I think your only opportunity is to register to the MouseEnter and MouseLeave event of the control and inside the event handlers call the ToolTip.Show or ToolTip.Hide method, respectively.

Hi,

I have done some custom tooltip stuff (inspired by some CodeProject articles),
with a lot of SendMessage, but I am not aware of any TTM_xxx message to specify the ON time,
so mine too disappear after some 5 seconds.

TreeView images not showing correctly

Coders... I have assembled a basic TreeView with several nodes. When I add icons using the ImageList class, the icons are not displaying correctly. It appears as if the icons are not transparent yet when used in the Tool Bar or Menu Bar they appear correctly. They look all fuzzy and/or blotchy no matter what size or depth the icon is that is applied.

Thoughts or ideas?

Have you set the ImageList.ColorDepth property to ColorDepth.Depth32Bit? Also, are the images the same size as the ImageList.ImageSize property?

Thanks for the info, I re-reviewed the settings and then like a ton of bricks it hit me... I was trying to use 32x32 and 24x24 icons. When I got some 16x16 icons they worked perfect... brain process overflow, should have caught that right away.

Simple Databinding to Datarow - values not updating???

TheTinSoldier5-Feb-07 9:29

Hi, I have a loop that is populating label controls from a Datatable. If I simple bind the datarow to the labels' Text property, when I update the Datatable I expected the changes to be reflected in the label. This is true if I bind the the table directly.

// this shows the correct values but they don't update when I update the data in the table<br />
...<br />
templabel.DataBindings.Add("Text", dt.Rows[i], "state");<br />
...

// when I bind directly to the table, updating the table does reflect the changes. But this option is no good as all my label controls have the same values.<br />
...<br />
templabel.DataBindings.Add("Text", dt, "state");<br />
...

Thanks!

Updating multiple tables

Hi!

I was wondering how to write update and insert queries for two table simultaneously. I'm getting some rows from two table with OUTER JOIN LEFT into one dataset. The second table has a primary key which is a row from the first one and their must be a value in the first table. So second table gives me mostly NULLs value and that's okey. But I can't add a record to second table if I firsty don't add particular value into first one. Right now I'm able to insert and update data, but I would like to right single query.

PS. Sorry for my English.

Hard to understand without an example.

Sounds to me like you need to use a stored procedure with as many parameters as necessary to do work. This could then do any CRUD on parent table necessary and then appropriate CRUD to child table.

Another alternative (may not fit as I don't know your structures) is to create method on dataset that can be called to do updates. This method would do appropriate call to parent table for modified record(s) and then do appropriate calls to child table for modified record(s).

I did something similar to the second answer but had to add additional code to support transactions within the code generated for the typed dataset. I could genericize my code and post it if it might be helpful.

Thanks,

Ware

Firstable thank you for fast reply.

I just find out that it's impossible to a column in my bigger table is in the second one is a record with the same PK.

Tables looks like this. First one has more then 10 column, but it isn't necessary. I has a primary key so let's call it ID. The second table is much smaller and has additional data. And it has the same primary key column which is foreign key as the same time. I noticed that I cannot modify this column in neither of those tables if it exists in both...

The better design would be the following if you can go that way.

Table1
=========
Id - PK
Data1
Data2
...

Table2
=========
Id - PK
Table1Id - FK
AddlData1
AddlData2
...

Thanks,

How to set Property description?

Hi Guys

How to set a description for a property in a class? I have found some articiles talking about method description using summary tag. summary.../summary. But it doesn't seem to be working for properties.

Can any one help me on this?

Thanks in advance.

Muthu.

You do use the summary tag. This is an example:

/// <summary;>
/// Get or set the Id.
/// </summary;>
/// <remarks;>
/// The Id must be a positive value.
/// </remarks;>
public int Id
{
  get { return _id ; }
  set { _id = value; }
}

the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer

Deja View - the feeling that you've seen this post before.

I'm sorry. I didn't mention that it is for intellisense description.
I tried both ///summary and System.ComponentModel
I didn't get intellisense description in both cases.

Thanks

Muthu.

The properties shown by Visual Designer are not from the /// tags, but from
the Description attribute, which is unfortunate, since this makes me write
the same thing twice, as in:

using System.ComponentModel; // Category, Description

/// <summary>
/// Gets or sets the initial color of the overlay.
/// Use Color.Transparent to make it always transparent, or
/// some opaque color to get the scratch functionality.
/// </summary>
[Category("ScratchPanel"), Description("Gets of sets the initial color of the overlay. "+
"Use Color.Transparent to make it always transparent, or "+
"some opaque color to get the scratch functionality.")]
public override Color ForeColor {
...
}

Yes you are right, there is an issue. I havent noticed this before:

Visual Studio 7.1 does not show Intellisense for properties (it does for methods e.a.),
but Visual Studio 8.0 does !

public void abcMethod1()
{
string cspurl = @"http://xyz.aspx";
bool expected = true;
bool actual;
actual = @"http://xyz.aspx";
Assert.AreEqual(expected, actual, "");
}

Here actual Value means, what could i assign for actual variable as am getting mismatch error, as i assigned string value to bool variable.

Why are you testing a string value to a bool?

Don't you mean:

Assert.IsTrue(cspurl==actual, "Check string equality");

Re: Unit Testing of web page loading

sreecahitu5-Feb-07 8:35

5-Feb-07 8:35

even then am getting an error, "Operator '==' cannot be applied to operands of type 'bool' and 'string'", if i use the
Assert.IsTrue(cspurl==actual,"Check string equality");

you declared actual as a bool. Declare it as a string.

I probably don't understand this, but from when we can assign string values to bool (which is always true or false) data value type ?!

If you need compare two strings (use string's .Equals function) :

string ww1 = @"http://xyz.aspx";
string ww2 = @"http://xyz.aspx";

if (ww1.Equals(ww2))
{
// oh yes Smile | :)

}
