  • Linkbutton to open Windows Explorer from Gridview

    - by xt_20
    Hi all, I have a link in a Gridview that I want opened in Windows Explorer (or explorer.exe). <asp:GridView ID="GridView1"runat="server" > <Columns> <asp:TemplateField> <ItemTemplate> <asp:LinkButton ID="DeploymentLocation" runat="server" CommandName="OpenLink" Text='<%# Eval("DeploymentLocation") %>' CommandArgument='<%# Eval("DeploymentLocation") %>' /> </ItemTemplate> </asp:TemplateField> </Columns> and in codebehind I have this: protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e) { Process.Start("explorer.exe", "/n," + e.CommandArgument.ToString()); } Obviously this doesn't work as Process.Start only works if I have full permissions, etc, etc. I heard that I can use Javascript to do this, but haven't succeeded so far. Basically, what I want is the exact link that is displayed in the grid to be opened when clicked. Any help would be much appreciated! Thanks!

  • How to seralize only some properties in .Net?

    - by Beta033
    This is for a web project so i have several classes that inherit from Web.UI. I only want to serialize very particular properties (basically, only local properties) I'm aware of the XMLIgnore property that can be placed on a property to ignore items, but this won't work in my context since that would require modifying a bunch of stuff that i really don't want to modify (and probably can't). So how do i tell the xml serializer to ignore everything except for X and Y or tell it to seralize just X and Y? i could just create my own xml in a string builder or something and if that's the only way, so be it. however i'm looking for a method that will employ the built in XML stuff. Thanks

  • Deploying a .Net App Source Control (SVN) over 32-bit AND 64-bit dev stations

    - by Mika Jacobi
    Here is the situation : Our Dev Team has heterogeneous OS systems, scattered between 32-bit and 64-bit. This is not ideal, we are actually planning to homogenize our infrastructure, but in the meantime we have to deal with it. The issue is that when a 32-bit developer checks out a 64-bit solution on SVN, he has to manually change the target platforms all over again to get it compiled (not to mention other side problems) My question is : What clean (though temporary) solution could be addressed in such situation, permitting each developer to keep his default project/platform settings while checking out and in from SVN. I guess that -at least for the first time a project/solution is checked out, a dev still has to tweak the setting manually to compile it properly. After that, according to relevant SVN filters, it is possible to ignore some settings files (which ones, by the way?) I am open to all clever and detailed suggestions. Thanks.

  • I need a tutorial for IIS/ASP.Net administration

    - by TheCodeMonk
    My technical support staff is only a little familiar with IIS and that's only as far as install goes. They need to install/update and configure ASP.Net web applications and WCF services that we write. Does anyone know any good tutorials/books/web sites that can help them understand some of the basic concepts of web applications and maintaining them on IIS?

  • VB.NET Window Screen Capture (ALT+PRINTSCREEN)

    - by Steve Thomas
    Hi, I found that code somewhere and I find it quite useful but I would like to find a way to make it work so it capture only the given window target. Maybe with a processID or Window Name. Even if that window is not active. I do not want to make that window active but want to get a screen capture like if I was doing Alt+PrintScreen on it. Here is the code that works for full Screen Capture Private bmpScreenShot As Bitmap Private gfxScreenshot As Graphics bmpScreenShot = New Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, PixelFormat.Format32bppArgb) gfxScreenshot = Graphics.FromImage(bmpScreenShot) gfxScreenshot.CopyFromScreen(Screen.PrimaryScreen.Bounds.X, Screen.PrimaryScreen.Bounds.Y, 0, 0, Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy) bmpScreenShot.Save(fileName, ImageFormat.Png) I use the Visual Basic 2008 Express Thank you in advance!

  • .Net 3.5 Windows Service hide WCF Service Host

    - by Melursus
    I got a Windows service installed on my development machine (that I made) and I want to interact with it. For a reason I don't know, each time I start the client, a WCF Service Host pop and said that the address is already in use ... which is true ... but how can I do to NOT start that Windows ? Is it because my two projects (server and client) are in the same solution ?

  • Create Access databases programatically through vb.net

    - by user87225
    Let me preface this by saying that I know this is a stupid way to go about this, but it needs to be handled in this way. I need to make an application that from a master database creates a number of access database files (tables of a larger db), then these are manually given to users who fill in data, the database files are emailed back to a user who, through the application, combines them again. The only part of this that I am unsure about is problematically creating the access db's. I have read that through Microsoft Jet OLE DB Provider and Microsoft ADO Ext I can create them (the tables and data), but I also need forms. I have yet to start writing anything and this is away from my area of work, so any insight/links would be much appreciated. Also, I would hope to be able to write this in the free express version of visual studio. Are there components needed that would prevent me from this? Thanks.

  • .NET 2.0: Invoking Methods Using Reflection And Generics Causes Exception

    - by David Derringer
    Hi all, I'm new to Stack Overflow, so forgive me. I've just started transititoning over to C# and I am stuck on a problem. I am wanting to pass a generic class in and call a method from that class. So, my code looks as such: public void UpdateRecords<T>(T sender) where T : new() //where T: new() came from Resharper { Type foo = Type.GetType(sender.GetType().ToString()); object[] userParameters = new object[2]; userParameters[0] = x; userParameters[1] = y; sender = new T(); //This was to see if I could solve my exception problem MethodInfo populateRecord = foo.GetMethod("MethodInOtherClass"); populateMethod.Invoke(sender, userParameters); } Exception thrown: "Object reference not set to an instance of an object." Again, I really apologize, as I am nearly brand new to C# and this is the first time I've ever handled reflection and generics. Thank you!

  • How do you pass a generic delegate argument to a method in .NET 2.0

    - by Seth Spearman
    Hello, I have a class with a delegate declaration as follows... Public Class MyClass Public Delegate Function Getter(Of TResult)() As TResult 'the following code works. Public Shared Sub MyMethod(ByVal g As Getter(Of Boolean)) 'do stuff End Sub End Class However, I do not want to explicitly type the Getter delegate in the Method call. Why can I not declare the parameter as follows... ... (ByVal g As Getter(Of TResult)) Is there a way to do it? My end goal was to be able to set a delegate for property setters and getters in the called class. But my reading indicates you can't do that. So I put setter and getter methods in that class and then I want the calling class to set the delegate argument and then invoke. Is there a best practice for doing this. I realize in the above example that I can set set the delegate variable from the calling class...but I am trying to create a singleton with tight encapsulation. For the record, I can't use any of the new delegate types declared in .net35. Answers in C# are welcome. Any thoughts? Seth

  • ASP.Net event only being raised every other time?

    - by eftpotrm
    I have an ASP.Net web user control which represents a single entry in a list. To allow users to reorder the items, each item has buttons to move the item up or down the list. Clicking on one of these raises an event to the parent page, which then shuffles the items in the placeholder control. Code fragments from the list entry: Public Event UpClicked As System.EventHandler Protected Sub btnUp_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUp.Click RaiseEvent UpClicked(Me, New EventArgs()) End Sub And the parent container: rem (within the code to add an individual item to the placeholder) AddHandler l_oItem.UpClicked, AddressOf UpClicked Protected Sub UpClicked(ByVal sender As Object, ByVal e As EventArgs) MoveItem(DirectCast(sender, ScriptListItem), -1) End Sub It originally looked in testing like every other time the value for sender (verified by its properties) that reaches UpClicked is of an adjacent ListItem, not the one I've just clicked on - the first click is always wrong, then the second for the correct control. At present, testing appears to show that the button's click event is just being ignored every other time through. Breakpoints on the click events within the control simply aren't being hit, though the events are definitely being established. Why?

  • Mdi Children Changed in .Net

    - by Ben
    Hi Is there a simple way of tracking the change of an Mdi's children i.e. when they are created and closed, something like an event OnMdiChildListChanged (I realise this doesn't actually exist). I am also aware that I could have a method within my Mdi that handles the creation of child forms and logs the state of them or even create an Interface that defines that a child form has a "NotifyParent" method that is then called on close of the form, but i was wondering if there was any built in events that i could plumb into? Thanks

  • Setting Focus with ASP.NET AJAX Control Toolkit

    - by Jonathan S.
    I'm using the AutoComplete control from the ASP.NET AJAX Control Toolkit and I'm experiencing an issue where the AutoComplete does not populate when I set the focus to the assigned textbox. I've tried setting the focus in the Page_Load, Page_PreRender, and Page_Init events and the focus is set properly but the AutoComplete does not work. If I don't set the focus, everything works fine but I'd like to set it so the users don't have that extra click. Is there a special place I need to set the focus or something else I need to do to make this work? Thanks.

  • Facebook Card Game? Which architecture?

    - by Ben
    I am developing a Facebook Card Game for my thesis and i am wondering which architecture fits best? I am going to develop the game using Silverlight + ASP.NET. On the one side the game should contain player vs. player card games. On the other there will be also a lot of contant similar to Mafia Wars(or any other game like that) where you just interact with the server (incl. database) I read a lot about ASP.NET MVC, Silverlight MVVM and that stuff. But what fits best for a game like that? Also i am not sure if i should go with Silverlight 4 already? I don't want to start the wrong way. I really appreciate your help.

  • .NET platform independant sync framework

    - by Quandary
    Question: I need to synchronize a few ActionScript files from my computer to a network share (backup). I saw a quick fix would be using Microsoft Sync Framework for this, and write a windows service. My problem is I also use Linux, and before I start with MS vendor lockin, is there any sync framework/library/whatever I could use that works accross platform? Or does the MS sync framework work on Linux, too? It is my understanding that it is a wrapper around some com objects, thus it wouldn't work. All I need is synchronizing files. So never mind the database part, although it would be nice to have it, too.

  • The cost of finalize in .Net

    - by Jules
    (1) I've read a lot of questions about IDisposable where the answers recommend not using Finalize unless you really need to because of the process time involved. What I haven't seen is how much this cost is and how often it's paid. Every millisecond? second? hour, day etc. (2) Also, it seems to me that Finalize is handy when its not always known if an object can be disposed. For instance, the framework font class. A control can't dispose of it because it doesn't know if the font is shared. The font is usually created at design time so the user won't know to dispose it, therefore finalize kicks in to finally get rid of it when there are no references left. Is that a correct impression?

  • Appended content using jQuery 'append' is not submitted?

    - by YourMomzThaBomb
    I'm new to jQuery so this may be a real simple answer. I have a ASP.NET project that I'm trying to dynamically add content to a span element by typing into a text box and clicking a button. Sounds simple right? Well, I can get the content to added, but when the form is submitted the span element is still empty? Why is the new data not submitted? What step am I missing? Please help. Here's some sample code: < span id="tagContainer" runat="server"< /span < input type="text" name="tag" id="tag" / < input type="button" name="AddTag" value="Add" class="button" onclick="addTag();" / function addTag() {    if ($("#tag").val() != "") {       $("#tagContainer").append('$("#tag").val()');       $("#tag").val("");    } }

  • How to bind a label inside a gridview to another table?

    - by Kolten
    I have a very standard Gridview, with Edit and Delete buttons auto-generated. It is bound to a tableadapter which is linked to my "RelationshipTypes" table. dbo.RelationshipTypes: ID, Name, OriginConfigTypeID, DestinationConfigTypeID I wish to use a label that will pull the name from the ConfigTypes table, using the "OriginConfigTypeID" and "DestinationTypeID" as the link. dbo.ConfigTypes: ID, Name My problem is, I can't automatically generate Edit and Delete buttons using an Inner Join in my dataset. Or can I? FOllowing is my code: <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" AutoGenerateDeleteButton="True" AutoGenerateEditButton="True" CssClass="TableList" DataKeyNames="ID" DataSourceID="dsRelationShipTypes1"> <Columns> <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True" SortExpression="ID" Visible=False/> <asp:TemplateField HeaderText="Origin" SortExpression="OriginCIType_ID"> <EditItemTemplate> &nbsp;<asp:DropDownList Enabled=true ID="DropDownList2" runat="server" DataSourceID="dsCIType1" DataTextField="Name" DataValueField="ID" SelectedValue='<%# Bind("OriginCIType_ID") %>'> </asp:DropDownList> </EditItemTemplate> <ItemTemplate> &nbsp; <asp:Label ID="Label2" runat="server" Text='<%# Bind("OriginCIType_ID") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Name" SortExpression="Name"> <EditItemTemplate> <asp:TextBox ID="TextBox3" runat="server" Text='<%# Bind("Name") %>'></asp:TextBox> </EditItemTemplate> <ItemTemplate> <asp:Label ID="Label3" runat="server" Text='<%# Bind("Name") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Destination" SortExpression="DestinationCIType_ID"> <EditItemTemplate> <asp:DropDownList ID="DropDownList3" runat="server" DataSourceID="dsCIType1" DataTextField="Name" DataValueField="ID" SelectedValue='<%# Bind("DestinationCIType_ID") %>'> </asp:DropDownList> </EditItemTemplate> <ItemTemplate> <asp:Label ID="Label1" runat="server" Text='<%# Bind("DestinationCIType_ID") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> So I did try to create my own edit and delete buttons, but kept receiving the error "cannot find update method" or something similar. Do I have to manually code the delete and update methods in my code-behind?

  • What's the most simple way to retrieve all data from a table and save it back in .NET 3.5?

    - by zoman
    I have a number of tables containing some basic (business related) mapping data. What's the most simple way to load the data from those tables, then save the modified values back. (all data should be replaced in the tables) An ORM is out of question as I would like to avoid creating domain objects for each table. The actual editing of the data is not an issue. (it is exported into Excel where the data is edited, then the file is uploaded with the modified data) The technology is .NET 3.5 (ASP.NET MVC) and SQL Server 2005. Thanks.
