybe if I could incorporate one form into another form?
i wants to load many pages in same form which each of the pages contains different messages.example....if i press more in the page no1(form 1) it should load the page no2 at the same form(form 1)...
I've written an application with about 30 forms and am almost ready to publish, my biggest concern though is that i'm not sure if its a normal thing to do having all these forms and hiding, disposing and showing forms throughout the use of the application.I've toyed with the idea of converting to a MDI Child / Parent interface as well as having one form with lots of subcontainers that are hidden and then hiding / showing them as the navigational buttons are shown.Ive worked on this application for about 8 months now, but would be happy to rewrite the interface and appearance of it if i know that it is not generally an acceptable practice having forms flashing open and closed while navigating through the application.
