Hi there. I think the declaration of ByVal arg2 as String is correct for working with LPCTSTR types. I wonder if declaring the return type as Boolean is where the problem is. Try declaring the return type as Long instead.
|
|

|

The return type in the DLL is Boolean. I tried declaring the return type as Long, but it doesn't seem to work.
I'm trying to set an If statement to ensure the function is working properly:
Dim errtcp As Long
errtcp = function_Name(txtip, txtport)
If errtcp = 0 then
isopen = true
else
msgbox "error"
exit sub
end if
The function always seems to open, errtcp = 0, even though in certain cases I know it should not work.
Do you have anymore ideas?

Hi there. So the function is being called successfully then, and seemingly returning 0 in all cases? Would you have the source code for the C function itself?
|
|
|
|
|
Here is the C code:
#if defined(_WIN32) || defined(WIN32) || defined(__WIN32__)
#define API__declspec(dllexport)
#else
#define API
#endif
API boolean function_name(LPCTSTR arg1,LPCTSTR arg2 );
I'm thinking the API has something to do with my problem.
Thanks for your help!!

Hi
I you must use __stdcall in the functions exported to VB:
(if I remember correctly) the usage is like this:
<br />
API __stdcal boolean function_name(LPCTSTR arg1,LPCTSTR arg2 );<br />
|
|
|
|
|
Sorry about that. Here is the code I am using. I already updated to _stdcall. I submitted the old version of the code by mistake.
#if defined(_WIN32) || defined(WIN32) || defined(__WIN32__)
#define API
#define CALL __stdcall
#else
#define API
#define CALL
#endif
API boolean CALL function_name( LPCTSTR arg1,LPCTSTR arg2);
The function is recognized in VB fine, I just can't seem to pass the arguments properly. Any Ideas??

I have a problem.I am trying to post data from vb.net file to php file.I have achieved this issue in asp file,but I can't realize on php file.Here is my pseudocode for asp file:
Request = WebRequest.Create("http://" & Me.TextBox3.Text & ":" & Me.TextBox4.Text & "/default.php")
Request.Method = "POST"
Dim vHeaders As Object
vHeaders = "Content-Type: application/x-www-form-urlencoded" + Chr(10) + Chr(13)
Dim sUserNameParameter As String = "UserName="
Dim sPasswordParameter As String = "Password="
Dim sPostData As String = sUserNameParameter & Me.TextBox1.Text & "&" & sPasswordParameter & Me.TextBox2.Text
Dim oByteString() As Byte
oByteString = ASCIIEncoding.ASCII.GetBytes(sPostData)
Request.ContentType = vHeaders
Request.ContentLength = oByteString.Length
Dim myStream As Stream
myStream = Request.GetRequestStream()
myStream.Write(oByteString, 0, oByteString.Length)
myStream.Close()
Request.Timeout = 10000
Respond = Request.GetResponse()
After that code , I take the response from the asp file and I process the data belonged to the response.
So, How can I post data to php file served by apache server?
Thanks...

Hi People,
After several unsuccessful attempts to use Outlook 2002/ 2003/ Exchange rules, I am unable to autoreply to all mesages received to a particular inbox.
I have set up a new mail enabled user with the sole purpose of autoreplying to messages sent to a distribution list of which this new user is a member.
Are any of you VBS guru'a able to come with something which would do the trick?
Many, many thanks in advance

Hi, i have an item in my tree view as the below structure.
Fruite
A
Apple
B
Banana
C
Sport
F
Football
R
Running
S
Swimming
In this view I assume that Fruite and Sport item is located in the 1st level. For A, B, C, F, R and S is located in the 2nd level and Apple, Banana, Football, Running and Swimming is locate in the 3rd level. My question is, in the run time my user choose Foodball (mean they choose the 3rd level) how could I prompt the user that they choose the 3rd level? Or if they choose S, How could I know that they choose the 2nd level? Can anyone give me a sample code to do that?

How to pack MSDE with the .Net setup and set a sequence that MSDE is installed first and then the application.Although bootstrapper helps in installing MDAC and .Net framework on the target machine if they are not found, how can we set a sequence in bootstrapper to install MSDE.
|
|
|
|
|
Short answer:
1. Install the bootstrapper on your development machine
2. Create a setup project for your app
3. Use the bootstrapper to mask your setup project.
Long(er) answer:
1. you do not have to setup any sequence. The MSDE bootstrapper has the sequence built in already
(Install .Net, Install MSDE, Install your app). You cannot change that sequence. That is all the bootstrapper does.
2.There are some configuration options but they relate to whether you want to use a strong password on the sa account (of MSDE) and/or hard coded paths for the databases. Also some settings for what to dislay in prompts and such...
3. The bootstrapper doc is typical MS (sparse and cryptic) but the bootstraper is so simple that the MS documentation is all you need.

I'm trying to use bootstarpper for deploying msde but to no sucess.tell me in how to use it
|
|
|
|
|
|
i m using the same toolkit sample the problem is at step 3 of MSDE Bootstrapper it says the location does not contain any valid MSDE files which i have populated with sql database file and if u can tell me what to put for four value in the combo box.
|
|

If you are referring to the window that reads
"MSDE 2000 bootstrap loader configurator (Page 3 of 6)", you need to choose a location for EACH of the values in the combo box.
None of those values is the location of YOUR database. Your database should
be packaged with your application's intallation files and the restoring of it
done either manually or programatically by your application. The bootstrapper does NOT do restoring of databases.
The value that should go in the "MSDE Files" option is the location where the MSDE installation files are (the files you'd run if you wanted to install MSDE manually). Nothing to do with your database.
The value should be drive:\whereveryouinstalledthedeploymentkit\template\cd\msde\
As far as your database files are concerned, they should be added to your apps setup package as just another file(s). Then the person who installs the app restores the database manually, OR you write some code in your app that checks for the db and restores it if not there.
Hope this helps.

Using mapi32.dll with vb.net to compose and show a new mail message with attachments works with Outlook Express but not Outlook 2000. I can bring up a message in Outlook 2000 ONLY if it doesn't have attachments. The error returned while trying to attach files is "Unspecified Error"! Anybody knows what's up?
|
|
|
|
|
Cannot access attachments

The files I'm trying to attach are jpg picture files. They are not in the level 1 (unsafe) category. I turned off the security for attachments and it didn't make any difference.

I have a tabcontrol which I have added a MonthCalendar1 to Tabpage1.
Is it possible to display this MonthCalendar1 on another Tabpage?
If so how would I go about doing this? Or would I just add another MonthCalendar to this Tabpage?
Cheers in Advance

Hi There
I'm badly stuck trying to get what seems to be a very simple crystal report to display in the report viewer. I am using the .NET 2003 version of CR (which I have been told that is basically version 9.0) and SQL Server 2000.
I have been through multiple articles/tutorials regarding this issue but all seem to be based on creating design time SqlDataAdapter, SqlDataConnection, DataSet objects. However, I require these objects (or at least the adapter) to be created at runtime as the query that the report can be based on is dynamically built by the user.
So just to get a handle on what is going on I thought I would try a very simple single table query before messing around with the actual multi-table inner-outer join nightmare that I really need. That was three days ago...
I have created a dataset by dragging the single table "tbl_Students" onto the dataset design form. I can't see anything else I have to do here. I also created the crystal report using the report expert and simply added all the fields of the table to this report.
Here is the rest of my code:
Dim adConn As New SqlConnection("Initial Catalog = DBName;Data Source=Server;Integrated Security=SSPI")
Dim adCmd As New SqlCommand("SELECT * FROM tbl_Course", adConn)
Dim adAdapter As New SqlDataAdapter(adCmd)
Dim dSet As New CrsInfo
adAdapter.Fill(dSet)
Dim stuRep As New Students
stuRep.SetDataSource(dSet)
cvwMain.ReportSource = stuRep
I continually get Crystal Report Windows Forms Viewer Error that simply says Query Engine Error with a path to some temp_GUID.rpt file in my user profile. If I do the design time drag and drop with a connection object, adapter object and a dataset object all works well, but this is not what I need. Any help will be much appreciated.
Thanks.

In my cut and paste frenzy, I forgot to change all kinds of things in the code. I'm going to retry and post my results in a minute or two...
|
|
|
|
|
Okay - success!!
Despite my code posting not making any sense let me assure you that that was just a cut and paste error. However the problem really was that when I called the .Fill method of the DataAdapter I didn't specify which table to use for the field mappings. If you don't, the report comes out blank! Hmmmm, what about when I do the real multi-table query? I'm assuming I have to use the field mapping editor with the DataSet - yes?
Thanks everyone for letting me vent and solve my own problem (I hope)...
|
|

Okay, now that I have mastered my single table report, I thought I would plunge into the multi-table report.
But I do have a couple of questions regarding the DataSet design. Do I just drag the tables onto the designer form and that's it? Do I have to worry about the relationships between the tables? Also, I do not require all the fields from all the tables. Can I eliminate some of the fields so the dataset fields more closely match the query? Does it matter one way or the other?
Thus far I just dragged the tables onto the designer and didn't do anything else and surprise surprise my report runs but it is blank. So, besides the above, is there anything else I need to worry about to get this report to run?
Again, any help is much appreciated
Thanks.
