How do I resolve active directory connection errors when using dcpromo?

- by Middletone

When attempting to promote a secondary server to an existing active directory forest I receive the following error message and can no longer continue. Failed to examine the active directory forest. Value ridMasterDSA.partentDN not found What can cause this and what can be done to fix it? Both servers are 2008 running on x64 and can see each other on the network via their names. FYI: The firewall is turned off on both machines so there should be no issue there. Also the server that i'm adding is already a part of the domain. One server is already a domain controller but I want to add a second to it.

How do I extract all the files in a VHD to a hard disk including permissions?

- by Middletone

I'd like to know wha thte best way is to make an exact copy of a vhd image and pu tit onto my hard disk. I've tried xcopy but there seems to be a number of issues rlated to permissions when doing this. Ideally I'd like to copy the bits so that they match exactly on the new drive. I encountered this when trying to restore a vista backup only to discover the idiots work who decided to not let me restore a 400 gig image to a 1 TB drive size. I've sucessfully mounted the drive in Win 7 which is the environment in which I'm trying ot copy these files.

How can I make the modal popup scroll its contents with the page?

- by Middletone

I've got a modal popup and when it loads contents that are taller than the browser height I am unable to scroll down to view the rest of the information. Instead the background can scroll but the popup won't. Instead I'd like to have the popup stay put and when the user scrolls up or down it leave the popup in place and let them scroll to the bottom of the contents. If you make a super long post on Facebook the popup works correctly and I'd like to know how I can get this same effect with this control.

How can I track an asp.net pages size without tracing?

- by Middletone

I want to be able to track the amount of data that is being transfered from my web site to each user that accesses the site. I can do this for file downloads and such but what about the pure html content itself. How can I track the output size of a page (or the data that's trasnfered via an AJAX call) to the client and log it against a particular users session? Also how would this differ when GZip is used in IIS 6.0?

How do I resize an iframe with dynamic content?

- by Middletone

I'm populating an iframe with some contents that are injected into it but I'm unable to size it correctly. I've tried a variety of methods but here is the most recent code. After populating the iframe with an html based mail message it doesn't seem to register the scroll height. <iframe scrolling="no" width="100%" onload="javascript:(LoadIFrame(this));" > HTML content goes here. Make sure it's long enough to need to scroll before testing. </iframe> <script type="text/javascript"> function LoadIFrame(iframe) { $("iframe").each(function() { $(this).load(function() { var doc = this.document; if (this.contentDocument) { doc = this.contentDocument; } else if (this.contentWindow) { doc = this.contentWindow.document; } else if (this.document) { doc = this.document; } this.height = (doc.body.scrollHeight + 50) + 'px'; this.onload = ''; }); txt = $(this).text(); var doc = this.document; if (this.contentDocument) { doc = this.contentDocument; } else if (this.contentWindow) { doc = this.contentWindow.document; } else if (this.document) { doc = this.document; } doc.open(); doc.writeln(txt); doc.close(); }); } </script>

Gridview looses ItemTemplate after columns are removed

- by Middletone

I'm trying to bind a datatable to a gridview where I've removed some of the autogenerated columns in the code behind. I've got two template columns and it seems that when I alter the gridview in code behind and remove the non-templated columns that the templates loose the controls that are in them. Using the following as a sample, "Header A" will continue to be visible but "Header B" will dissapear after removing any columsn that are located at index 2 and above. I'm creating columns in my codebehind for the grid as a part of a reporting tool. If I don't remove the columns then there doesn't seem to be an issue. <asp:GridView ID="DataGrid1" runat="server" AutoGenerateColumns="false" AllowPaging="True" PageSize="10" GridLines="Horizontal"> <Columns> <asp:TemplateField HeaderText="Header A" > <ItemTemplate > Text A </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Header B </HeaderTemplate> <ItemTemplate> Text B </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> For i = 2 To DataGrid1.Columns.Count - 1 DataGrid1.Columns.RemoveAt(2) Next EDIT So from what I've read this seems to be a problem that occurs when the grid is altered. Does anyone know of a good workaround to re-initialize the template columns or set them up again so that when the non-template columns are removed that hte templates don't get removed as well?
