How To Delete Multiple Selection of Rows in a Listview Control ? danielwinata24-Jun-07 17:06 danielwinata 24-Jun-07 17:06  Hi all, I think it's quite easy to delete single selection of rows in a listview. I usually do this : DELETE FROM Purch WHERE PurchID LIKE '" + lvPurch.Items[lvPurch.FocusedItem.Index].SubItems[0].Text + "' " I wonder how to delete multiple selection of rows in a Listview Control ?

Sathesh Sakthivel24-Jun-07 17:34 Sathesh Sakthivel 24-Jun-07 17:34  Try with this Code: int CMultipleRowDeleteView::DeleteSelectedRowsFixed(void) { int nSelRows = GetListCtrl().GetSelectedCount(); if(!nSelRows) return(0); int* pnArrayOfSelRows = new int[nSelRows]; if(!pnArrayOfSelRows) return(0); int nTemp = nSelRows; POSITION pos = GetListCtrl().GetFirstSelectedItemPosition(); int i = GetListCtrl().GetNextSelectedItem(pos); while (i != -1) { nTemp = nTemp-1; pnArrayOfSelRows[nTemp] = i; i = GetListCtrl().GetNextSelectedItem(pos); } for(int j=0; j < nSelRows; j++) { GetListCtrl().DeleteItem(pnArrayOfSelRows[j]); } delete(pnArrayOfSelRows); pnArrayOfSelRows = NULL; return(1); } Hope this will Help you.

Problem: We've got a complex User control, which is organized in 5 classes: Shape Corner Color Designer UiTypeEditor in "Color" we've got around 20 Properties indicating Different Brushes properties based on fixed value ranges.(PathBrush Distance from Center,a Linear Gradient property based on an Enum which let User choose only stepped values as "Top,TopLeft" etc. as position for colors..) We got in Corner,something similar to "Color class" in which we define all proportions and values only for having an independent object which act as corner for a rounded rectangle. In the "Shape Class" we have finally a Graphics access with the method for creating and colorizing our Graphic UserControl. We reached the ability to Have a "Color" Category in PropertyGrid,but ONLY using all I explained in first class in file. We tried using PostFilterProperties driven by a "FillingType" property(PathGradient,LinearGradient,Solid etc..)If we select from one of those values we're able to show ONLY needed properties for type selected.(Ex. If Master Property is set to "Solid Fill Type",then Properties under It will be only Color Solid and Transparency(Alpha)....If We select "LinearGradient",all Solid Fill Values disappear and appear in propertygrid ColorGradientA and ColorGradientB and so on for textureFill etc..)All that Works but: For viewing result of switching we need to dispose control and re-drop from toolbox,we are NOT YET ABLE to expose to property grid something is coming from other classes in same namespace(We got ALL Geometric values and methods in "Shape Class" and we would like to "pass" as fillpath(argument) Our FillType selected by PropertyGrid.We tried Invalidate(),Refresh(),but nothing,and ever with First class.We would like to be able to public class Shape { /// only generic snippet here for example... public int var; public int CornerRadius { get{...} set{...} } } //here real snippets public class Color { public static string[] PropertiesToRemove = new string[13]; public enum FillTypeEnumerator { Solid, LinearGradient, PathGradient, Texture } FillTypeEnumerator FillTypeValue = FillTypeEnumerator.Solid; [Category("Color")] public FillTypeEnumerator FillType { get { return FillTypeValue; } set { FillTypeValue = value; switch (FillTypeValue) { case FillTypeEnumerator.Solid: PropertiesToRemove.SetValue("LinearGradientTransparencyA", 0); PropertiesToRemove.SetValue("LinearGradientTransparencyB", 1); PropertiesToRemove.SetValue("LinearGradientColorA", 2); PropertiesToRemove.SetValue("LinearGradientColorB", 3); PropertiesToRemove.SetValue("LinearGradientPositions", 4); PropertiesToRemove.SetValue("PathGradientCenterColorTransparency", 5); PropertiesToRemove.SetValue("PathGradientCenterColor", 6); PropertiesToRemove.SetValue("PathGradientSurroundColor", 7); PropertiesToRemove.SetValue("PathGradientSurroundColorTransparency", 8); PropertiesToRemove.SetValue("PathGradientFocusDistance", 9); PropertiesToRemove.SetValue("PathGradientCenterPosition", 10); PropertiesToRemove.SetValue("TextureImage", 11); break; case FillTypeEnumerator.LinearGradient: PropertiesToRemove.SetValue("SolidTransparency", 0); PropertiesToRemove.SetValue("Solid", 1); PropertiesToRemove.SetValue("PathGradientCenterColorTransparency", 2); PropertiesToRemove.SetValue("PathGradientCenterColor", 3); PropertiesToRemove.SetValue("PathGradientSurroundColor", 4); PropertiesToRemove.SetValue("PathGradientSurroundColorTransparency", 5); PropertiesToRemove.SetValue("PathGradientFocusDistance", 6); PropertiesToRemove.SetValue("PathGradientCenterPosition", 7); PropertiesToRemove.SetValue("TextureImage", 8); break; case FillTypeEnumerator.PathGradient: PropertiesToRemove.SetValue("LinearGradientTransparencyA", 0); PropertiesToRemove.SetValue("LinearGradientTransparencyB", 1); PropertiesToRemove.SetValue("LinearGradientColorA", 2); PropertiesToRemove.SetValue("LinearGradientColorB", 3); PropertiesToRemove.SetValue("LinearGradientPositions", 4); PropertiesToRemove.SetValue("TextureImage", 5); PropertiesToRemove.SetValue("SolidTransparency", 6); PropertiesToRemove.SetValue("Solid", 7); break; case FillTypeEnumerator.Texture: PropertiesToRemove.SetValue("LinearGradientTransparencyA", 0); PropertiesToRemove.SetValue("LinearGradientTransparencyB", 1); PropertiesToRemove.SetValue("LinearGradientColorA", 2); PropertiesToRemove.SetValue("LinearGradientColorB", 3); PropertiesToRemove.SetValue("LinearGradientPositions", 4); PropertiesToRemove.SetValue("PathGradientCenterColorTransparency", 5); PropertiesToRemove.SetValue("PathGradientCenterColor", 6); PropertiesToRemove.SetValue("PathGradientSurroundColor", 7); PropertiesToRemove.SetValue("PathGradientSurroundColorTransparency", 8); PropertiesToRemove.SetValue("PathGradientFocusDistance", 9); PropertiesToRemove.SetValue("PathGradientCenterPosition", 10); PropertiesToRemove.SetValue("SolidTransparency", 11); PropertiesToRemove.SetValue("Solid", 12); break; } this.Invalidate(); } } //SolidFill int SolidTransparencyValue = 255; [Category("Color")] [Editor(typeof(TrackBarEditor), typeof(UITypeEditor))] public int SolidTransparency { get { return SolidTransparencyValue; } set { SolidTransparencyValue = value; this.Invalidate(); } } ColorDialog FillSolidColorDialog = new ColorDialog(); [Browsable(true)] [Category("Color")] public Color Solid { get { return Color.FromArgb(SolidTransparency, FillSolidColorDialog.Color); } set { FillSolidColorDialog.Color = value; this.Invalidate(); } } } } Why for Example I cannot see in property Grid "Solid" Property and I'm be able to see ONLY Shape properties? What we have to do?IExtenderProvider? What needs PropertyGrid in System.Reflection for searching also in 2nd,3rd,n class?Service,a CustomDesigner? Is possible Idictionary is filled ONLY by properties of 1st class? Simply re-populating the "Default Designr PropertyDescriptorCollection I would be able to...seems not... Please we're in the middle of the Sea..try to Win this challenge! Thanks to all for Patience!

Also, how can you make it so that the minimize, maximize, and close buttons are disabled on the form? ----- Note: *** Never give me an answer have anything to do with Visual Studio.

There are CP articles on making your app's icon appear in the system tray. max29297 wrote: Also, how can you make it so that the minimize, maximize, and close buttons are disabled on the form? You can remove them entirely in the designer, if you remove just minimise or just maximise, then it will disable instead of being removed. Oh - sorry. You're not using visual studio for some bizarre reason ( the C# express edition is free ). The form has properties which you can set manually, I believe they are called MinimizeButton, MaximizeButton and the close one refers to the entire menu, I forget it's name.
