There are no wizard controls built into the System.Windows.Forms UI toolkit, however, there are several free ones, such as this one[^], available for download.

Can anyone help me to add an image in crystal report? I write in C#. In my access database, I store the path of the image , not the real image. The real image is in another directory.
Thank you very much.

My application uses a 3rd party component to do serial comms. As part of the initialisation routines of this component it generates an exception.
If I am debugging then this exception takes ages to be caught. The release version takes no time at all.
Why does the first exception take so long, and is there anything I can do about it?
|
|
|
|
|
I would run this by the Visual Studio team in the MSDN forums. Most likely it is due to some COM-related issue, possibly attempting to be caught by a managed debugging assistant. Have you tried turning off MDAs temporarily to see if that affects it at all?

Hi, it's me again 
I have function in an unmanaged DLL declared this way:
unsigned int CWB_ENTRY someFunc();
The CWB_ENTRY is expanded as _System (in a #define preprocessor directive). Anybody knows what calling convention is this?
Thank you.

I am hoping to write a c# program to log which applications have been started and which ones become active/in focus. I assume I will need some api of somesort or is there something in the .net framework I can use.
Please help
thanks in advance

Well, you could periodically poll the System.Diagnostics.Process.GetCurrentProcess() list to see which apps are started. As far determining the active window, there is nothing in the .NET framework to return that information. You'll need to P/Invoke into a Win32 API to obtain this information.

You basically cannot do memory management in C#, so those methods don't have any equivalent in .NET.
What are you trying to achieve?

You can copy a block of bytes to another byte array using the System.Buffer class[^].
Of course, you can still use pointers and allocate blocks of memory in C#. But typically this is not required, and generally frowned on since it's usually a better practice to let the CLR manage the memory allocations and deallocations for you.

Anybody has a link to an article where I can find all the possible mappings between C# and C types in order to correctly declare them using DllImportAttribute?
I am looking for types like pointer types, often used to return data to the caller.
Thanks all.

Hi to all,
I am facing really strange problem. Could you please help me out from that?
LET me describe my requirement.
-------------------------------------------------------------------------------
We have list of "projects" which has some role like - PM, PL, TL, Developer, Tester etc. and absence of any of the person for the particular role, i have to assign other person, which has same role, in the project.
ie database is like this,
PM PL DEV TESTER
Project1 pml pl1 dev1,dev2 t1
Project2 pm9 pl10 dev18,dve20 t3,t10 etc..
PM = pm1,pm5,pm10,pm12 ect..
PL = pl1,pl11,pl10 etc...
so after setting back up of all projects, i have "save" button which save all the projects‘ back up in one table.
-------------------------------------------------------------------------
let's move on GUI...
I have one dropdownList - ddl which has roles (PM,PL,TL etc..)
and in datagrid i have 3 cols
1) Label - project name
2) TextBox - Person who is currently assign the role listed in dropdownList - ddl
3) ListBox - All the person who has same role in database listed in dropdownList - ddl
ie if i select TL in dropdownList, Datagrid shows,
1) all projects 2) person assign TL for the project. 3) all the person who are TL
I have a SAVE button which save all the projects backup at once.
------------------------------------------------------------------------------
To bind the Datagrid, i have use..
**************
asp:Label Runat=server id =name Text='%# DataBinder.Eval(Container,"DataItem.Name")%'
asp:TextBox text= '%# DataBinder.Eval(Container.DataItem,"Asigned Role") %'
Note - this two control bind by DataSet which returns “Project Name” and “Person Name”
***************
asp:ListBox Runat=server id ="ddl1" DataSource='%# getallData1() %' DataTextField="AllRoles" DataValueField="AllRoles" SelectionMode=Multiple
this is i dynamically bind with function "getallData1" which retunrs DataTable with one column - All person who is TL.
---------------------------------------------------------------------------
On save button i wrote code like
***********************************
private void Button1_Click(object sender, System.EventArgs e)
{
ArrayList arr = new ArrayList();
foreach (DataGridItem dgi in DataGrid1.Items)
{
Label lb = (Label) (dgi.Cells[0].Controls[1]);
TextBox tb = (TextBox) (dgi.Cells[2].Controls[1]);
ListBox lb1 = (ListBox) (dgi.Cells[1].Controls[1]); arr.Add(lb.Text.ToString());
arr.Add(tb.Text);
for (int i=0;i < lb1.Items.Count;i++)
{
if (lb1.Items[i].Selected==true) arr.Add(lb1.SelectedItem.Text);
}
}
ListBox1.DataSource = arr;
ListBox1.DataBind();
}
-------------------------------------------------
Right now i want to list all items in LISTBOX1 which has FirstRow as Project NAme, SecondRow TL Name, ThirdRow Backup of TL / BackUp of TLs
---------------------------------------------------
So, main problem is that.. I can access Label – Project Name, TextBox – Person name. But I can’t access the selected Value of Listbox in DataGrid. It always gives me all items as deselected.
Can any one tell me how to get all the records which I selected in Listbox?
Thanks in advance.
Bye.

I think I understand your problem. To sum all of it up, you want to access the new selected value in the ListBox. I am using a GridView in this code sample but it should work about the same. Instead of using strings with "," you could add straight into your array. Tell me how it works
protected void btnRun_Click(object sender, EventArgs e)
{
int intRowCount = GridView1.Rows.Count - 1;
string strDDLVals = "";
string strLBVals = "";
for (int i = 0; i < intRowCount; i++)
{
strDDLVals += ((DropDownList)GridView1.Rows[i].FindControl ("ddl1")).SelectedValue + ",";
strLBVals += ((ListBox)GridView1.Rows[i].FindControl("ListBox1")).SelectedValue + ",";
}
strLBVals.TrimEnd(',');
strDDLVals.TrimEnd(',');
}

It's working.....

Then you should definitely train using the docs.
Since we have marvelous weather today in germany and I'm in a really good mood, here the code that should do what you want. Read the link I provided before and the docs of the involved classes to learn more.
XmlDocument doc = new XmlDocument();
doc.Load("file.xml");
public void WritingToXMLDoc(string elementString, string writeToXMLDoc)
{
XmlElement element = doc.CreateElement(elementString);
XmlText text = doc.CreateTextNode(writeToXMLDoc);
element.AppendChild(text);
doc.DocumentElement.AppendChild(element);
}
doc.Save("file.xml");
