Can anyone suggest me how to keep the scroll at the same position when the child window gets activated... thanks in advance..

May i know in which blog i need to ask this question..?

hi. Please see the following code. HistoryData is also a dataset..

string strExpression = "Date >= '1/2/2009' And Date <= 2/2/2009"

Dataset dsData = HistoryData;
DataSet dsNew = new DataSet();

DataTable dt = dsData.Tables[0];

DataRow dr = dt.Select(strExpression);

in the above code it gives the filtered rows into dr. but i need to apply the select command to dataset and copy the filtered data into new dataset. Please help me..

Hi. I need to regitser a UltraToolbarManager(Infragestic Control) to CAB SCSF inorder to add Toolbar items at runtime..

Hi Everyone, I'm using SplitContainer, now i need to Fill Panel2 with Red Color Background Without using Panel2 paint event how to Draw it.

[Message Deleted]

thank you Simon, i ll check it..

hi Christian Graus. I searched in the net, i got some solution but it is not using the bitmap to draw, but i have draw a curve on bitmap to load it to picturebox control. so i need to know how to use bitmap for Print Preview. please reply

hi.. I have drawn a Sine wave on a bitmap using GDI+, now i need to give an option to Print the waveform.. First it should display the print preview then it as to print the Waveform.

Can u tell me how to use Chart Control in C#.

hello everyone.. Good evening..:)) I' doing an application with GDI+ to draw sine wave... float fltZoomF = 1; Graphics gPanel2Graphics = this.CreateGraphics(); gPanel2Graphics.Clip = new Region(Panel1.ClientRectangle); gPanel2Graphics.ScaleTransform(fltZoomF, 1F);
if i run my application the sine wave fits correctly to the screen size, but if i try to zoom by increaseing the fltZoomF value to 2.. how much pixel or percentage it ll going to increase the width of the graph.. im using horizontal scrollbar to scroll, how do i proceed to increase the ScrollBar maximum value while the fltZoomF is changed to 2. please help me..

hi everyone I'm using GDI+ concept to draw a multiple sine waves in a panel, It is having more flickering.. if any Forms/window come above/infront of the panel that part of the region is again redrawn. is there any way to avoid re-drawing of that region by invalidating that region or something. or Can u suggest me is it good to switching from GDI+ to anyother concept like directx..

some one had deleted me message.

that's a great idea, in fact it is required to draw only part of the sine wave, but how to find which are those points that i need to consider.. int intLenght = 200; PointF[] pf = new PointF[intLenght]; for (int intI = 0; intI < intLenght; intI++) { int intHeightOffset = 250; if ((intI%10) > 5) { pf[intI] = new PointF(intHeightOffset + intI, (intI % 10) + intHeightOffset); } else { pf[intI] = new PointF(intHeightOffset + intI, -(intI % 10) + intHeightOffset); } } Graphics gps = this.CreateGraphics(); gps.DrawCurve(new Pen(Color.DarkBlue), pf); if i select middle of the graph, from which point's of the array i hv to take to redraw the sine wave..? pls dont mind, i need ur help..

Sorry i ll explain my question clearly. 1) I have drawn a Sine Wave using Graphics.DrawCurve(..); 2) Now i need to capture (X1,Y1) and (X2, Y2) Vaues on mouse down and mouse Up function, where I'm selecting a particular region of the sinusoidal wave. (may be upper half cycle). 3) So now i have the values, but i dont know how to enlarge only selected region in GDI+ C#.. plsssss help me.

I have to expand both Sine wave as well as with(in terms of pixels) of the bitmap. can i have sample code..

hi Everyone I Have drawn a Sine wave using GDI+ in C# windows application, now i need to know how to zoom the Selected region.. can anyone help me? plssssss

thanks leppie. I have forgotten that, I'm New to C#. Sorry.. I ll try to Learn things as early as possible.. thanks :)
