  • Desktop PC does not power up on power button

    - by hIpPy
    When I press the power button on my desktop, it does not power up completely. Before I press the power button, I see lights on the motherboard. Everything is normal. On power button press, the fans on the cpu, graphics card and motherboard start to spin a little for a second or two and then they stop. No beeps during this process. It has been doing this for a while now but it used to start up after some trials. Once it starts up, I have NO issues at all like random shutdowns so it is not an issue with OS. I'm just guessing here but it seems as if the PSU (Antec TP2-550ATX) is dying out and does not have enough power now - just a guess. It's an old desktop assembled in 2005 but I have maintained it well. Any ideas? Please help. Thanks. Below is the complete configuration. DFI LAN-Party UT NF4 Ultra-D 6/23 {6.70}, Evercool EC-VC-RE 41/47C, AMD Opteron 170 2.0GHz {1.3.2.16} 1.312V 36/41C, ThermalRight SI-120, Panaflo 120×38mm OCZ Platinum 2×1GB 200MHz 2.66V 3-3-2-7 1T XFX 7800GTX 256MB 475/1250MHz {91.31}, Zalman VF900 Cu led 41/56C WD Caviar 320GB 7200RPM 16MB SATA 3Gb/s Antec TP2-550ATX Antec P180 WinXP sp2 KB896256 Logitech MX310 Razer Mantis Speed BenQ FP91G+ 19" LCD 8ms DVI Creative Audigy2 ZS {4.42} BenQ DW1640 Logitech z-5300e 5.1 280W Legend: Driver versions: {} User settings: [] Voltage: V Wattage: W Temperature: C (Celsius) min/max

  • How VerticalOffset changes when Scrollable height changes while having list inside a list

    - by Prakash
    I am making a WP7 app which has a Listbox of UserControls. Each UserControl has an ItemsControl and Button(for getting more results). On click of the button the ItemsControl items will be increased by 5 or 10. Now on clicking on the GetMore button of any of the usercontrols except the first or last, there will be an increase in Scrollable height(Total height of the listbox) of the ListBox but the VerticalOffset(position of scrollbar from top) of the ListBox remains same. Now the problem I am facing is that the Vertical Offset is not absolute but relative to Scrollable Height. So the content being viewed till then will be changed basing on the new value of ScollableHeight. I want to know the relation between them, so that I can do some math and set the VerticalOffset value. I have added some dependency properties on VerticalOffset and ScrollableHeight through which I can get the events when any of them is changed. Also trying to use them to readjust the VerticalOffset. Any suggestions or corrections are highly appreciated.

  • Connect to an elevated COM server from a non-elevated process

    - by JS Bangs
    We have a program which launches a child process that hosts a local COM server, which for various reasons must be launched elevated. Everything works fine so long as both the parent and the child process are elevated. However, we also want to run when the parent process is non-elevated. Launching the child process results in a UAC dialog (which is acceptable), and the child appears to start correctly and successfully calls CoRegisterClassObject. However, the parent process gets REGDB_E_CLASSNOTREG when calling CoCreateInstance with the same CLSID. I assume this is some sort of permissions issue. How can I register my class in the elevated server to allow it to be called from a non-elevated process.

  • WriteableBitmap failing badly, pixel array very inaccurate

    - by dawmail333
    I have tried, literally for hours, and I have not been able to budge this problem. I have a UserControl, that is 800x369, and it contains, simply, a path that forms a worldmap. I put this on a landscape page, then I render it into a WriteableBitmap. I then run a conversion to turn the 1d Pixels array into a 2d array of integers. Then, to check the conversion, I wire up the custom control's click command to use the Point.X and Point.Y relative to the custom control in the newly created array. My logic is thus: wb = new WriteableBitmap(worldMap, new TranslateTransform()); wb.Invalidate(); intTest = wb.Pixels.To2DArray(wb.PixelWidth); My conversion logic is as such: public static int[,] To2DArray(this int[] arr,int rowLength) { int[,] output = new int[rowLength, arr.Length / rowLength]; if (arr.Length % rowLength != 0) throw new IndexOutOfRangeException(); for (int i = 0; i < arr.Length; i++) { output[i % rowLength, i / rowLength] = arr[i]; } return output; } Now, when I do the checking, I get completely and utterly strange results: apparently all pixels are either at values of -1 or 0, and these values are completely independent of the original colours. Just for posterity: here's my checking code: private void Check(object sender, MouseButtonEventArgs e) { Point click = e.GetPosition(worldMap); ChangeNotification(intTest[(int)click.X,(int)click.Y].ToString()); } The result show absolutely no correlation to the path that the WriteableBitmap has rendered into it. The path has a fill of solid white. What the heck is going on? I've tried for hours with no luck. Please, this is the major problem stopping me from submitting my first WP7 app. Any guidance?

  • How to prevent Visual Studio setting my default font sizes in an inherited control

    - by Colin
    I have a base class for all my textboxes and I want to set the default font in that class. So I started with this: public partial class MyTextBox : TextBox { public WmlTextBox() { InitializeComponent(); //Font for the whole application can be altered in the Appearance class Font = new Appearance().TextBoxFont; } } I then stripped out all the code in the form that was setting the font of the textboxes. Of course this worked fine until I altered an item on the page. Visual Studio picked up the default font for the application (set in the Appearance class), and generated code in the designer for all TextBoxes to set it to that specific font. How can I stop visual studio from generating code from my default font? I want to allow the developers to change the property, but I want to set the default font centrally.

  • Help me understand this C code

    - by Benjamin
    INT GetTree (HWND hWnd, HTREEITEM hItem, HKEY *pRoot, TCHAR *pszKey, INT nMax) { TV_ITEM tvi; TCHAR szName[256]; HTREEITEM hParent; HWND hwndTV = GetDlgItem (hWnd, ID_TREEV); memset (&tvi, 0, sizeof (tvi)); hParent = TreeView_GetParent (hwndTV, hItem); if (hParent) { // Get the parent of the parent of the... GetTree (hWnd, hParent, pRoot, pszKey, nMax); // Get the name of the item. tvi.mask = TVIF_TEXT; tvi.hItem = hItem; tvi.pszText = szName; tvi.cchTextMax = dim(szName); TreeView_GetItem (hwndTV, &tvi); //send the TVM_GETITEM message? lstrcat (pszKey, TEXT ("\\")); lstrcat (pszKey, szName); } else { *pszKey = TEXT ('\0'); szName[0] = TEXT ('\0'); // Get the name of the item. tvi.mask = TVIF_TEXT | TVIF_PARAM; tvi.hItem = hItem; tvi.pszText = szName; tvi.cchTextMax = dim(szName); if (TreeView_GetItem (hwndTV, &tvi)) //*pRoot = (HTREEITEM)tvi.lParam; //original hItem = (HTREEITEM)tvi.lParam; else { INT rc = GetLastError(); } } return 0; } The block of code that begins with the comment "Get the name of the item" does not make sense to me. If you are getting the listview item why does the code set the parameters of the item being retrieved? If you already had the values there would be no need to retrieve them. Secondly near the comment "original" is the original line of code which will compile with a warning under embedded visual c++ 4.0, but if you copy the exact same code into visual studio 2008 it will not compile. Since I did not write any of this code, and am trying to learn, is it possible the original author made a mistake on this line? The *pRoot should point to HKEY type yet he is casting to an HTREEITEM type which should never work since the data types don't match?

  • GridView's ItemContainerStyle and selection states

    - by Roberto Casadei
    I'm trying to change the appearance of gridview items when they are selected. (Before, I used a trick with an IsSelected property in the ViewModel object bound to the containing grid and a bool-to-color converter, but I recognize that it is bad) To do so, I do: <GridView ItemContainerStyle="{StaticResource GridViewItemContainerStyle}" ...> ... and <Style x:Key="GridViewItemContainerStyle" TargetType="GridViewItem"> <Setter Property="Background" Value="Red" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="GridViewItem"> <Grid> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="Normal"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(Grid.Background)" Storyboard.TargetName="itemGrid"> <DiscreteObjectKeyFrame KeyTime="0" Value="Black"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> </VisualStateGroup> <VisualStateGroup x:Name="SelectionStates"> <VisualState x:Name="UnselectedSwiping"/> <VisualState x:Name="UnselectedPointerOver"/> <VisualState x:Name="Selecting"/> <VisualState x:Name="Selected"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(Grid.Background)" Storyboard.TargetName="itemGrid"> <DiscreteObjectKeyFrame KeyTime="0" Value="White"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="SelectedSwiping"/> <VisualState x:Name="Unselecting"/> <VisualState x:Name="Unselected"/> <VisualState x:Name="SelectedUnfocused"/> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <Grid ... x:Name="itemGrid"> <!-- HERE MY DATA TEMPLATE --> </Grid> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> When I run the app, the items are Black (as in the "normal" state). But selecting them does not turn them into White. Where am I wrong? Moreover, it there a way to set "ItemContainerStyle" without having it to "overwrite" the "ItemTemplate" ???

  • Will NKDbgPrintfW be compiled to nop in release build?

    - by Johann Gerell
    I know about and have used the macros DEBUGMSG, RETAILMSG, ERRORMSG, that all take a condition parameter. For general formatted debug output, though, I want to use ::NKDbgPrintfW directly and wonder if someone knows if it compiles to a nop in optimised release builds or if my own macro wrapper around it with #ifdef DEBUG is still needed?

I would like to bind the foreground color of the Items of the ListBox to whether the item is the one selected in the list box, i.e. I would like the Item's foreground color to be Black if not selected and White if the item is selected. How can it be done? Thanks,

  • How to disable WM6.5.3 gestures?

    - by Duncan Watts
    I am working on a .NET 2.0 application targetting the WM5 SDK, what is the correct way to disable the gesture functionality when running on a WM6.5.3 device that only affects the forms I am using? This is causing an issue when I have a signature capture control inside a tab control - when the signature is entered it's quite common for the tab control to switch tabs as WM6.5.3 picks it up as a gesture. I don't want to disable the gesture functionality device wide, nor can I upgrade the application to target the WM6.5.3 SDK as it still needs to work on older devices. Cheers
