Hi,
Maybe I'm not in the right forum. If so, accept my apologies and please re-direct me.
I am trying to install 'MS Visual Web Developer 2010 Expres' Actually I first installed Web Matrix, found it crap, and decided on the Next. First un-installed Web Matrix. Tried to install Visual Web Developer 2010 Express, it started with wanting to install SQL Express. Failed First, (After 2 hours) ostensibly because my disk was compressed.(Could that not have been detected early during setup, if that's a problem) Cloned the disk to a Larger One,usinf EaseUS, Undid the compression( as far as I could, went throuhg All Directories)(Some Files could not be Decompressed because they where in Use).
Tried Again. Got a message box: 'Installation Failed\nThe Version of SQL Express you are installing is Older than the version you have.'
Tried to use Windows Installer to uninstall. Started First to Last for SQL Server products,as listed. -:Fails on 'Cannot Uninstall this Component because other components are depending on it.'
Cloned the disk again to another disk, and started manually uninstalling components from the bottom to the Top, using Windows Uninstaller in other following orders, got messages:- To Uninstall This Component, you need XXXAXP DLL.
Rethorical Question, Why does a Microsoft Product not meet the Ms Uninstal/Failure to install specification written by microsoft themselves.
Question2, the Real question,
Where do I go from Here!
any help appreciated
Regards,

Well we are stabbing in the dark now so try installing Web Express on one of the uncomrpessed disks. Sounds like you now have SQL Express installed.

The computer doesn't know how to draw a map of a specific country by itself, that information is not embedded into your PC and will have to be provided by you.
You could import a picture, show it in a PictureBox, and have the user click it. You would than have to translate the location of the pixel to a known country. The easiest way to do that is by coloring different regions with different colors; once you know the pixel where the user clicked, you know what color, and hence, what region.

Hi
Thanks for your guideing,
I used this way that you suggest,
but,I don't want to use this way,
I want that Program,itself,draws map on form,& finds out that the user where clicked,
|
|
|
|
|
Them you are going to have to draw the map, and maintain a list of polygons that match the outlines of the regions. Then, when the user clicks on the map, you do a point in polygon check to see if they've clicked in the region.
|
|
|
|
|
if you want to draw it yourself, you'll need a data source that contains all the elements to draw, mostly these are area's (polygons), lines (polylines) and dots, each area or line or dot has certain charactiristics like water, road, ... if you have all that you'll also need to find a way to link all elements and to zoom in/out the map.
In short (I probably forgot to mention most of the stuff anyway) you'll need to find a provider for the geographical stuff. For a fee they'll provide you with some assemblies you can use as well as the database with all information in it (and with updates if necessary).
hope this clarifies things for you.

Hi,
Thanks very much!
I want to use the Region class for Drawing Map on form & for Drawing countries on Map,
"Region" can helps me for this program?
Are there another ways for this program?
Are there a classes or components for creating & Drawing Map?

Mahtab777 wrote: "Region" can helps me for this program?
It might, if you have all the borders stored as points somewhere.

Not in the Framework; you'll either have to write them or look for something similar.

What I meant to say is, that if you want to draw a map you probably don't have the know-how (nor do I for that matter) to do it yourself within a reasonable amount of time. Normally such a task takes a lot of design and many resources to do it. If you need a map quickly you probably need a third party component (google maps perhaps?) or as someone already suggested a picture.

this is a really boring question so sorry in advance...
i am writing a pdf viewer (don't ask why or i'll have to kill you) and have most of the code working BUT the scrollbars are driving me slightly nutz
i have the picturebox control set to autosize inside of a panel set to autoscroll
when i set the (generated) image into the picturebox i get a vscrollbar (as expected) and no hscrollbar (again as expected because i resize the form client area to fit the width of the page i'm displaying)
when i shrink the window (with the mouse) i would have expected the hscrollbar to show up but no .. it doesn't
i do catch the form resize event and if the the client area is wider than the page being displayed i change the picturebox size mode to centered so it looks nice
otherwise i have tried all the 217 posts i have read on the net and they all say the same thing and they all don't work for me here
any help greatly appreciated

How about dropping your PictureBox (full size) in a Panel, and let the panel worry about scrolling?

With the picturebox as large as the picture is, so it can scroll inside it's container?
The code below worked for me; is your picturebox by any chance smaller than it's container?
public partial class Form1 : Form
{
Panel somePanel;
PictureBox somePictureBox;
public Form1()
{
InitializeComponent();
this.somePanel = new Panel()
{
Dock = DockStyle.Fill,
AutoScroll = true,
};
this.somePictureBox = new PictureBox()
{
Size = Screen.PrimaryScreen.WorkingArea.Size,
BackColor = Color.Blue
};
this.somePanel.Controls.Add(somePictureBox);
this.Controls.Add(this.somePanel);
}
}

eddy thnx for the reply again
i see that you are making your picturebox a fixed size yes?
mine has to change as they zoom in and out of the "image" as well as scroll
i have it kind of working (god only know how) but i know the code is horrendous as it has a bunch of "magic fudge factors" in it as i am not familiar enough with .NET / C# and graphics etc
i think i am not getting the actual screen dpi for the bitmap dpi, as that means i need to do some rather opaque calcs on the scaling factor for the pdf renderer and and and... *sigh*
i think if i had a fixed size picturebox the code would work properly as that is a "trivial" case yes?

Yup

It should be. You could try putting the PictureBox in a fixed-size container, and have that in a scrollable Panel again.

hehe yah no... not in my world
right now it is working but i *know* parts of it are not written properly so i have to figure those bits out and make them right
i have a proof of concept that is *good enough* to show the general approach and UI work but that sure as hell isn't a "product"
last 10% of the code == 90% of the time
*sigh*
anyways i will be asking embarrassingly dumb questions in the next few days i'm sure but that's what 9yrs of web dev does for a programmer

There's no such thing as a dumb question, only posts without PRE tags.

my current code is
private void Gallery_Load(object sender, EventArgs e)
{
TestAppDBDataContext db = new TestAppDBDataContext(AppConn.AppConnection);

Hi experts,
in my application there are two controls DragSource and DragDestination. User can drag objects from DragSource and drop them onto DragDestination.
Now I would like to have some kind of no-drop-zone from DragDestination's border 20 pixels to the inside. Like a frame but within the control, not around it.
DragEnter should fire when the mouse pointer reaches the inner, drag-allowed area.
How can I set the drag area differing from the overall control area?
Ciao,
luker

There is no property or function to set the area for a drag and drop operation inside a control.
If you want the DragEnter event raised only within certain borders, you'll have to get creative with control layouts and surround the control that is accepting the drag and drop with other controls, like Panels, that are painted the same color as your target drop control to creat the border.
Another option is to allow the DragEnter, DragHover, DragDrop and DragLeave events to fire as normal and just check the coordinates of the mouse inside your event handler to determine if anything should be done.

Hi,
Handle the DragOver event on the target and set the DragEventArgs.Effect value. The DragDrop event is suppressed when DragEventArgs.Effect is set to None.
private void panel2_DragOver(object sender, DragEventArgs e) {
Rectangle subRect = Rectangle.Inflate(panel2.ClientRectangle, -20, -20);
Point p = panel2.PointToClient(new Point(e.X, e.Y));
Boolean withinSubRect = subRect.Contains(p);
if (withinSubRect) {
e.Effect = DragDropEffects.All;
} else {
e.Effect = DragDropEffects.None;
}
}
Alan.

Hi,
For the below xml, I would like to get the parent and level of the entity node. For example, for the Business entity, token value should be BUSINESS; desc value should be Business News; parent should be PROD; level should be 1. From the below code, I'm getting token and desc values. Kindly guide me to get parent and level values. Thanks in advance.
foreach (XPathNavigator book in topicsXml.CreateNavigator().Select("//Entity"))
{
string token = book.SelectSingleNode("Token").Value;
string desc = book.SelectSingleNode("Description").Value;
string parent = ?
string level = ?
}
<CodeList>
<Entity>
<Token>PROD</Token>
<Description>prod</Description>---->level 0
<Entity>
<Token>BUSINESS</Token>
<Description>Business News</Description>---->level 1
<Entity>

For the parent node, you can use .. to navigate upward the xml tree (like as it where a directory).
Using your Example, string parent = book.SelectSingleNode("../Token").Value; will get you the parent token of the current entity.
For the depth, you could try to count the number of entity parent nodes, like this:
string level = book.SelectSingleNode("count(ancestor::Entity)").Value;
I don't know if that will give you a 0-based or a 1-based value, you will have to do some tests.
|
|
|
|
|
string parent = book.SelectSingleNode("../Token").Value;
This returns the inner data of xml
value of parent: "PRODprodBUSINESSBusiness NewsCOSCompany NewsANAAnalyst RatingsANAMOVESAnalyst Ratings, Estimates and Target Price ChangesANACHANGEAnalyst Rating ChangesANACUTAnalyst DowngradesANACUTEVTAnalyst Ratings Cut Events, AnnouncementsIPIntellectual PropertyCOPYRIGHTCopyrightsDRGPATENTDrug Patents"
string level = book.SelectSingleNode("count(ancestor::Entity)").Value;
This line thrown exception, "Expression must evaluate to a node-set."
I hope I'll succeed in getting level by using ancestor, by giving correct syntax.
Please let me know how to get the parent value. Thank you
