I have a placed a text box control in VB form. When ever user types characters inside the text box, I am populating keywords in a combo box depending on the characters entered. How ever I have a difficulty in follwoing the cursor inside the text box. Let me know how I can get the x and Y co-ordinates of a cursor inside a text box Thanks bala Re: Intellisense Jeremy Falcon11-Jul-02 4:45 Jeremy Falcon 11-Jul-02 4:45  gbala wrote: How ever I have a difficulty in follwoing the cursor inside the text box.

Pradhip10-Jul-02 12:39 Pradhip 10-Jul-02 12:39  Hi Folks.. Im having a web form that has 2 select boxes.Now when one select box has a value chosen it must generate values for other select box.This can be accomplished by querying the dbase.Now to do this querying im using an ASP page. 1). My question is how do i run the ASP Page without it affecting the current window displaying my form?? 2). Now my 2nd select box has to be refreshed for it to be populated with the values that the ASP Page generates.How can i refresh that control alone without touching the other contorls or rather refreshing the entire page.. Can someone give me links to articles regd this sort of stuff.I know im using a round about method..

Ravi_Shankar10-Jul-02 20:59 Ravi_Shankar 10-Jul-02 20:59  Hi You can use HTTPREQUEST Object to call the page which can return the data for the other Select box. Use this data to fill in the same.

The problem is that when I try to use the Package & Deployment Wizard to package it, I get this message: "Below is a list of files for which dependency information could not be found. To proceed without the dependency information for the file(s) listed, click OK. To permanently mark a file as having no dependencies, select its checkbox." 3 Questions: 1) Is it unwise to wrap a DLL around an OCX? 2) How do I create a dependency file for the DLL? 3) If I don't need a dependency file, how can I be sure before actually building the project and installing it on some bare bones PC? Thanks Guys and Gals, Oh, yeah. I also get the dependency information message for: dao360.dll. How can I fix this, too? Re: Dependency Information at P&D Wizard Like2Byte12-Jul-02 3:43 Like2Byte 12-Jul-02 3:43  Here are the answers to the questions I provided (If anyone cares.) Let me just say that everyone has a purpose in life and sometimes that purpose is to set an example. This is a case of an example of something to NOT do. <<1) Is it unwise to wrap a DLL around an OCX?>> This could be argued for or against, i guess; but, be forwarned - It's a bitch to get the thing working in a distributable package. That being said, I killed the dll project. So, for a newbie VB Programmer, Yes. Without a doubt - don't try it. I'm sure someone knows how to do this, though it ain't me. <<2) How do I create a dependency file for the DLL?>> The package and deployment wizard has a dependency file wizard that works pretty well. It detected all the dependency information for another dll we wrote. However, the one I was working needed much more information than it could generate automatically. Since sometimes "less is more,' I'm going to end with that. <<3) If I don't need a dependency file, how can I be sure before actually building the project and installing it on some bare bones PC? >> Now that I know a little bit more about dependency files, I'm no expert therefore I shall not even try to submit information to someone else on this as I may 'bum-dope' someone. I have my theories; but, they are largely untested. In closing, it was a foolish idea to wrap an ocx in a dll and think that the interface I was writing would be 'easier.' But, hey, I learned something for it which is better than nothing. Later. Re: Dependency Information at P&D Wizard Like2Byte22-Jul-02 10:37 Like2Byte 22-Jul-02 10:37  OK. Well, it was bugging me. I fixed my problem. Hmm, acutally, I worked around it. I wrote a script to copy the associated DLLs, TLBs and OCXs to the future installation directory then registered each and every one using regsvr32. Then I ran the setup.exe. It worked great on systems that didn't contain any of the DLLs, TLBs or OCXs. So, there! Database Problem BHBAD10-Jul-02 4:26 BHBAD 10-Jul-02 4:26  Hello all, I am having a bit of a problem with databases. Right now I have an application that stores data into an access database. But when the database goes over 2 gigs the application crashes out and it starts over writting the header file. Please give me some suggestions with using other database collectors, that would be a great help.

If so, try something like this - Dim myDir as new System.IO.directoryInfo("\\ServerName\directory1") myDir.CreateSubdirectory("New Directory") Or are you doing this with remoting? In that case you'd create a public procedure in the shared server object that would look something like the above code. Then just access it from the client. I hope this makes sense. If not or if you have further questions, just reply -Steve Re: How can i create Folder on server from client Pradhip12-Jul-02 5:03 Pradhip 12-Jul-02 5:03  TRY THE OBJECT CALLED ASP UPLOAD 2.0 BY DUNDEE SOFTWARE.its good and easy to use and pretty decent documentation is avbl..i use it for my asp page..

Validate Property Pages Ravi_Shankar7-Jul-02 21:23 Ravi_Shankar 7-Jul-02 21:23  Hi, I want to know how to validate a property sheet and if validation is success, pass the control to the property page two and if not, pass the control back to page one. Suppose I have 2 propoerty sheets in a page. I do some validation in page one and if the validation is a success, pass the control to page two, else have the control in page one itself.

As for not advanceing if the validation fails return -1 and you will stay on the same page.

MStanbrook7-Jul-02 12:43 MStanbrook 7-Jul-02 12:43  Back in the 'ol days of VB6, debuging a DLL was as easy as instanciating an object (set x = new ABC) in the Immediate window and stepping through the code. IS there ANY sort of parallel in the .NET world? I've only been able to debug VB.NET dll's via a reference in a windows form project. TIA.

At least that's what I had to do under ATL. I don't see that anywhere in your code. I think I use AtlAdvise and AtlUnadvise? Todd Smith
