Hello!
I would like to import conactinformation to Microsoft Outlook C#. I know how to do this if you want the information to be put into your regular contactlist in Microsoft Outlook. But I can't get it to be a part of "Public Folders -> All Public Folders". Here is my code:
<br />
public void exportContactToOutlook(Person contact)<br />
{<br />
Outlook.Application objOutlook = new Outlook.ApplicationClass();<br />
NameSpace outlookNS = objOutlook.GetNamespace("MAPI");<br />
MAPIFolder contactFolder = outlookNS.GetDefaultFolder(OlDefaultFolders.olPublicFoldersAllPublicFolders);<br />
<br />
<br />
Outlook.ContactItem objContact = (Outlook.ContactItem)objOutlook.CreateItem(Outlook.OlItemType.olContactItem); <br />
objContact.CompanyName = contact.CompanyName;<br />
objContact.Save();<br />
}<br />
This will only save it to the regular contactlist. I know that this code shouldn't work but what is the missing link? Any ideas?

How can be a transparent panel control can be created. As I tried in many ways but it is applicable to window but not to the required control (panel), as well as I also have observed that Transparency will be applicable to windows forms but not to user control. Is it so, if yes why.

Try making a bitmap that is all one colour and setting it as the background image for your panel.
Then add the following code to the form_Load event
Bitmap bitmap = (Bitmap)pnlBackground.BackgroundImage;
bitmap.MakeTransparent(bitmap.GetPixel(1, 1));
TransparencyKey = BackColor;
You may also need to start the form minimized and then do WindowState = FormWindowState.Normal; I don't know why but sometimes this is the case.
Cheers

Hi,
How to start and stop windows services using c# asp.net.
Thanks

You can use the System.ServiceProcess.ServiceController class, from the System.ServiceProcess.dll assembly.
Bear in mind that you generally need administrative privileges to stop or start a service, which your ASP.NET code will not normally have. You'll typically have to change the user that the code runs under. On Windows 2000 or Windows XP, you configure this with the <processModel> element in the Machine.config file, and it affects all ASP.NET applications on the server; on Windows Server 2003 you configure it through the Internet Information Services administration console, all applications in the same application pool share the same worker process.
Stability. What an interesting concept. -- Chris Maunder

I am reading a file into a listBox as follows:
***********************************
StreamReader SR;
FileStream FS = File.Open("c:\\wsIder\\info.ini", FileMode.Open, FileAccess.Read);
SR = new StreamReader(FS);
string line;
while((line = SR.ReadLine()) != null)
{
viewS.Items.Add(line);
}
SR.Close();
******************************
the file contains section separated with bracket like this
[SEC1]
...some text
[SEC2]
...some text
etc
When I display the file in the listbox, I would like to use colored text for the sections. [SEC1]=red, {sec2]=green..etc
Any idea how to do this?
|
|

|

With the standard listbox control, you cannot do that. You need a owner drawn listbox. See this article: this is probably what you need:
http://www.codeproject.com/cs/combobox/colorlistbox.asp[^]
Once you have implemented the listbox as described in the article, you just have to do some parsing of the text you read from the file, like if the line starts with a '[' then change that item's color to red... etc etc

name(parent) should show up on the root node of the tree. and age and
salary(child) should show up under the root node.
as I am new to infragistics , I am learning. Please help me with
coding..and please explain me ...

What is infragistics, a class library ? You need to ask them.

I have 2 classes and I want when the second class raises an event, the first class can catch and do something.
I have heard about using delegate to do this, but I dont know how to do?

I am having an issue with ConfigurationSettings.AppSettings in a multi-threaded winforms application. I have an error thrown by the .net framework Config class when both the main thread and worker thread access the AppSettings namevalue collection. Is this a threadsafe issue? I have tried using lock for the AppSettings collection, but this throws the same error. Below is the code to reproduce the error:
private void Form1_Load(object sender, System.EventArgs e)
{
MethodInvoker myInvoker = new MethodInvoker(WorkerThreadFunction);
myInvoker.BeginInvoke(new AsyncCallback(WorkerThreadAsyncCallBack), myInvoker);
NameValueCollection nvc = ConfigurationSettings.AppSettings;
}
private void WorkerThreadFunction()
{
string settingVal = ConfigurationSettings.AppSettings["Setting1"];
}
The following error results:
"Object reference not set to an instance of an object"
Stack Trace:
at System.Configuration.ConfigurationRecord.Evaluate(String configKey)
at System.Configuration.ConfigurationRecord.ResolveConfig(String configKey)
at System.Configuration.ConfigurationRecord.GetConfig(String configKey)
at System.Configuration.DefaultConfigurationSystem.System.Configuration.IConfigurationSystem.GetConfig(String configKey)
at System.Configuration.ConfigurationSettings.GetConfig(String sectionName)
at System.Configuration.ConfigurationSettings.get_AppSettings()
Can anyone shed some light on this issue?
Thanks in advance...

I want to define a Row as an object:
if my database is:
[Text][Text][OLE OBJECT]
i want to create an row object in my c#application with that structure.
Insert value inside the put in some way in the original Database.
Is it possible with ADO.NET?
|
|
|
|

You could write a bunch of code to do that, but ADO.NET does not work that way by itself. It's designed to be disconnected, so you'd need to write all the code to keep connecting and updating values when you set them.

so are you telling me is it not possible?
Another thing:
If i've to add some Field into a table with the INSERT query, but i have to leave empty someother what is the correct query:
INSER into table mytab ([Name], [Surname], [EYESCOLOR], [IMAGE]) Value ('Mike', 'Tyson', 'Null', 'Null')
or
INSER into table mytab ([Name], [Surname], [EYESCOLOR], [IMAGE]) Value ('Mike', 'Tyson', '', Null)
INSER into table mytab ([Name], [Surname], [EYESCOLOR], [IMAGE]) Value ('Mike', 'Tyson', 'NULL', NULL)
????

Not without writing the code, no.
Neither. It's DBNull.Value, I believe.

Standard question #1:
What do you mean by "not working"?
Standard question #2:
What error message do you get?

Like the error message says...
tempStream = new MemoryStream(
imageBytes, oleOffset, imageBytes.Length - oleOffset);
I'd say this is wrong. Certainly somewhere you're using values that don't index into the data as they should.

there are columns called FrontImageOffset, FrontImageSize that tells me where an image's byte stream ends and a new image begins
so, I am using a sql command like below to figure out what I am supposed to looking for..
sql = "select FrontImageOffset, FrontImageSize from CDData where TransactionId=" + TransactionId;
using (SqlCommand cmd = new SqlCommand(sql, cn))

Well, it's obvious that somewhere you are trying to pass an array index that is outside the bounds of the array. Maybe it's not this line, I didn't look through your code closely.
