Splitter Panel Resize

Jeffrey Walton20-Nov-07 20:30

Hi All,

I have a horizontal Splitter, for which I would like the top panel to remain 20 pixels in height. I do this because I have a containter on it, and I overide the OnPaint method. It is being painted as a band similar to that of Disk Defragmentor.

Any ideas on how to disable a Splitter panel from being resized? I've locked the controls (it stops me from resizing it at design time); I've set SplitterFixedPanel = Panel1 [1,5]; and I've set SplitterDistance to the same as design time [2]. Overriding Moving events causes a runtime error when I try to force the control's height back to the desired height through the Height property [3, 4]. From [5]:

Use the Panel1 property to configure the left panel of a vertical SplitContainer or the top panel of a horizontal SplitContainer. For example, you can specify the minimum size of the panel by changing the value of the Panel1MinSize property, set the FixedPanel property to Panel1 so that the panel remains the same size when the container is resized, or you can get or set the panel's BackgroundImage and BackgroundImageLayout properties.

Nothing stops this damn thing from moving. Any help would be appreciated.

Thanks,
Jeff

Hi Guys. I am writing a piece of code to extract data from an Access DB into a CSV file. Now, i want to inlcude int he below piece of code only records that are set to a certain value in a column. I.e. I want to extract only the records in the "EXPORTED" Column that have a value of 0. How do I do this in the below code? I think I masy have to add this in the foreach line but I am not sure how to do this. Can somebody please help me with this? I.e. I want to say,

foreach (DataRow dr in dt.Rows WHERE ["Exported"] == 0).

I am sure this is incorrect. How do I structure this correctly?

//Write all records in the DB
foreach (DataRow dr in dt.Rows)
{
    for (int i = 0; i < iColCount; i++)
    {
        if (!Convert.IsDBNull(dr[i]))
        {
            sw.Write(dr[i].ToString());
        }
        if (i < iColCount - 1)
        {
            sw.Write(",");
        }
    }
    sw.Write(sw.NewLine);
}

sw.Close();

Hi,
here in this loop you have to check for tab control abd then you have to again loop for controls in tab control. like this

foreach(Control c in this.Controls)<br />
if(c is TextBox)<br />
( c as TextBox).Clear(); <br />
if(c is TabControl)<br />
 {<br />
 foreach(Control c1 in this.Controls)<br />
if(c1 is TextBox)<br />
( c1 as TextBox).Clear(); <br />
<br />
 }<br />

Graphing Control

We are going to need to go on a field trip for this one.

Go to: http://finance.google.com/finance?q=.DJI%20.IXIC%20.INX

If that link doesn't work you can go to: http://finance.google.com/finance and click on the graph
on the right side of the page under "Market Summary"

What you see when you get there is a brilliant little flash applet that creates a real-time interactive graph. Play around with it a little. You can grab the sliders at the bottom of the graph and adjust the period of time that you want to look at. Pretty nifty.

I would love it if I could find either a .Net, MFC, Java (or even Flash) control/component/module/library that would allow me to have this sort of functionality in a stand alone application. The one at the link is made by Google apparently but I don't think they have released the source.

I have seen tons of graphing/charting libraries (nevron, dundas, dotnetcharting, ZedGraph, ChartFX...). None of them provide this interactive capability. Does anyone out there know of such a thing? I'll go commercial or free which ever provides the functionality.

If not, someone should make one. It's money in the bank.

I found the flash code for the applet on the Google finance site. They call it a time-series graph and it is written in actionscript 3.

http://code.google.com/p/time-series-graph/

I don't know how to make standalone apps that embed flash so I am still looking for a .Net or MFC control. If anyone knows of a way to embed flash into a .Net or MFC application. I would love to know about it.

With SQL. The drop list is irrelevant, the way you update a database is always the same,

If you have selected the 5th item and the 1st is being shown as selected, odds are this is an ASP.NET question and you're databinding the control in page load on postback.

I don't know that how are you binding your dropdownlist. But the proper way is to bind the dropdown as valuefield property is set by stateid and displayfield should be set by name of state. Now get ddl.selectedvalue and pass it to database and update by the help of value field. Hope this will help you.

I guess .PerformClick() is the answer!

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
