Many thanks for your reply. Let me be more specific to my problem.
- I am calling an 'Outlook 2000 New Message window' from VB.Net from.
- On Email ItemSend event I am updating the database by using a VBA macro
and closing Message window.
- When I get focus back to my VB.Net application, I want to refresh my current form with recently updated data.
I am using the following code to create a new mail.
Public Sub NewEmail(ByVal txtEmail As String, ByVal intContId As Long)
Dim objOutlook As Outlook.Application
Dim objNamespace As Outlook.NameSpace
Dim objMAPIFolder As Outlook.MAPIFolder
Dim objItem As Outlook.MailItem
Dim objProp As Outlook.UserProperty
objOutlook = New Outlook.Application()
objNamespace = objOutlook.GetNamespace(Type:="MAPI")
Try
'creating a process but it's not working
Dim Proc As New Process
Dim ProcInfo As New ProcessStartInfo
ProcInfo.CreateNoWindow = True
ProcInfo.FileName = ""
ProcInfo.UseShellExecute = False
Proc.StartInfo = ProcInfo
Proc.EnableRaisingEvents = True
AddHandler Proc.Exited, AddressOf ProcessExited
Proc.Start()
objMAPIFolder = objNamespace.GetDefaultFolder & _
(Outlook.OlDefaultFolders.olFolderInbox)
objItem = objOutlook.CreateItem(Outlook.OlItemType.olMailItem)
objItem.To = txtEmail
objProp = objItem.UserProperties.Add("ContactId", & _
Outlook.OlUserPropertyType.olNumber, False, False)
objProp.Value = intContId
objItem.Display()
objOutlook = Nothing
objNamespace = Nothing
objMAPIFolder = Nothing
objItem = Nothing
objProp = Nothing
Catch ex As Exception
msgbox err.message
End Try
End Sub
I would appreciate if you kindly guide me how to include a process object in this function. If you think there is a better way to solve this problem, kindly let me know.
Thanks again

Does any one know what is the fastest method of fetching data from database servers?
DataAdapter.Fill()?
DataTable.Load()?
DataReader?
|
|
|
|

DataReader is the quickest, but it has limited use. It gives you a read-only, forward-only cursor on the recordset that is returned.
DataAdapter (and DataTable) is the most flexible of the built-in controls, but is also slower. It gives you a completely navigable and editable copy of the recordset returned from the database.

The problem I am having is I need to enter values in a text box on a form
and transfer them to an Excel sheet. I need to be able to input up to 25
"scores" For example I submit 77 then click submit it runs the following code
For i = 1 To 25
'count = count + 1
'score = txtscore.Text
'Sheet5.Cells(i, "a").Value = score
'Next i
The problem is it enters score for all values A1:A25 I need the score to be entered in A1 then input another number into txtscore which is my text box. Then after I click the submit button I need that value to be placed in A2 and so on and so forth. Any suggestions?
Thanks

I don't know VBA, but
J-c-K wrote: 'Sheet5.Cells(i, "a").Value = score
it seems clear to me that when i is 1, it will go into A1, when it's 2, it will go in to A2, etc.

Thanks. It does go into A2 and so. However, I need the value in the text box to go into A1. Then I need the value/variable cleared then once another value is entered in the text box I want that value in A2 then cleared then A3 etc.
Private Sub CommandButton1_Click()
'txtscore.Text = ""
For i = 1 To 25
' hours = Cells(i, "b").Value
' rate = Cells(i, "c").Value
count = count + 1
score = txtscore.Text
Sheet5.Cells(i, "a").Value = score
txtcount = Sheet5.Range("B2")
txtmean = Sheet5.Range("B3")
txtstand = Sheet5.Range("B4")
Next i
End Sub

You're not going to use any kind of For/Next loop at all in this. You simply keep track of the row you're in in a simple integer variable. Every time you click Submit, or whatever you're calling your button, you put the textbox values in the cells, then increment the variable to point it at the next row. Check the variable to see if it's gone too far and adjust as you see fit. Then, you do nothing... The whole process starts over again on the next button click.

I have a question:
How can I create a search textbox that would find a certain person in my phonebook. I have created an acces database with a table phonebook. I imported it into my project and then created a form on which I dragged this textboxes which are connected to different fields ( firstname, lastname, adress, number, etc. ) via lets say phonebookBindingSource. I am describing this so in case you write a code, you could write it specificaly for my case. Any comments are very welcome othervwise it's like useless
help tutorials which are made for those who already know all that not for those who want to learn. Anyway I have tried quite a lot including building queries in access and then using that in VB and it doesn't work.
I should write the lastname in a textbox and then clik search button. So I suppose I shuld writte in a Button1_Click Subroutine what?...
But the primary key is on ID not on Lastname or name. There can be different persons with the same lastname so with each click it goes to the next and when at the end of table the procedure should go round again. The easiest way and comments pretty please.

I wanted to add that the name of the imported database is phonebook.mdb. I found some examples on the internet and they don't work.
as I have read I think I should make a database object and recordset. can I do this with a query like I put some kind of a statement in the criteria box which means whatever is written in the box of this querie field it filters out the records with matched lastnames...

I'm afraid they almost certainly do. You should take one example and work with it until you can make it work locally, asking specific help questions there or here.

select top 1 * from tblPhoneBook where firstlame like '%firstName%' and lastname like '%lastname'
is something like the query that would do this, and yes, you do need to write a button click handler for your button to do something.
dragging buttons, and binding sources, is not programming. It sounds to me like you need to buy a good book and work through it, you need a foundation to be able to make the most of online resources.

Somebody got up on the wrong leg I suppose...
I want to implement a simple search engine for a simple phonebook, not creating Windows 3000. I tried some examples and so I got it to work but this is a bit heavier. I didn't find any suitible example I turned here. I didn't find anything promissing so I ...
And I do thing VB is abaut dragging controls to forms and adding functions to it otherwise you would still use assembler language.

It people like you who give VB a bad name. Christian is correct. Programming, in ANY language, is NOT just dragging controls onto a form and sprinkling it with code.
You MUST understand how and why the controls work and precisely what they are used for. In that understanding you will also learn the limitations or those controls and also learn who to expand on their capabilities.
After reading your original post, you have an interface design problem. Normally, lists like that are shown AS LISTS, not each record individually. It can be done though. But your interface choice makes it more difficult to do and can NOT be done by just dragging and dropping controls. You'll have to write quite a bit of code and completely understand how data binding works and how to set it up manually in your own code, because that's exactly how it needs to be done.
Can I supply a code sample and write you're stuff for you? Nope. There's too much to write in a forum post and you wouldn't learn anything in the process.
Basically, your form has to be able to switch between two datatables. The first one you already have. The second one, you have to make entirely in code, this is the result of your "filter search", and setup the control bindings to point to it - manually.
When you click another button to clear the search results, you reset the control bindings to your original datatable.

That's why I suggest you read a book. If you wanted to do something complex, I'd have said to forget it.

As Dave said, this is why VB has a bad name. You can create something that does something without ever writing code, but
a - that's not programming and
b - you'll hit the limits of that approach pretty fast.
I wasn't trying to be rude, I was trying to give good advise. I stand by it, if you want to be a programmer, you have to write code. If you find code on the web, you need to do some research to understand what it is you're adding, otherwise you're at the mercy of whatever google throws at you, and you'll never make the bits you paste in talk to each other nicely. Either way, you should always read a book as the first step to learning a new language, then you can have a basis from which to learn via code snippets and forums.

Niether I wanted to be rude. Never said I was a top class programer otherwise I wouldnt be here. Never had any complaints abaut VB or other programs nor wanted to upset you especially if you participated in development in this kind of software. I read for me interested sections in VB for dummies, VB from novice to pro, MS VB step by step and some web pages. I know I have a lack in object oriented programing cause I am now learning for abaut a week and although I don't know all the modules, proceedures, events, ... I shouldn't be able to writte some programs which could be very helpfull. I am not trying to sell them or anything. Don't want to molest you too. Just seeking for little help. Examples are mostly without proper comments. Like a reciepe with ingredients and no how to sentences.
Examples which are given are to easy like read text from textbox1 and write it to another one, some calculators, etc. I haven't had the opportunity to se the code behind move next button in databasebinding navigator or save or add, with some minimum explanation. Thats how you learn programming. By good examples with comments. I was very stunned when practically no good examples of a search engine was not found on the web, because this is one of the most common objects you use in a database. I have seen some good examples abaut graphics and creating a simple paintbrush or a simple web browser, so. Don't want to bore you but I admire your work but you should be a little more tolerant and plastic or open minded. Sorry for spending your time, but I thought you should abaut my situation, cause...

This is the code I found...
Public Class Form2
Dim dbMyDB As Database
Dim rsMyRS As RecordSet
' this part is supposed to create a recordset of phonebook table in phonebook.mdb
Private Sub Form_Load()
Set dbMyDB = OpenDatabase("Phonebook.mdb")
Set rsMyRS = dbMyDB.OpenRecordSet("phonebook", dbOpenDynaset)
If Not rsMyRS.EOF Then rsMyRS.MoveFirst
Do While Not rsMyRS.EOF
lstRecords.AddItem rsMyRS!Name
lstRecords.ItemData(lstRecords.NewIndex) = rsMyRS!ID
rsMyRS.MoveNext
Loop
End Sub
Private Sub Button1_Click()
rsMyRS.FindFirst "ID=" & Str(lstRecords.ItemData(lstRecords.ListIndex))
txtPhone.Text = rsMyRS!Phone
End Sub
End Class

Again, 'finding' code is not the same as understanding how to use it.
This looks like a disaster to me. I would throw this in the bin and use the database to do your searching, that's what it's for.

This is what I found on the web. I want it to make it work. It describes a bit of it's funcionality but very scarce. Never give up I say. I hopped you could correct it a bit and added some comments. Whell in the datanavigationbar if I am not mistaken there is a textbox that automatically displays the index position of the currenty displayed record. If I write lets say 10 in it and press enter then it automaticaly jumps to record number ten. How can I see the code behind it, I could certainly use the code and learn from it. If I double click on it then I get in the form class another subroutine with click event. the same I would like to se for move next button and save and so.
Don't get upset please cause I don't want anyone to get a stroke or diarea or something like that...
Greetings.

Well, I'm saying that you need instead to do things the right way, write some SQL that requests the data you want from the DB. I gave you the SQL in my first reply, or at least an approximation of what it should be.
The way I would write a method that views one record at a time would depend on the data set. If it was not huge, I'd read it all from the DB and just step over it with my buttons. I'd still not look for records in memory, I'd still write SQL and let the DB do that for me. I'd use my existing functionality then to step over the matches, as my collection would only contain records that match.
http://www.developerfusion.co.uk/forums/p/28135/104686/#104686[^] has a reply showing how to do a dynamic search in Access with VB.NET. It was the first hit when I googled 'vb.net search access database', it looks like a good place to start.

OK - so the problem is solved, or you found another code snippet that doesn't work and you're asking how to make it work ?

I'm getting an unusual error message may be I'm wrong here is the error can anyone please tell me how to resolve it:
The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF
And here is the code that raised this error:
Dim wr As HttpWebRequest
Dim wrs As HttpWebResponse
wr = HttpWebRequest.Create("http://www.google.com/")
wr.Method = "HEAD"
wrs = wr.GetResponse()
MsgBox(wrs.Headers.ToString())

According to the error message, your code didn't generate the error, Google's web server did. HttpWebRequest is correct is saying so because it's following the parsing rules for HTTP 1.1 headers closer to the RFC specification than Google web server did putting the headers together. It's not Google's fault really, but the people who wrote the web server. There's an old recommendation in the RTF for HTTP 1.0 that said something like:
"the line terminator for message-header fields is the sequence CRLF. However, we recommend that applications, when parsing such headers, recognize a single LF as a line terminator and ignore the leading CR."
The headers comming back from the server ARE, according to which section of the RFC for HTTP you're reading, malformed.
You can turn on an option in your applications app.config file to force HttpWebRequest to relax it's parsing rules and suddenly start working with a large collection of web servers that were never "fixed" because "they worked before!"
<configuration>
<system.net>
<settings>
<httpWebRequest useUnsafeHeaderParsing="true" />
</settings>
</system.net>
</configuration>

I've done some research before posting this question on Code Project and found the same solution in Msdn forum and did the same thing but it didn't display the headers received from the server but now it did I think there was something wrong with my network connection. As far as solution goes don't you think that Microsoft should make this class more fault tolerant so that it can handle such situations.
