• .NET Development How to remove columns from DataView but not from DataSet table

• SQL Server BCP host-files must contain at least one column

  Hi, I need to export the output of a stored procedure to file. So I am writing a bcp command as 'bcp "exec myproc" queryout "outputfile" -S server -U user -P pwd -n -t, -r "\r\n" '. But I am getting an error 'BCP host-files must contain at least one column'. I am getting this error even if I use a format file. Do u have any idea of what I am missing in it Thanks. Go to Query Analyzer and run this: SET FMTONLY ON exec myproc SET FMTONLY OFF If you get an empty result set with a list of the columns then your stored procedure can actually be used with the BCP utility. Otherwise, a few changes may have to be made to the stored procedure ...Show All

• Visual Basic IDE adds decimals

  Hi! This odd behavior started the other day and I can't seem to find why this is happening. Let's say I have a "dim myVar as single" When I type : myVar = 0.8F The IDE changes it to : myVar = 0.800000012F Any idea why this happens Thx! Ha ! I just went through the Add-In manager and found out that there was an entry for Rational Rose. I unchecked it, restarted the IDE and there you go ! 0.01 stays 0.01 ! Strange stuff !

• Visual Studio Strange about Immediate Window?

  Hi all, The immediate window is great for debugging. But it only allows simple function evalution. However when I tried to execute the following function: mpfr_add_si(u, Ct, k, GMP_RNDN); CXX0026: Error: bad format string It issued the above error message. What's wrong with it Note that "mpfr_add_si(u, Ct, k, GMP_RNDN);" is a correct function call that compiled and executed successfully. But I don't know why it doesn't work in the immediate window. I execute in the immediate window because I want to execute it again after changing some parameter values. ------------------------------- Another question: is there a way to let the immediate window has the prompt sign, such as ">", or ">&g ...Show All

• Visual Studio Express Editions Buttons on Form disabled when using SQL Database

  Ok, I've tried de-bugging this and I can't figure out how to rectify my problem. So far I have a simple application with a simple database. (I'm getting back into programming after 20 years.) I have a list box with names of historical figures. When you click on the name a picturebox on the form changes to that person's picture and there is a 'summary' text box which says a little about them. The list box is bound to the database. It works pretty slick actually. The only problem is that once I click on the list box (and the event ListBox1_SelectedIndexChanged takes place) all of the buttons on the form are unresponsive. Apparently the program goes into a loop where it checks to see if the listbox has changed and continues to do ...Show All

• Windows Forms Textbox scrolling

  When I use textbox.appendtext(buff), buff is successfully appended to the textbox and the textbox automatically scrolls. However, there seems to be a limit... the scrolling stops (as does the data being appended) after a certain amount of data is appended. I have the maxlength set to 0 and have also tried setting it to 1,000,000. I have resorted to: textbox.text+=buff textbox.selectionstart=txtbox..text.length textbox.scrolltocaret() Unfortunately, that scrolls the text all the way to the beginning and then back to the end everytime which causes undesirable flashing. Does anyone know why the appendtext method is limited Hello All. Danny: Hmmm. What version of Visual Studio are you ...Show All

• Visual Basic How should I proceed? Advice, please.

  I'm wanting to use ASP.NET 1.1 and VB.Net to develop a web based control panel for Windows environments. I will be developing on a Windows XP Pro machine but will be debugging on a Windows 2003 machine. My issue though is that I don't know where to begin. My question is where do I begin Some code samples are preferred, if possible, but I'm just looking for a direction to begin. I've done Google searches and MSDN searches for ASP.NET working with IIS but I didn't get much luck in finding anything. Thanks for your help. -Michael I'm not concerned with logins and registrations per se.

• SQL Server Pre-Generating snapshots not working

  Hi I have setup my web synchronisation with very few problems until now. Initially I set the snapshots to generated by the subscriber when they first synchronise, this worked perfectly every time until a bottleneck occured after I reinitialised all the subscribers. When more than one subscriber then initialises the snapshot agent, the snapshot jobs fail because there is already a job running for user distributor_admin. The agent then retries etc, etc.. until all retries have failed. Ultimately only one of the snapshots is successfully created only after all other jobs have failed and run out of retries, it is then left alone to carry out its job. Following this I made the decision to run with pre-generated snapshots instead so that I can s ...Show All

• Visual Studio Help disabling Just-In-Debugging

  I installed .net 2.0 yesterday and now Just-In-Time Debugging has taken over my apps I work on outside of VS.net. I have followed all steps I have found to disable JIT with no results. So then I uninstalled 2.0 and reverted back to 1.1. Still, the JIT dialogue pops up. The pages I am working on are classic asp pages and the last thing I need is these JIT popups. I have been unable to find any information beyond the checkboxes in VS.net. Could anyone shed some light on this If it matters, I am on XP Pro and run VS.Net 2003. Thanks. Hi Habib, Thanks for your response. Actually, all I am trying to do is stop JIT debugger from intercepting the errors and popping up. This never happened with .NET 1.1, ...Show All
