Use DateTime.MinValue.
public static readonly DateTime MinValue;<br />

Remarks<br />
The value of this constant is equivalent to 00:00:00.0000000, January 1, 0001.

I got Microsoft Visual Studio 2005 Beta 2 and I developed a program. I asced some people to run it and they said it didn't.
How do I make it work on other computers?

They must have the same version of the .NET Framework installed as the one you used to develop the application. Since you used VS 2005, they need to have the .NET Framework 2.0 Beta installed.
But, this is not as simple as it may seem. You can't just download the .NET Framework 2.0 redistributable package and install it anywhere. It's still a Beta and not authorized for release.
See this[^] page for more information.

In all practicality, though, I can't imagine anyone will be upset if he makes his users install the 2.0 beta, assuming this is "see what I did" kind of thing as he made it sound.

Hello,
I have a dataset, and I want to go through the dataset, and select particular rows. Is there a way of defining a DataRow array, to which I can attach the picked rows.
I tried to use:
DataRow[] myRows = null;
and then putting the selected rows there, but to no avail.
Any ideas?
Thank you.

I created a smart document that creates a list of students in word. This information comes from a custom API exposed by a .NET application I made.
All seems ok, except: I can't get the security right for the document, it keeps telling me my security settings are wrong and I don't have the full trust policy on my assembly.
I checked everything:
- I have a zone Office_Projects
- I have a specific zone for my <docname>_bin with execution rights
- I have a specific zone for my <docname>.dll inside the bin folder that has fulltrust.
Still it doesn't work. Anyone have had this problem before and can tell me more about this issue?

Hi
I want to create a page where someone can view if someone has been seen within a week or not with 2 buttons on the page, 1 to click which will display records of people who were which will show results in a datagrid and another button to show which was not and to show in a datagrid.
The way the system works now is someone fills out an initial form which populates the data in a table below and the date of submission is recorded:
Initial Referral table
RefID int 4 0
Base varchar 150 0
CustNumber int 4
ReasonForAppointment varchar 50
TimeSpent varchar 50
Contact varchar 50 0
CustomerType varchar 50
Comments varchar 2000
DateSubmitted datetime 8
Then someone else will need to follow up the referral from another form and the following is added and date of submission recorded:
Follow up table
FollowUpID int 4
RefID int 4 0
AdditionalInfo varchar 2000
Point1 bit 1
Point2 varchar 2000
DateToBeCompleted datetime 8
ClientSeen bit 1
DateSubmitted datetime 8
I have the form pages all done, it is just this page i am having a problem with so it can calculate if the dates are longer or shorter than the 2 dates from the two tables and fill the datagrid with the right results.
Any hints or points in the right direction will be appreciated.
Cheers

How do I convert an array of objects to an array of bytes?
I don't know how to do it the old way like in C, get the address of and the size of the object and then save it to a file...

If you're just wanting to serialize the array, the following should work (generically, for any binary serializable type):
using System;
using System.Runtime.Serialization.Formatters.Binary;
namespace SomeStuff
{
class Class1
{
[STAThread]
static void Main(string[] args)
{
string[] foo = new string[3]{"a", "b", "c"};
byte[] bytes = BinaryConverter.SerializeThis(foo);
string[] newFoo = (string[])BinaryConverter.DeserializeThat(bytes);
foreach(string s in newFoo)
Console.WriteLine(s);
Console.ReadLine();
}
}
class BinaryConverter
{
private BinaryConverter(){}
public static object DeserializeThat(byte[] bytes)
{
object graph = null;
if (bytes != null && bytes.Length > 0)
{
BinaryFormatter formatter = new BinaryFormatter();
MemoryStream stream = new MemoryStream(bytes);
graph = formatter.Deserialize(stream);
stream.Close();
}
return graph;
}
public static byte[] SerializeThis(object graph)
{
byte[] bytes = null;
if (graph != null)
{
BinaryFormatter formatter = new BinaryFormatter();
MemoryStream stream = new MemoryStream();
formatter.Serialize(stream, graph);
bytes = stream.GetBuffer();
stream.Close();
}
return bytes;
}
}
}

I don't know what to serilize an array is but you forget to include
using System.IO;
And I got some errors wich I fixed with making the class I used [Serializable]
I really just want to save the data to a file...
And after a little fixing it worked. Thanks

I got an error. If I saved an array of 8 objects it loads 9 and the last one is null.
That's bad.

That's not a lot to go on. I have no idea what your source code looks like. If you'd like to include it (code that builds the array, serializes it and deserializes it, along with the type you're trying to serialize in the array), I can have a look.

It's huge... I'll only post some parts of it...
The code for each class is huge, I hope the structure is enough
Item.cs:
namespace NiklasUlvinge.ChipsEater
{
[Serializable]
abstract class Item
[Serializable]
class Void : Item
[Serializable]
class Cord : Item
[Serializable]
class Ground : Item
[Serializable]
class theGround : Item
...
}
form1.cs:
namespace NiklasUlvinge.ChipsEater
{
public partial class Form1 : Form
{
#region FileHandling
private void OpenFile_Click(object sender, EventArgs e)
{
openFileDialog1.ShowDialog(this);
FileStream fs = new FileStream(openFileDialog1.FileName, FileMode.Open, FileAccess.Read, FileShare.None);
byte[] data = new byte[fs.Length];
fs.Read(data, 0, (int)fs.Length);
items = (Item[])BinaryConverter.DeserializeThat(data);
fs.Flush();
fs.Close();
SetParent();
PB.Refresh();
}
private void SaveFile_Click(object sender, EventArgs e)
{
saveFileDialog1.ShowDialog(this);
FileStream fs = new FileStream(saveFileDialog1.FileName, FileMode.Create, FileAccess.Write, FileShare.None);
byte[] data = BinaryConverter.SerializeThis(items);
fs.Write(data, 0, data.Length);
fs.Flush();
fs.Close();
}
#endregion
private void toolStripButtonClear_Click(object sender, EventArgs e)
{
items = new Item[1] { new theGround(items) };
SetParent();
PB.Refresh();
}
private void addItem(Item item)
{
Item[] titem = new Item[items.Length + 1];
for (int i = 0; i < items.Length; i++)
{
titem[i] = items[i];
}
titem[items.Length] = item;
items = titem;
SetParent();
if (item.x - PB.Width > hScrollBar1.Maximum)
hScrollBar1.Maximum = item.x - PB.Width;
if (item.y - PB.Height > vScrollBar1.Maximum)
vScrollBar1.Maximum = item.y - PB.Height;
}
private Item getItem(int x, int y)
{
for (int i = 0; i < items.Length; i++)
{
if (Math.Abs(items[i].x - x) < items[i].Width)
if (Math.Abs(items[i].y - y) < items[i].Height)
if (items[i].GetType() != new Cord(-50, -50, items).GetType())
return items[i];
}
return null;
}
public void SetParent()
{
for (int i = 0; i < items.Length; i++)
{
items[i].parent = items;
}
}
}
}
Hope this was enough, I only included the most neccesary parts...

I can't really tell for sure, but my guess would be that in your addItem method you're creating an array where the last item (set to the value of the 'item' parameter) is null.
Have you inserted a breakpoint in your code just prior to serialization (in SaveFile_Click ) to inspect your array and ensure that the length is what you expect it to be, and that all the elements in the array are non-null?
If you want, just email the source to me.

I couldn't find any error in the any of the file funcs...
I then made some UI improvements and now the error is gone!
Thank you for your help.
It's a circuit simulator, but it's not that good yet. It got some foults... It's the Kirchkorvs (or whatever he's called, I can't remember) rule that's not working as it should.

I wasn't really aiming at providing you with a completed application - just some sample code.
If you don't know what serialization is, I would suggest reading about it before using it - it's in the MSDN documentation under "Serialization".
Glad to have helped.

Hi
I'me working on a tapi project with tapi3.dll. I successfully created calls with ITAddress etc. Now I tried to call the method TranslateAddress from the class ITAddressTranslation, which is an abstract class. Unfortunately without success.
Now the question: Does anybody know how I can use this method? How do I have to instantiate the class ITAddressTranslation in order to get this method?
Thanks Fredy

Hi,
I want to filter the rows of the DataTable using the DataTables's Select() method.
I have a DataTime column in the DataTable. My Search Criteria should check that
DateTime Column's Hour value with the present System Time's Hour value
and
DateTime Column's Minute value with the present System Time's Minute value.
What functions/methods can i specify to extract the Hour, Minute from the DateTime column of the DataTable?
The following is the code:
string lstr = string.Empty;
lstr = "datename(hh,getdate())= datename(hh,schedule_time) and datename(mi,getdate())= datename(mi,schedule_time)";
DataRow[] dr = mds.Tables[0].Select(lstr);
Thanks in advance.

hey all,
am getting image using SHGetFileInfo for form Image, but when i put it onto a toolbarbutton i get black where it should be transparent.
i tried to convert to bitmap before putting icon into the imagelist but still no good.
any ideas pls?
<br />
private void CreateNewMDIChild(string path)<br />
{<br />
EditorPane pane = new EditorPane(path);<br />
pane.MdiParent = this;<br />
pane.Show();<br />
<br />
this.documentImageList.Images.Add(pane.Icon);<br />
<br />
ToolBarButton button = new ToolBarButton(pane.FileName);<br />
button.ToolTipText = pane.Path; <br />
button.ImageIndex = MdiChildren.Length - 1;<br />
this.mdiChildrenToolbar.Buttons.Add(button);<br />
<br />
UpdateButtonPushState(button);<br />
}<br />
kind regards,
g00fy

Hi,
Check for the size of the Image/Icon and the Image Size selected for the ImageList control. Both the size should match inorder to display the icon properly
Best Regards,
|
|
|
|
|
yes they are same => 16, 16, transparentColor = transparent, ColorDepth => Depth8Bit
one thing i have noticed debugging is that the depth of the icon of the form, is 0 which is not same as imagelist.
regards,
g00fy

Hi!
Could be the rather well-known "32bpp images in an ImageList lose transparency" bug.
You'll find a lot of stuff/suggestions/discussions when you google for "imagelist transparency bug".
Regards,
mav
