• Windows Forms VB2005 Add system Date to new record in Datagridview new

  Hello, When I push the add button a new row is added to my datagridview. How can I automatically insert the system date in the new row in the column 'Date' I hope to hear from you guys... It's not exactly code... go to your DataTable design, highlight the field you want to put the date in, and enter "=Now()" in its DefaultValue property. EDIT - This won't work.  I think the reply refers to the column setting of the DataGridView. ...Show All

• SQL Server DataGridView/SQL Express - Updating record using seperate form

  Hi, I am currently using VC++/Cli 2005. In a project, I'm using a DataGridView control to show records from a SQL Express 2005 table. Instead of updating a specific item directly within DataGridView control, I would like to open a new form and allow user to update selected record/item within that form. The reason to update this way is conditionned by the fact that I have 3 levels of detail as following: Level 0 Level 1 Level 2 1:N 1:N Furniture --> Component --> Component You all understand that update form of Level1 will/must include, as Level0 do, another DataGridView control to display/detail all related items issued from next level. This explains why I can't ...Show All

• Smart Device Development GPSID: GPSOpenDevice does not start GPS

  I'm desperately trying to access the built-in GPS of a FujitsuSiemens PocketLoox N560. I can successfully call GPSOpenDevice(NULL, NULL, NULL, 0); and also get a correct handle. But the GPS hardware does not start. The PocketLoox normally indicates active GPS with a blinking orange light, but thats not the case. So far I tried the following things: Accessing the GPS the 'old fashioned' way, using a COM-Port connection. That works. As soon as I open the COM port, blinking light goes on & the GPS (sporadically) sends NMEA messages. Run the C# sample from MSDN - that also works. (But I need a C++ solution for my project What else do I have to do to start the GPS hardware ! Here's the source code I'm using: [...] if (gps_handle == NULL ...Show All

• Gadgets How to Save User Preferences on Spaces?

  Can someone explain to me how to save user preferences on Spaces or point me to some instructions If there is a way to determine whether a gadget is on Spaces or Live, that would be good to know too so that I can hide the preference link in Spaces view mode. I got one of my gadgets to save user preferences on Live but it's not working on Spaces. Thanks Someone with more knowledge will be around soon I am sure, but this is the method I use var prefValue = m_module.getPreference("some value"); if (prefValue == null) { m_module.setPreference("some value", " some value "); } I just asked a similar question about view mode vs author mod ...Show All

• .NET Development Problem about opening Office document in a new Window.

  Hi all (first post yipee), anyway.... currently my web application have an icon that allows the user to edit an office document (word./excel), it is begin brought up by window.open(). However, problem lays here, since this isn't a model/modeless dialog, the user is allowed to go back to the application and reclick the edit icon. This causes the first office document that popped up to become blank and a second office document window will come out. The function of the icon is simple, it just calls window.open(), i am just wondering if there is a way to not allow the user to go back to the parent window and click on the edit icon again. showmodelessdialog() does not work in this case, i have tired opening an excel document with it but it re ...Show All

• Architecture Problema con la arquitectura de una aplicacion (referencias ciclicas)

  Hola, tengo un problema con la arquitectura de capas. Necesito que dos capas se comuniquen de forma reciproca la una con la otra y no se como hacerlo para no hacer referencias ciclicas. Espero que me podais ayudar, gracias. Shiveta, Una manera de aproximar este problema, si no puede ser evitado, es definir un conjunto externo de interfaces que definan las responsabilidades y funciones de cada capa en forma externa a la misma (normalmente en un assembly independiente), de forma tal que introducirlas como un tercer elemento rompan la referencia ciclica. De esta forma, cada una de las dos capas implementara las interfaces que le corresponden, a la vez que usara las interfaces opuestas para interactuar con la otra capa. Para terminar de ...Show All

• Visual Studio project templates disappeared

  From one day to another my project templates disappeared. I can only create a Webapplication, but no WindowsApplication. I can't add a WindowForm to a project, only inherited forms. What can I do I reinstalled Visual Studio and followed the instructions of the Thread "Visual Basic Templates disappeared" but it didn't help.

• Visual C++ Getting garbage setting dialog box text

  Hi Folks; I'm trying to set the text of a dialog box with SetDlgItemText. As an example I'm trying: SetDlgItemText(hwnd, IDC_F1, "Some text"); where IDC_F1 is defined as the ID for an edit box. What I'm getting is just garbage and I thought maybe it was my font but I've set it do Courier New, size 8 which I thought was pretty standard. Maybe someone could shed some light on my sitation. I'm still having a couple issues getting this to work :(. Essentially what I have is a struct: struct WMIData { char CompName[25]; }; and the idea is this will be used in the gathering of system data. It gathers just fine but I still need to convert it to a format that I can use in a text box. L"Some tex ...Show All

• Visual Studio 2008 (Pre-release) LineBreaks or Environment.NewLine -- which is more efficient?

  Quick question: in flow documents, are <LineBreak>s or inlines appended with \r\n more efficient memory/perf wise Thinking simply, I'd guess that the 4 extra bytes within the space allocated for the inline text is a lot cheaper than the extra 8 bytes on the GC heap + 4 bytes for pointer that it costs for a <LineBreak>. But if in rendering it has to do something fancy like convert \r\n to a LineBreak object, <LineBreak> would be cheaper. Thanks in advance, Rei There is already an overhead associated with using WPF document formatting. Unless you have hundreds of thousands of hard line breaks in your document, the savings of using NewLine (if any) wouldn't be significant ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Question about content pipeline

  If i do this model1 = content.Load< Model >( "myModel" );   model2 = content.Load< Model >( "myModel" ); do model1 and model2 hold the same reference if not, does the data inside them (the vertices and index buffers) hold the same reference Thank You Yes, they are the same reference ... the content manager notes that it already loaded myModel the second time you request it and simply gives you the same object again :-) Incidentally, if you have more than one content manager, the default behavior is that requesting the same asset from two different managers will result in the asset being loaded into memory twice.
