hi
thanks
but Configuration does not exist in Configuration namespace (but ConfigurationSettings exist)
can u other way to suggest me ??

I'm sorry. I've provided solution for .NET 2.0. You apparently have .NET 1.1. Am I right? As I know only config reading is possible for .NET 1.0 but I can be mistaken. If I'm right you can use xml to work with configuration. Have a luck.

Hi,
I created a dataset with the designer of the VS 05 and added a query into it.
I found out that this query takes some time on slow computers and I want to make the CommandTimeout larger.
I checked the properties of the query and I can change several parameters like the CommandText and the CommandType, but the CommandTimeout is missing.
I don't want to change the CommandTimeout within the code generated by the designer, because it will be deleted each time I update the scheme.
So how can I do this without changing the designer's code?
I thought about using partial class, but I don't have an idea of how to do this.

Hi, I am creating forms that use a menubar (file-save,print, etc.). In visual studios 2003 I could keep the menubar from scrolling by selecting true in the locked property field. I 2005 I even though I lock it for some reason it still scrolls with the form.
Do you know a way to keep the menubar from scrolling with the form in vs 2005
Thanks

As of how to accomplish that have you ever tried Google?
Failing that try ![Badger | [badger,badger,badger,badger...]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/badger.gif) .

|
|
Yes I tried and i always get the VB examples and not the C#

What exactly is your problem? The whole concept or a particular bug?

Change the SelectionMode to one of the following:
SelectionMode.MultiExtended;<br />
SelectionMode.MultiSimple;
listBox1.SelectionMode = SelectionMode.MultiExtended;
listBox2.SelectionMode = SelectionMode.MultiExtended;

Hi,
Does anyone know of a way to detect a text file's encoding (ANSI, UTF8, UTF7)?
So that I can read the text file in a StreamReader with the right Encoding enabled.
thanks
|
|
|
|
|
It should automagically do it for you, just use a constructor which doesn't accept an Encoding value.

hi,
im working in a trial version of vs2005
and if i am useing databases, link them with a datagrid using the wizard, it doesn't generate a delete statment, therefor i always get an error when i want to delete and update afterwords.
this is the error:
update requires a valid delete command when passed datarow collection with deleted rows
could this be because of the trial??
plllzzzzz help meeeee

No. It's more likely that you'll need to add a valid delete statement.
Also, a trial of Visual Studio? Do you mean the Visual Studio Express version? If so, that's not a trial.

can somebody help me?
how can i check a checkbox in a checkbox cell?
my currenty code is like that:
<br />
colValueCheckBox.TrueValue = "1";<br />
<br />
DataGridViewCheckBoxCell cellValue = colValueCheckBox.CellTemplate.Clone() as DataGridViewCheckBoxCell;<br />
<br />
cellValue.Value = "1";<br />
gridRow.Cells.Add(cellValue);<br />
grid.Rows.Add(gridRow);<br />
but it doesent check the box in that cell
(i need some code to check this box! - can be different to that)

I'm not too familiar with the DataGridView, but have you tried doing something like cellValue.Value = true; ?
|
|
|
|
|
ok thats what i already tried to check this box, too:
<br />
cellValue.Value = true;<br />
cellValue.Value = colValueCheckBox.TrueValue;<br />
i also tried cellValue.Value = true; without setting any TrueValue or FalseValue.
i also tried to test it with ThreeState = true;.
|
|
|
|
|
Ok, i found the answer, i added the checkboxcell to a invisible column, and i didn't think about that as i add the cell of a row.

Hi all
Im trying to load a dll programmed in C, but I'm not sure exactly how to go about it. I read the following article:
http://msdn.microsoft.com/msdnmag/issues/02/08/CQA/
My problem is that Im not quite sure how to handle the return types. In the header file I several type definitions. Below you see some of the type definitions and two of the methods availeble in the DLL.
<br />
<br />
#if defined (OMA_LIB_INTERNAL)<br />
# define OMA_DLLEXPORT DLLEXPORT<br />
<br />
#else<br />
# define OMA_DLLEXPORT DLLIMPORT<br />
#endif<br />
<br />
<br />
#define OmaC_Ov_Default_Report_Name ""<br />
#define OmaC_Ov_Global_Object_Path ""<br />
#define OmaC_Ov_Unspec_Str "unspecified"<br />
<br />
<br />
typedef struct OmaT_Ov_Writer OmaT_Ov_Writer;<br />
typedef struct OmaT_Ov_Reader OmaT_Ov_Reader;<br />
typedef struct OmaT_Ov_Vector OmaT_Ov_Vector;<br />
typedef struct OmaT_Ov_Reader_Iterator OmaT_Ov_Reader_Iterator;<br />
......<br />
<br />
<br />
<br />
<br />
OMA_DLLEXPORT OmaT_Ov_Reader *<br />
Oma_Ov_Reader_Open (const char *ov_file_name);<br />
<br />
OMA_DLLEXPORT OmaT_Ov_Vector *<br />
Oma_Ov_Reader_Vector_Get (OmaT_Ov_Reader *ov_reader_ptr,<br />
const char *report_name, const char *obj_path,<br />
const char *group_and_stat_name);<br />
......
My question is: How I use import this DLL?
At the moment I have an idea that it should be something like the following, but I have no clue how to define the structs which Im using and which gets returned. See below:
public class OMAInterface<br />
{ <br />
<br />
[StructLayout(LayoutKind.Sequential)]<br />
public struct OmaT_Ov_Vector<br />
{<br />
}<br />
<br />
[StructLayout(LayoutKind.Sequential)]<br />
public struct OmaT_Ov_Reader<br />
{<br />
}<br />
<br />
[DllImport("opoma_opt.dll")]<br />
public static extern OmaT_Ov_Reader* Oma_Ov_Reader_Open (const char *ov_file_name);<br />
{}<br />
<br />
[DllImport("opoma_opt.dll")]<br />
public static extern OmaT_Ov_Vector* Oma_Ov_Reader_Vector_Get (OmaT_Ov_Reader *ov_reader_ptr, const char *report_name, const char *obj_path, const char *group_and_stat_name);<br />
{}<br />
}
Any help is much appreciated

Hi,
I have a small problem. I want to create 2 properties to one of my classes. All I want is to make easier for the users of my class to get some data out of my class. I want when a user writes
Test[i] to get some data and when the user writes
Test[i][j] to get another type of response.
I need a little help with the second type of property:
public class Test
{
public object this[int index]
{
get
{
}
}
}
This one works. My question is how to write the second one?
Thanks in advance
Do your best to be the best
